Review of the Kawasaki Ninja 600 (ZX 6R) sports motorcycle

The Japanese motorcycle “Kawasaki Ninja 600” was produced at the Kawasaki Motorcycles factories from 1985 to 1995 and was intended for road racing. The car has distinct features of a racing car, and the powerful engine, which allows it to reach speeds of up to 280 kilometers per hour, leaves no doubt about the outstanding technical characteristics of the fast bike.

Model overview

The engineers have worked hard to put together a motorcycle that combines power and agility perfectly.
Thanks to the 600cc engine, this bike reaches a maximum speed of 280 km/h, but its low weight makes it agile on the most difficult turns.

Now a few laps on this bike have become an exciting ride at incredible speed.

In addition to ideal weight and excellent speed, the Kawasaki Ninja 600 received its main parameters from the Ninja ZX-6RR, which had previously been released in limited quantities.

So, let's get started with a detailed review of this racing car.

1. Frame. Most likely, even on the drawings, the engineers had an idea to create a frame with maximum harmony between a rigid landing and flexible control.

   Thanks to this design, at the beginning of a turn, synchronization with the steering wheel is absolutely maximum.

   To create such a balance, it was necessary to calculate the location of the pendulum and the position of the motor.

   The Kawasaki Ninja 600 ZX 6R has a frame made of a single unit, thanks to which the motor moves simultaneously with the frame. This design allows you to move all the weight evenly, gaining greater speed.

2. Engine. The main aspect of the engine is the slipper clutch. When making a sharp jerk on a turn, the pilot will not need to fear falling.
3. Suspension. In a motorcycle, the suspension can be adjusted depending on the type of road on which the bike will be ridden.
4. The brakes are powerful.
5. The landing is sporty.

A trainer for beginners?

According to a survey of Kawasaki owners, the Ninja 250 is popular among beginners, and 33% of sales are to women. It's no surprise that one of buyers' top considerations is price. It is only $3,499. Before the design change, the motorcycle with a rather weak engine with a displacement of 250 cm3 was intended especially for beginners. But everything changed after 2008, when the engine was updated by 70%, and the style of the motorcycle was borrowed from the sports models Ninja ZX-10R and ZX-6R.

Owners' opinions

We all know that no matter how beautiful the device looks, before purchasing it, you need to read the reviews of motorcyclists who managed to purchase the model they liked. Owners characterize Ninja bikes as a very fast option, capable of accelerating up to 180 km/h, so they recommend spending money on buying a helmet

Some car enthusiasts note the rather expensive spare parts for Kawasaki and focus on safety, because driving over 150 km/h can only be accomplished by experienced bikers. Others do not notice the shortcomings at all, praising the motorcycle’s fast acceleration and low fuel consumption

When purchasing one of the Kawasaki bikes, you must remember that you are getting a high-quality motorcycle from a reliable Japanese manufacturer that will be able to meet all your expectations, delivering only positive emotions from owning the machine.

Riding experience

According to owners, the motorcycle's two-cylinder engine chugs a little and its squat stance is a bit lazy if the rider is used to an aggressive riding style. However, it allows you to easily adjust the acceleration and speed. If you pull the clutch and engage the gear, you will notice that the lever has a long stroke. The engine revs gradually and becomes noisy around halfway to its maximum 13,000 rpm. Acceleration can be brisk enough to keep up with traffic or merge onto the highway, but you should keep the engine at maximum power level. If you change gear too early, you may miss the optimal rpm to achieve good acceleration.

The low weight of the motorcycle makes it easy to maneuver, and changing direction is done with minimal effort. If you keep the revs high, the Ninja 250 will be a pleasant ride on winding roads. The transmission behaves well and shifts with positive feedback most of the time, although at times it falls into false neutral between the two. The green neutral indicator sometimes does not light up. The brakes are much better and get pretty good reviews. Thanks to its light weight and maneuverability, riding the Kawasaki 250 Ninja sportbike is a fun and rewarding experience that will allow beginners to easily master riding techniques and more experienced riders to hone their basic skills.

What do the owners say?

Judging by the reviews from the owners of such bikes, there is little difference between a new version and a used one in good condition. However, even used owners still advise buying a new car if possible.

It is not always possible to fully understand how the previous owner used the motorcycle. And this affects its future condition, maintenance and safety of the rider.

It was noticed that the bike picks up speed well and passes through oncoming air flows, but its handling is not the best in its class. However, this is sufficient to enjoy a more or less comfortable and safe ride at not the highest speeds.

Owners also note that this bike has a convenient instrument panel, which is clearly visible in the dark and fog. No need to bend over to see the indicators

And this is critically important at high speeds, as is clear from any first-person video on a sportbike

In conclusion, it is worth noting that the Kawasaki ZX-6R (636) is suitable for sports class connoisseurs. Especially if you like modern bikes and not the sports classics of the eighties. The car is responsive and expressive. But you can only do this after a weaker sportbike, so as not to get into a dangerous situation.

Ergonomics and design

Users recommend an upright riding position, which, unlike an inclined one, is more gentle on the lower back and does not put additional pressure on the wrists. Restyling has introduced comfortable ergonomics, thanks to which the driver's position has become much more natural.

Weighing only 152 kg, the Kawasaki Ninja 250 motorcycle is very light and can be easily removed from the stand, which is a definite plus for beginners. The stepped seat, composed of two parts with a forward slope, helps the driver maintain the correct position. Its passenger side is slightly higher than the front. The seat height is only 77.5 cm - this is the minimum for a sportbike. The rear seat can be hidden under a striking cover in the color of the motorcycle body. A short driver (1 m 67 cm) wearing low-heeled boots can stand firmly on the ground while stopping. The seat is narrow enough not to restrict those wearing short-legged trousers.

Exterior design of the sportbike

The Kawasaki Ninja 600 has an impressive appearance with a sporty style.

The first thing that catches your eye in the foreground are the high-brightness dual headlights.

The style is also complemented by the Ram Air air intake system, which is placed in the center of the bike.

Turn signals are built into the front fairing.

The wing at the front has acquired an aerodynamic shape.

At the rear, the turn signals are quite small and cone-shaped. The rear light is equipped with bright LEDs.

It precisely projects the shape of the rear fairing and is located high above the road level, which ensures maximum visibility of the motorbike on the road.

The instrument panel is made in a racing style and consists of:

• Gear adjustment indicator.
• Digital speedometer.
• Diagram tachometer.
• Digital thermometer.
• Stopwatch.
• Watch.
• Indicator lamps.
• Odometer.

In addition, it can be noted that the exhaust system is made of stainless steel. The sporty style is reflected in the passenger footrests.

The mounting panel was made in the form of a triangle with special cutouts. The bike frame has a black finish.

Ninja 250 wins the hearts of racers

This model from the famous Japanese manufacturer was destined to become both a sports and a traditional motorcycle for drivers of various skill levels.
Featuring a 249cc twin-cylinder engine producing 27.6 hp, the sportbike is capable of delivering 1.4 miles in 14.6 seconds. In addition, it is difficult not to note the significant advantages of the motorcycle, such as ease of control and low seat position. Comfortable movement on city streets on one of the most stable motorcycles is also ensured by the classic landing and a two-piston disc brake, which is characterized by high sensitivity to touching the brake lever. One look at this car, thought out to the smallest detail, is enough to realize that this is the most stylish and ergonomic motorcycle in its class.

In 2008, fans of the 250 model could notice significant changes in it, which affected both the technical characteristics and design of the motorcycle, and also influenced the increase in its cost. The developers decided to attract professional racers to their motorcycle by increasing the wheel size and front suspension. Innovations also affected the appearance of the motorcycle, which began to look more modern.

Short flight

The lower rake angle of 26°C makes steering and cornering easier. The shorter the reach, the easier it is to make tight turns. According to reviews from drivers who drove on narrow roads, it was easy to turn around on them if you looked in the direction of the intended movement and did not put your feet down. The motorcycle also received new 6-spoke 17-inch wheels (instead of 16”) with low-profile tires, providing greater stability. In addition, this size is more common and allows you to find tires to suit your taste.

Notable Features

Among its competitors, the Kawasaki Ninja stood out with its strong chassis, excellent handling and amazing speed, thanks to which it practically destroyed its rivals.

In the eighties, 243 km/h was an absolute record for the class of road bikes.

In addition to its extreme power, the model was also distinguished by the phenomenal reliability of the DOHC power plant, which had four cylinders, sixteen valves and liquid cooling, as well as four carburetors, known as Keihin CVK4.

With an engine capacity of 908 cc, it produced 115 hp. s., and in the modification for European countries - 100 l. With.

• ZX-6R 2019+. It is a restyling of the 2013 model, differing mainly in appearance. Still in production today.

conclusions

So what do all these improvements mean for those interested in this bike? The result is a more comfortable ride and improved ergonomics. Increased throttle sensitivity is very important, especially for beginners who are just getting used to handling the throttle. Increased torque at low and mid-range speeds allows you to feel the power of a quick start. An improved braking system and smoother gear shifting are always a good thing. In addition, cornering was simplified, the instrument panel was updated with the addition of a fuel level sensor, and the body was completely replaced, which provided the motorcycle with a modern and stylish look.

But the most important thing is that despite all these significant improvements, the price has increased by only $500.

Specifications

The Kawasaki Ninja motorcycle has the following dimensions:

• Length - 222 cm;
• Width - 74 cm;
• Height (in the village) - 122 (79) cm;
• Wheelbase - 150 cm.

Its curb weight is 234 kilograms, and the gas tank capacity is 22 liters.

The frame of the GPZ 900 R is made of steel tubes and has a central spine. The chassis is made with a large margin of safety.

The UNI-TRAK suspension is equipped with a monoshock absorber. The gearbox is six-speed.

More power

Early versions of the 250R required higher rpm (i.e. more fuel) to simply shift out of first gear. This was difficult for new riders who are just learning to identify where the friction zone is. The new Kawasaki Ninja 250 has plenty of low- and mid-range torque for quick acceleration and smoother launches without requiring the driver to open the throttle as much. The technical specifications of the motorcycle indicate that its maximum torque is 18.4 Nm at 9,750 rpm. You can even mistakenly start in second gear instead of first. Most bikes allow this without any consequences. You can crank the throttle to quickly increase the revs to second gear without interrupting the engine. However, the 250R was not very forgiving to such a start.

Brake system

The brake discs are large here. Their width is 6 mm and diameter is 300 mm. They are made of stainless steel.

Thus, the brake force will be very strong each time you apply them.

It often happens that even experienced riders find it difficult to discern which gear is currently in use while riding.

To prevent such situations, the digital display is installed in a large size.

It is able to instantly display all the most important information for the rider - speed and gear number.

The ZX-6R model has cylindrical airbox guides. They help ensure accurate spraying from the fuel injectors.

As a result, better fuel atomization improves combustion efficiency. Accordingly, the engine output will be greater.

Technical characteristics of Kawasaki Ninja 600

In 1995, the Kawasaki ZX-6R 600 cm3 sports bike was released, which ideally replaced the ZZ-R600 model.

The ZX-6R motorcycle was equipped with a powerful engine, high-quality handling and excellent practicality.

The ZX-6R didn't have much technical innovation other than the cross-ply aluminum frame that was new to the 600cc sports bike in 1995.

It is also worth noting that the liquid-cooled engine with a four-cylinder in-line 16-valve system has become one of the most powerful bikes in its range.

In 2001, the ZX-6R was modernized. Significant modifications were made to the “stuffing” of the motorcycle, thanks to which the motorbike became more advanced in handling. The carburetor engine, in addition to unsurpassed power, has impeccable traction for medium and low crankshaft speeds.

In the same 2001, Australian Andrew Pitt won the world champion title on a Kawasaki ZX-6R sports bike in the Supersport competition class, which confirmed the maximum potential of this motorcycle.

Transmission

The clutch is a little stiffer than you'd expect from an entry-level bike, but that's certainly not a deal-breaker. Once you get going, the updated 6-speed transmission shifts smoothly and there's never any trouble finding neutral. All Kawasaki motorcycles are equipped with the manufacturer’s proprietary technology, which allows you to do this without difficulty. A green light on the instrument panel confirms when the transmission is in neutral.

Having achieved perfection

The classic lime green Ninja 6R was designed to be the best sports bike in its class, and numerous race victories testify to the designers' success in achieving their goal. In an effort to proportionally distribute the weight of the motorcycle and minimize air resistance, Kawasaki managed to create not only an impressive model with its technical characteristics, but also decorate it with a sophisticated Supersport-style design.

The stunning 600cc engine impresses with its power and top-end speed, and is perfectly matched by light handling and improved suspension. Excellent cornering characteristics along with precise throttle control guarantee lightning-fast response to driver inputs, and the cassette gearbox increases engine efficiency. The lightweight aluminum body and perfectly adjustable front and rear suspensions provide the most comfortable and smooth ride.

The updated Performance Edition, released in 2012, features an upgraded muffler and a scratch-resistant windshield designed to improve aerodynamics. The 2013 sportbike will surprise fans not only with an even more stylish design and enhanced safety system, but also with the ability to select engine modes thanks to the latest advances in programming.

How this is achieved

Excellent cornering performance

One of the biggest truths Kawasaki has learned over the years is that maximum power is important on the race track. But it doesn't solve everything. To go fast on the highway, the driver needs to take corners smoothly. Even under heavy braking, he must be able to hold and even correct the car's line mid-corner, then release the throttle early for a powerful exit. It is the exit speed of the turn that ultimately decides how quickly he can overcome the straight section. To achieve this goal, Kawasaki engineers and testers applied the knowledge gained from many years of racing and sports car construction to the 10R chassis and carefully studied the static and dynamic centers of gravity. The 10R's power curve has been re-calculated to lift it in the mid-range and improve power delivery linearity across the rev scale. All this ensures that the new 10R will be the best big-cylinder track machine of 2006.

Race track chassis

• The designers moved the engine to place the crankshaft higher. Thanks to this technique, as well as changes to the frame design, it was possible to further raise the center of gravity and increase the concentration of the machine’s mass. A higher center of gravity improves the bike's responsiveness during roll changes. This is especially noticeable when the rider throws the bike from side to side through a series of high-speed corners, or returns the car to an upright position on the exit of a corner.
• The decision to raise the center of gravity entailed comprehensive changes to the engine design. With the new engine design, the designers increased the cylinder angle from 20° to 23° (with the final center of gravity moving out from behind the cylinders towards the end of the crankshaft). The starter clutch was moved from the left side of the cover to the right, placing the starter itself behind the cylinders. This move does not increase the width of the engine, which helps the car maintain an excellent bank angle of 52°. (Photo)

• Although the steering head has moved forward and the chassis geometry has changed, the wheelbase itself has not undergone any changes.
• The new frame uses castings for the steering head assembly, as well as rigid engine mounts, both of which change the balance of frame rigidity.
• New is the use of cast parts in the heel area of ​​the foot shifter, as well as stamped parts for the beams and stabilizer. (Photo)

• The heel position of the foot shifter has also been raised. Together with larger rear tires (190/50ZR17 -> 190/55ZR17), this provided excellent rear wheel traction when cornering. The raised position of the heel of the foot switch allows you to expand the range of its settings. (Photo)
• For racing purposes, the car is equipped with a racing-type steering damper, which, however, can be removed for street driving.
• Comprehensive chassis upgrades make the 10R a trail machine with great potential. At the same time, the motorcycle has excellent handling, which is necessary for super-sport enthusiasts for racing and city riding.

Uniform power take-off

Since the 10R produces the same torque as a conventional motorcycle in 1st, 2nd and 3rd gear (and therefore the same reverse torque), controlled power take-off becomes increasingly important. To give the car greater stability when entering a turn, the designers increased the mass of the crankshaft flywheel. The increased mass prevents the rear wheel from jamming when releasing the gas, and helps the sliding clutch overcome wheel surges more effectively. Thanks to the increased resistance to wheel spin in 1st, 2nd and 3rd gears, acceleration after a turn has also improved. The throttle control works excellent.

The new engine's more linear performance indirectly improves the car's corner-exit performance, giving it more power in the mid-range, both of which significantly improve acceleration out of the corner.

A new throttle pulley reduced the load on the throttle, and engine diagnostics showed flatter intermediate power characteristics when the throttle was applied again at the exit of a turn. It also provided smoother throttle response when applying and releasing throttle on city streets or winding roads.

Other advantages

• The front brake's powerful effect is further enhanced by a new hydraulic radial-actuated master cylinder that gives the driver excellent feel at the lever. (Photo)

• The foot shift lever and its redesigned linkage make shifting easier. (Photo)

High effective power

One of the key reasons for the new 10R's increased racing capabilities is its incredibly high power output. The engine's huge power output, enhanced mid-range power and improved aerodynamics allow for quick acceleration out of corners and straightaways. Despite its impressive power, the 10R is an environmentally friendly machine that meets Euro III gas emissions standards.

Increased power while decreasing weight

The 16-valve engine, with a displacement of 998 cm3, a liquid cooling system and two overhead camshafts, benefited from a set of major changes aimed at reducing friction losses, which resulted in an increase in power throughout the entire rev range. (Photo)

New, micro-spray injectors deliver fuel to 43mm-long throttle bodies equipped with dual throttle valves. Improved atomization of the mixture, with droplet sizes of the order of 50 microns, increases the thermal efficiency of the cylinder, contributing to increased power output, greater linearity of power take-off and a smooth, non-sharp torque curve. (Photo)

The higher engine position allows the resulting center of gravity to be positioned behind the cylinders closer to the end of the crankshaft without compromising the bike's extreme roll. As a result, power is increased and at the same time the weight of the engine is reduced.

For better cooling, the new lightweight Denso radiator is equipped with a dense internal baffle system. (Photo)

The weight of the machine is also reduced by a new one-piece saddle guard.

Compliance with Euro III standard

• The dual exhaust system, which has a racing profile and is routed under the seat, features a 4-2-1-2 layout, with oxygen sensors mounted above the 2 catalytic filters (one each in the manifold). The signal from these sensors is used to control the exhaust temperature, ensuring low gas emissions in accordance with Euro-III standards. (Photo)

• The 10R's reduced gas emissions (and increased power) are also aided by new micro-spray injectors positioned at a new angle and closer to the intake valves. These injectors significantly improve the atomization of the air/fuel mixture, providing greater power output and cleaner exhaust.
• The all-titanium exhaust system uses a distributor throttle that controls the pressure pulses inside the exhaust pipes, which ensures uniform power delivery throughout the engine speed range.

Engine characteristics of the 2006 ZX-10R “Ninja”

Optimal dimensions of the intake and exhaust ports, calculated by flow analysis, ensure efficient filling of the cylinders and high power production. Exhaust valves made of titanium reduce the weight of the piston group and provide excellent performance at high speeds.

Iridium plugs provide a hot spark and high voltage coils provide high thermal efficiency.

The surfaces of the cams and camshaft plates have undergone a soft nitride treatment, providing parts with durability and reliability at high speeds.

Valve spring retaining rings are made of sintered aluminum, reducing the weight of the piston group, providing reliable valve control at high speeds.

Forged pistons are lightweight and highly durable, providing low piston weight and high heat resistance. Their flat top allowed the creation of a compact internal combustion chamber with improved performance characteristics.

Anodized cylinders are highly wear-resistant and provide excellent heat dissipation. Grooves in the cylinders ensure efficient crankcase ventilation and reduce pumping losses.

Intake air is directed through the central ram-air duct and through the frame pipes into the air filter housing. The channel between the frame and the air cleaner blocks the access of moisture.

A small air filter fits between the frame crossbars, allowing for a seamless, high-capacity, flat-bottomed fuel tank. In-line analysis method was also used to ensure efficient air flow inside the air filter.

The one-piece cylinder/crankcase design, compact cylinder head, and 3-shaft crankcase gearbox resulted in a surprisingly compact and lightweight engine. The latter was so short that it fit between the double frame rails, giving the 10R the narrow, compact profile of a 600cc class machine.

Single-valve spring shock absorbers are made of oval-section wire, which made it possible to implement a design of short springs and a compact cylindrical head.

The camshafts are machined from forged blanks (SCM420K steel), which provides the product with low weight and high strength.

Lightweight engine covers are made from magnesium alloy, keeping the engine lightweight.

The water-cooled oil cooler with internal aluminum fins is lightweight and helps control oil temperature.

Improved aerodynamics

One way to increase the speed of a motorcycle is to increase the engine power; the other is to reduce air resistance. Since the motorcycle already has plenty of power, when creating the new 10R, the designers decided to take aerodynamics seriously. At first glance, it is clear that this machine turned out to be purely functional. A new hood, seat fairing and dual under-seat exhaust system have significantly improved the car's aerodynamics, especially in the upper speed range. At a speed of 280 km/h, the smooth, aerodynamic shapes are equivalent to 7.5 kW of power.

Exterior of a racing car

The aerodynamic shape of the newly designed front fairing is very effective at higher speeds. In race conditions, this reduction in drag can have a significant impact on lap times. (Photo)

The design uses new, ultra-light and very compact projector-type headlights. This gave designers more freedom, allowing them to create an improved aerodynamic fairing and an even more efficient ram air intake. (Photo)

The reshaped rear seat fairing improves air flow around the rear of the vehicle, reducing negative, braking turbulence. This also gives the car a stylish look.

New twin and under-seat exhaust pipes also reduce the vehicle's drag, since the mufflers do not create turbulence or air resistance. (Photo)

Front and rear turn signals built into the fairing reduce wind resistance and look very impressive (Photo).

Racing arsenal

The new 10R is designed to be ready for lap racing right out of the box. The developers made sure that the driver had everything he needed to go straight from the garage to the track and practice timed laps.

Complete kit for winning the race

The machine's standard equipment includes an Öhlins adjustable steering damper, featuring a twin-pipe design and a safety valve. The second tube, which acts as a free reservoir, and the damper device guarantee stable vibration damping even under racing conditions (no foaming occurs even when the damper fluid inside the cylinder is heated). This racing device was developed specifically for the ZX-10R "Ninja in conjunction with". The damper is equipped with a structural clamp, so that nothing interferes with the movement of the piston. (Photo)

The all-new hybrid instrument panel provides information about all the 10R's operating parameters at a glance - a vital feature when you can't take your eyes off the track for more than a split second. The new technology creates the illusion of some distance from the display to make it easier for the driver to change the focus of vision. The new instrument layout features an analog tachometer and an easy-to-read digital speedometer, both with LED backlighting. It is adjustable and has 4 brightness levels. The designers also left the usual instrument “stuffing” in the form of a lap and clock stopwatch. (Photo)

The standard rear tire size (190/55ZR17) is consistent with racing-style tires for increased traction.

Racing driving position

All the ergonomics of the new 10R are designed with racing conditions in mind, from the concave top of the fuel tank that allows you to hide behind a low windshield, to the narrow, “fitted” shape of the tank that allows you to support your knees without creating excessive drag. In addition to the above, the perfect relationship between handlebar, saddle and footpegs makes the machine surprisingly comfortable for street riding too.

Ergonomics of speed

To make the 10R as comfortable to use as possible, the driver's seating position was carefully designed.

The narrow frame and engine create an overall narrow package, allowing the rider to keep his knees as close together as possible. (Photo)

The shape of the fuel tank, narrow at the rear, conforms to the driver's legs, allowing the driver to hug it with his knees and shelter himself from the air flow. (Photo)

Thin overlays on the upper frame braces give its surfaces additional roughness.

Pleasant trifles

There are a lot of nice things about this car. Even when stationary, the Ninja looks like it's racing at 200 km/h. It's the attention to detail that makes Kawasaki sports cars stand out from the rest.

Frame

• A redesigned front fairing, including a Kawasaki-badged air intake and new compact projector headlights, give the 10R a dynamic feel (Photo).
• The front and rear turn signals built into the housing are equipped with clear lenses and orange light lamps, which highlight the high-quality performance of the machine (Photo).
• Details like the aluminite finish on the triple upper fork mount, the molded shape of the passenger footpeg brackets and the flush-mounted fuel filler cap give the 10R the structural charm of a super-sport machine (Photo).

• Aerodynamically shaped mirrors look great and provide good visibility.
• A seamless fuel tank design with a new cap enhances the quality look and feel of the 10R. (Photo)
• The 3-section front wing of the car has a perfect, aerodynamic shape, imparting lightness to the front of the car. The miniature inner wing is lined and helps create laminar airflow around the rear wheel.
• The LED taillight is flush with the body and curves slightly at the top through the seat fairing, making the 10R highly visible to drivers of tall vehicles (Photo)

• The frame is finished in matte black, enhancing its dynamic, racing look.
• High quality workmanship and excellent finishing are ensured by machine welding.
• The double saddle can be replaced, as an optional option, with a single one with a cover, which will give the car even greater dynamism. (Photo)

Frame

Like the ZX-RR, the 10R's chassis design minimizes the distance between the steering bar and the tail, creating a compact, handling package.

The massive, reinforced foot shift lever is a completely new design and provides the rigidity required by a powerful ZX-10R class machine. The long derailleur design reduces engine pressure on the rear suspension, providing excellent suspension performance and excellent road holding. The frame configuration is specially selected to provide it with good axial rigidity and increased elasticity in the longitudinal direction. This "balanced elastic element" contributes greatly to the 10R's brilliant handling. Amazingly light, the frame weighs the same as a similar part on the ZX-6R.

Suspension

• The very stiff ∅ 43mm reverse fork is fully adjustable and features a tuning more suited to the trail. (Photo)
• An ultra-hard, diamond-like graphite coating on the outer surfaces of the fork's internal telescopic tubes reduces sliding friction (static friction) and improves suspension performance, especially in situations where the suspension is subject to heavy loads, such as when braking or changing the motorcycle's roll. Although this surface's excellent performance is best experienced on the track, it also makes the street ride noticeably smoother. The enhanced hardness of the coating helps prevent scratches and damage to pipes.
• For stability, the front and rear suspensions are equipped with additional peak springs. Because these springs adjust suspension extension, the driver will experience less forward thrust under heavy braking following hard acceleration and will gain more stability when reapplying the throttle after hard braking.
• The rear gas shock absorber with reserve capacity and linkage is fully adjustable (Photo).
• A lightweight aluminum suspension link reduces chassis weight and contributes to rear suspension responsiveness.
• The lifting height of the rear wheel is adjusted using chocks.

Brakes/Wheels/Tires

• The ZX-10R “Ninja” was the first production “super-sports” motorcycle to be equipped with petal-type brake discs. This unique disc shape improves cooling and helps prevent warping. These discs are also lighter than conventional ones (Photo).

• The new front brake master cylinder is hydraulically actuated and operates the twin 300mm front discs. Radial 4-wedge opposed calipers with 4 independent pads provide effective machine stopping and excellent control feel (Photo).

• A lightweight 220mm petal disc at the rear wheel is controlled by a lightweight, single-piston caliper.

Engine

• The idle speed system makes the engine easy to start.
• Internal oil supply occurs through grooves machined into the mating surfaces of the crank boat. This eliminates oil lines and simplifies the conventional oil supply system.

Chassis

• The control immobilization function built into the ignition switch system on most European models helps prevent theft of the motorcycle.
• The narrowness of the end of the fuel tank and the front of the saddle allows the rider to easily reach the ground with both feet when braking at traffic lights when driving on the streets.
• The compartment under the saddle has reserve space for a watchdog unit (Photo).

Productive and fast

The Kawasaki GPZ 900 R appeared on the market at the end of 1983, however, its history dates back 6 years before that moment.

In the late seventies, Kawasaki created the Z 1000 sports motorcycle, intended to participate in the AMA Superbike series in the USA and, subsequently, winning many victories on this track.

The next stage in the evolution of the bike was the road modification GPZ 1100 F1, which received a very hot temperament and accelerates to 240 km/h.

The immediate predecessor of the GPZ 900 R is the next creation of the Japanese concern Kawasaki, the GPZ 750 R sportbike, which differed very favorably from its competitors, both in its excellent speed and ride comfort.

Maintaining their leadership and strengthening their position, the engineers increased the engine capacity of their flagship.

In this form, with a 900 cc engine, a rear suspension equipped with a monoshock absorber, and a plastic fairing in the stand, the GPZ 900 “Ninja” motorcycle appeared before the world community.

The model instantly gained the status of a global bestseller, although it was sold in Europe, where the power of heavy motorcycles is regulated by law, in a “cut down” version to 100 “horses”.

Among connoisseurs, the 86-94 models are considered cult, and the “nine hundred” were sold more than 70 thousand copies.

Control and maneuverability

The Kawasaki Ninja ZX-6R motorcycle has a bold and aggressive appearance.

Its weight is reduced, the exhaust pipe is short, and the chassis design has undergone major changes.

As for the power unit, it has also undergone significant modernization.

Its maximum balance allows for much better power transmission at different operating speed ranges.

Therefore, we can say that the Ninja 600 was created specifically for track competitions. The latest equipment has been installed here.

The engine contains magnesium parts, and this has a positive effect on the weight of the two-wheeled unit.

The unique design, which was worked on by the best engineers in the world, allows the biker to easily negotiate turns while moving at high speed.

The rider's reaction is quickly taken into account by the motorcycle. This is facilitated by the ideal balance of the suspension and frame rigidity.

It uses the latest fork with tuning elements, as well as a proprietary steering damper.

But that is not all. Strong radial brake calipers and a sliding clutch design make handling even easier.

Stability and reliability

How does a 250cc engine perform at high speeds? The motorcycle is stable and reliable, moving at a speed of 110-120 km/h. After shifting into sixth gear, the speedometer showed a relaxed 120 km/h at about 8000 rpm. According to user reviews, the new windshield provides a decent level of wind protection without allowing too much wind to blow on the driver. When driving on bumpy roads in the city, the improved suspension of the motorcycle is immediately noticeable. If earlier, when entering such a section, one could expect a noticeable blow, now the small Kawasaki 250 Ninja turned out to be at its best. The new front fork is slightly thicker than the previous one and provides better stability and greater stability. The rear shock absorbers have 5-position preload adjustment. This means you can loosen or tighten the factory shock absorber settings to prepare for carrying a passenger or luggage.

Dimensions and weight

The wheelbase of the motorcycle is 1410 millimeters, which is quite enough for a classic mid-ranger. The length of the bike is small - only 2055 millimeters. The width matches the length and is 740 millimeters. The saddle height is average, reaching 790 millimeters. The height of the motorcycle itself is 1135 millimeters.

With such average dimensions, the motorcycle also has a quite suitable average weight - 193 kilograms. From all of the above it follows that the bike is well suited for people of average height and physical strength. If a person who is too tall chooses such a motorcycle, the handlebars will simply rest on his knees. At the same time, a rider who is too short will experience other difficulties with landing and control.

Inconvenience in the driver's seat of a vehicle is a very unpleasant and dangerous factor that should not be allowed.
