The Stealth Tactic 50 scooter did not shine with impressive technical characteristics, catchy design or other advantages even at the moment when it first went on sale. Why did he become so popular? It's simple - dealers offered it at very low price, and this has attracted a large number of thrifty buyers for whom the cost of purchase and maintenance is of paramount importance. Over the past years, tens of thousands of copies of this model have been sold, and many of them are still in use, because there are no problems with spare parts, and budget motorcycles are always relevant.
Specifications
To keep the cost of the model at an affordable level, the Stealth Skif moped was designed using the most budget-friendly technologies. Therefore, its technical characteristics fully correspond to the price, and they are separated from modern motorcycles by the same gulf as the one that separates steam engines and space rockets.
Engine
Constructed using the best half-century-old technologies, the 2-stroke Stels Skif 50 engine develops 4.9 hp, which is noticeably more than that of 4-stroke “fifty kopecks”. But these are just dry numbers - the acceleration dynamics are very sluggish, and the maximum speed of 60 km/h is reached in about 15 seconds in the absence of a headwind. The engine is quite voracious, and besides, it consumes not only gasoline, but also oil, which is poured into a separate oil tank.
Transmission
Stealth Skif 50 is equipped with a continuously variable transmission. It works properly, and in the reviews of owners there is no information about breakdowns of this unit, but the archaic design is reflected - the variator is very noisy, and when accelerating it desperately howls, as if the scooter is trying to accelerate to the speed of a racing car, while in fact it barely goes 50 km/h.
Chassis and brakes
There's nothing easier than a budget 50cc scooter! A steel frame, weak brakes, which, however, are quite sufficient for such a light vehicle, basic suspension - that’s all. The Stels Skif 50 has stiff suspensions and no adjustment, so you have to get used to the fact that every pebble on the road transmits a full range of sensations exactly to the owner’s bottom. It’s also better to throw out the standard tires that are installed in the cabin right away, replacing them with something better. You shouldn’t rely on the rear drum brake - it’s frankly weak, but a simple 1-piston caliper coupled with a brake disc on the front wheel does the job normally, providing predictable braking.
Electronics
This model has nothing more complicated than a battery, generator and lighting equipment. Since we are talking about a budget scooter, you shouldn’t be surprised that the cheapest components were used, but all electrical problems arise due to assembly flaws. If, after purchasing a scooter, you independently check the insulation of the contacts and carefully lay out the untidy hanging wires, everything will be fine - the electrical circuit is so simple that there is practically nothing to break in it.
Weight and dimensions
The dry weight of the scooter is only 82 kg, and its dimensions are similar to hundreds of other scooter models. It’s easy to handle, and if you happen to drop the moped, picking it up won’t be difficult. There is a downside to this compactness - tall drivers will feel cramped on the Stels Skif. And if there is a passenger, it will be cramped for both, and always - the seat is intended for two only conditionally.
Controllability
Thanks to its modest weight and compact size, the Stealth Skif easily darts between cars, crawling into any hole in which a larger bike might get stuck. The situation is overshadowed only by frankly oak suspensions, not adapted to sudden maneuvers. But taking into account the fact that the scooter is not capable of developing high speeds, it would be unfair to reproach it for this fact.
Fuel consumption
Claimed fuel consumption is 2.5 liters per 100 km. But, according to reviews from owners, the real numbers are noticeably higher, up to 3.5 liters! The volume of the Stels Skif gas tank is 5.2 liters, so you can calculate the power reserve yourself, but it consumes gasoline comparable to a 250 cc motorcycle, which is not as archaic as a 2-stroke engine that is ancient in design.
Owner reviews
Actually a normal moped, considering the price, but there are a lot of minor problems with quality. Plastic can be broken with your hands, iron is also not a fountain, all the brackets clearly use some kind of incomprehensible silumin alloy, clearly not designed for heavy loads. The frame itself is also fragile, I know a man whose frame simply cracked when he was driving along a dirt road in the village with a heavy passenger. I didn’t have this, but the front wing mounts fell off twice over the summer until they were welded tightly. The CVT is still a bit dull, but you get used to it quickly. Andrey, Mednogorsk.
I bought the scooter new in 2014, already with a 70 cc piston engine, like a little more vigorous. The guys never found fault, the piston itself is not visible, it is hidden under the plastic, although there are different stamps with the engine number on it. The maximum speed at 70cc is about 85 mph without a headwind, this is according to the speedometer, but it’s probably lying on the higher side. My consumption is about 2.5 liters per hundred, sometimes it was 3 liters. The scooter has not yet been sold, it sits in the village, and is used for its intended purpose from time to time. I don’t see any point in selling it for pennies, that’s why I left it. It always starts up after winter without any problems if the battery is charged and fresh gasoline is poured into the tank. Nikolay, Moscow.
I owned this model for two years and had mixed impressions. On the one hand, this is a really normal scooter for the price of a bicycle, what else do you need? On the other hand, constant minor breakdowns simply freeze out, then the candles die one after another for an unknown reason, then the mirror mount falls off for no reason, or something else. And I recommend pouring only synthetics into the engine, then the engine will live longer than 3-5 thousand km. It will bend quickly on mineral water, it has already been tested. Ivan, Vologda.
Specifications
This model was assembled from what was found from spare parts suppliers at the lowest prices. There is nothing modern about the scooter except its appearance, and in terms of design it is similar to its counterparts produced at the end of the last century. But we can’t deny it decent dynamics, and we won’t discount maintainability either.
Engine
The scooter received a 2-stroke air-cooled engine QJ1E40QMB-4, well known to all motorcycle mechanics who work with equipment from the Middle Kingdom - this motor is installed on many models from different manufacturers. It has a shorter lifespan compared to 4-stroke models, but has good performance, producing as much as 5 hp. at 49.9 cu. see volume. You shouldn’t expect much agility from it, but it provides good dynamics by the standards of the moped class, accelerating the bike to a maximum speed of almost 70 km/h according to the speedometer. Torque – 3.5 Nm at 3400 rpm.
Transmission
The most common variator, slightly “braking”, but quite reliable. This unit usually does not require the owner’s attention, especially if it is maintained according to the manual. It works quite noisily, and when picking up speed it emits a low hum, which, if you’re not used to it, can even make you think about some kind of malfunction, but in reality there’s nothing wrong with it.
Chassis and brakes
The front wheel has a brake disc with a simple single-piston caliper, the rear wheel has a classic drum mechanism, which has not changed for the last 50-60 years, and is of little use. However, the front brake works satisfactorily, and this somewhat corrects the situation. The same cannot be said about the suspensions - on uneven road surfaces it seems that the scooter does not have them at all, and every pebble on the road is fully felt by the fifth point. You can, of course, change the shock absorbers to more efficient ones, but the costs will be disproportionately high compared to the price of the moped itself.
Electronics
An ordinary generator, a 12-volt low-capacity battery, lighting equipment and, perhaps, that’s all. Electronics in Stealth Vortex 50 are no more complicated than in some “Vyatka” or “Voskhod”. Considering the low quality of many small parts made in China, this is for the better - the simpler the design, the less chance of unexpected breakdowns and malfunctions.
Weight and dimensions
The Stels Vortex 50 weighs less than 100 kg (just over 97), comparable to hundreds of other similar lightweight bikes. Physically, any driver, even the most inexperienced, can handle it, and you can store it in the corner of the garage; it won’t take up much space. The length and width at the extreme points do not exceed 183 and 69 cm, respectively, and thanks to this compactness, this scooter is an excellent tool for cutting through city traffic jams.
Controllability
The scooter handles excellently, and its short wheelbase plays into its favor. But due to the small-diameter wheels, it is sensitive to the quality of the road surface, and on bad asphalt you constantly have to “catch” the steering wheel in order to prevent it from leaving the trajectory of movement. The turning radius is small, not much longer than the length of the bike itself.
Fuel consumption
Two-stroke engines, designed using advanced technologies from half a century ago, have never been particularly economical. So the Stealth Vortex 50 shamelessly consumes 2.5 liters of gasoline per 100 km, sometimes even more. The quality and octane number of the fuel do not matter; it can run on any gasoline, but you will have to refuel often - the tank volume does not exceed 5.2 liters.
How to set the ignition on a scooter
With minimal experience, but good theoretical knowledge, you can set the ignition yourself. To do this, you just need to strictly follow the instructions below.
The most important part of tuning is to find the correct position for the timing sprocket to sit. In order to find it, they use special marks that are applied at the factory when assembling the engine.
The desired mark looks like the letter "T". In this position, the piston is at dead center. This is the extreme position after which the piston will return back. You need to rotate the rotor until the protrusion on the crankcase and the letter “T” coincide. This can be done using your hands or a kick starter. An electric starter does not need to be used.
To adjust, you need to align the “T” mark and the protrusion on the engine crankcase
Labels may look different on different scooters
If the piston has only moved down minimally, turn it further until the marks line up. It's not always possible to get the right position the first time. After they match, you need to study the other marks: they are located on the timing star. Usually these are three points or holes that are located on the outside of the star. They form a triangular shape if you connect them visually
Notice that one point is larger than the others. After adjusting the ignition, it should be on top, and the other two marks should remain opposite each other
They must stand horizontally.
Markings on the timing star
If the ignition is contactless, it is adjusted as follows. In order for the engine to run smoothly and correctly, you need to adjust the ignition of the mixture at the right moment. To do this, after all the tags are installed in the right places, you need to understand how the contactless principle works in general.
A special feature of the BZS is the presence of special sensors, a switch, and two types of ignition coil winding. When the sensor is closed using a rotor equipped with a magnet, a pulse is generated that enters the commutator, it pumps up the current coming from the generator and directs it to the primary winding of the coil. After this, the charge enters the secondary winding, where a high voltage is generated, with the help of which a spark appears, used to detonate the gasoline mixture. Adjusting the ignition is the alignment of the marks on the crankcase and the star. Usually you have to remove the valve cover.
After this you need to do the following:
- Labels are set in the manner described above.
- In order to set the ignition angle, you can release the stator mount and adjust it in accordance with the technical requirements of your vehicle.
- Make sure that the marks or holes are in the correct position.
Adjusting the fuel level
The float chamber allows you to have a constant flow of fuel in the carburetor, which is always replenished, but it is important to remember that you cannot have an excess of gasoline in the float chamber. Gasoline is drained using a special hose coming from the chamber; you will have to check the amount of fuel with the engine running. Raise the hose above the carburetor as shown in the picture below and check the fuel level. It should not differ much from the mark indicated in the picture. There is a holder antenna located on the needle inside the float chamber; it can be used to regulate the amount of fuel inside the float chamber.
Please also take into account the fact that before adjusting the carburetor, you should only have high-quality gasoline with a normal octane number. Otherwise, you will have to completely drain the bad gasoline not only from the gas tank, but also from the float chamber; it must have a special drain screw.
Advantages and disadvantages
Among the advantages of the Stealth Skif 50 scooter are:
- high power indicator;
- wide comfortable seat;
- many compartments for luggage;
- the opportunity to purchase equipment with an addition as a security alarm;
- high-quality assembly and excellent design;
- low fuel consumption;
- affordable price (from 30,000 rubles).
This scooter also has the ability to tune maximum speed, engine traction and reduce fuel consumption, if necessary.
Flaws:
- sometimes you come across defective models;
- may be inconvenient to use for tall people;
- small wheels;
- possible fragile bonding of joints.
The Skif scooter is convenient and unpretentious to use.
Unfortunately, the disadvantages of the Skif scooter scare away many potential buyers who do not want to take risks
But you just have to pay enough attention to all aspects and details when purchasing, so that you can then enjoy riding a good and high-quality scooter for your own pleasure.
The principle of operation of ignition in a 4-stroke scooter engine
Modern scooters are equipped with contactless systems. They are considered the most reliable and easy to use, do not require complex connections, and provide a constant good spark on time. However, the setting is still important; even the presence of a spark does not always allow the fuel mixture to ignite, since its power also plays a role.
The main reasons for the operation of the ignition system are quite simple: its task is to create a spark to detonate the fuel mixture. If this does not happen, you need to carefully examine each node and find out why the spark disappeared.
Broken ignition is the cause of engine failure
An incorrectly configured or faulty ignition often causes engine failure. It would be wrong to immediately climb into the cylinder and examine the insides of the scooter, especially since this will not solve the problem. Before touching the ignition system, you need to check for other reasons why the scooter may not work.
Idle speed adjustment
Does your scooter not work properly when idle and often stalls? Most likely your idle speed screw is not adjusted sufficiently. Before the procedure, be sure to warm up the engine, then find the idle screw, which is present on absolutely all scooters. You will have to warm up the scooter for 10-15 minutes, this will allow you to achieve optimal engine performance.
After this, you need to turn the idle speed screw, where clockwise rotation increases the speed, and unscrewing it decreases it.
Technical indicators
The skif 50 model from stels has impressive technical characteristics, which are worth paying attention to before purchasing equipment:
To begin with, it is necessary to note the small size and weight of the scooter, thanks to which women and even teenagers can operate the equipment. The small dimensions of the model allow you to move comfortably and safely in dense city traffic.
The 50 cc two-stroke engine can produce up to 5 hp for the driver. pp., which is quite suitable for novice drivers. A reliable suspension with sufficient travel will not let the scooterist down even when driving on country roads. Disc and drum brakes, which give confidence in control, can balance out the lack of driving skills. Despite the low maximum speed (up to 60 km/h), the scooter has good dynamic performance.

Disadvantages of the model
The ease of control makes the stealth tactic scooter an excellent option for a teenager. Good handling, attractive appearance, and an interesting dashboard increase the popularity of the scooter. Reviews about stels tactic 50 are contradictory. While it’s new, there are no problems as such, but as soon as you drive 1000-2000 km, interesting moments begin.
Perhaps many have problems with incorrect running-in or manufacturing defects, but stealth tactics are short-lived, even compared to pure “Chinese” ones. In general, the characteristics of the stels tactic 50 correspond to its price.
Broken ignition as a cause of engine failure
First of all, I would like to talk about what can cause a four-stroke scooter engine to fail, and whether misconfigured ignition should be blamed for this. Answering this question, we can answer with one hundred percent confidence that an incorrectly configured or simply faulty ignition may well become the cause of engine failure. However, it is too early to blame everything on a faulty ignition system until you check the main parts that affect the performance of the engine. Let's talk about them in more detail.
The first and perhaps most obvious is a lack of fuel or a clogged carburetor. Before you start trying to adjust the ignition, thoroughly clean the carburetor and make sure that fuel is flowing to the engine. Also, check that the carburetor is providing sufficient air supply.
The second, most common reason why an engine refuses to start is faulty spark plugs. Make sure that the spark plugs used in the scooter are not punctured and have a good enough spark. Simply replacing the spark plugs usually helps.
If you are completely convinced that there are no more reasons for the engine not to start, then you can dig deeper and look for the problem in an incorrectly configured ignition. Let's figure out how to set the ignition on a scooter.
Advantages and disadvantages
Comparing the Stels Tactic 50 with other similar scooters, it is difficult to identify any distinct strengths or weaknesses. But we’ll still try, although this is just another extremely budget moped, the whole purpose of which is to carry its owner and, if possible, not cause him problems.
Advantages
- A small mass, not reaching even a hundred kilograms.
- Very low price of both the scooter itself and all spare parts for it.
- Abundance of available tuning.
- Economical and low maintenance costs.
- Simplicity and maintainability.
Flaws
- Low service life of a two-stroke engine.
- Small gas tank volume.
- Low quality plastic, which can crack not only from a fall, but also from vibrations or driving on uneven roads.
Similar models
- Motoland F22 . An inexpensive 4-stroke model sold in Russia under the auspices of a popular brand.
- Honling Priboy 50 . An extremely budget scooter with forced engine cooling costs only about 30 thousand.
- Racer Meteor 50 . A budget bike, economical and very light - weighs less than 80 kg.
Repair and tuning
Maintainability and low cost of spare parts are characteristic of almost all Chinese motorcycles. In addition, it is a good place to practice your first repair skills, which may come in handy sooner or later. It’s better to practice on something budget-friendly, and the hero of our review is perfect for this role.
Repair
Anyone can repair the Tactic 50 themselves. If you've seen the inside of at least one budget scooter, then you've seen them all, because they have minimal differences. Forget about special tools and so on, for any service and repair operations, a standard set of tools will be enough for you, the most complex of which will be a regular torque wrench with adjustable torque. And then only if you get into the depths of the engine.
Spare parts
This model, like many others, was assembled from components used by various Chinese motorcycle manufacturers. Therefore, there are no problems with spare parts, and there is no need to contact dealer stores - everything you need can be picked up from other scooters. Spare parts are cheap, and you can buy everything you need, even a new engine or a complete set of plastic. The prices will definitely please budget-conscious bikers.
Tuning
Usually, all tuning of cheap Chinese bikes comes down to minor decoration, but the popularity of the model has made its own adjustments here. Since all the components from which the Stels Tactic 50 is assembled are used on other models, they are widely used. Therefore, a lot of things are suitable for this scooter, and many owners change the piston by installing a larger-volume CPG. You can even buy such tuning on Aliexpress, and many dealers at one time sold bikes with a new piston, although according to the documents they remained 50 cc.
Setting the mixture quality
The quality of the mixture plays a key role in the operation of the entire scooter, because incorrectly configured parameters will lead to the scooter choking, consuming a lot of fuel and increasing wear on the piston group. That is why the combustible mixture must be in the optimal quantity; a lean mixture indicates a loss of power and frequent overheating of the engine, a rich mixture is characterized by high fuel consumption and the presence of heavy carbon deposits in the combustion chamber.
There are two ways to adjust the quality of the mixture - with an adjusting screw or the needle level in the damper. In some cases, the carburetor design assumes the absence of an adjusting screw, so adjustment is carried out only with a needle. The standard procedure for adjusting the screw is to rotate counterclockwise and clockwise; in the first case, the mixture becomes lean; tightening the screw indicates that the mixture is richer. In the case of a needle, you can enrich the mixture by raising it up; the lean mixture is set on a lowered needle.
Important: adjusting the quality of the mixture should also be carried out with the engine warmed up for 10-15 minutes.
The instructions for most scooters say that there is a standard setting for the mixture quality, where the screw should be unscrewed only 1.5-2 turns. Therefore, if it is impossible to accurately adjust the mixture, stick to this indicator.
The needle is adjusted by raising or lowering it; it has markings and a special locking ring that sets the current height. Accordingly, if you find a lean mixture, you will have to raise the ring level by 1 notch. Having achieved optimal performance, your scooter will operate smoothly and correctly, it will consume fuel in normal quantities, and the power will correspond to the characteristics.
Scooter owners sooner or later encounter poor performance of their “iron horse”. The reasons can be completely different, one of which is a problem with the scooter’s carburetor. In this case, it is necessary to disassemble the carburetor, clean it and readjust it. Further in the article we will tell you how you can adjust the carburetor of the Stealth Tactic 50 scooter. Looking ahead, it is necessary to say the following: adjusting the carburetor with your own hands is more than possible. To do this, you need to be familiar with the structure of the carburetor and the principle of its operation. If difficulties arise during the disassembly process, you can always turn to specialists for help who will do everything in the best possible way.
So, let's begin. The needle located in the air damper should not move over a wide range. It is best to move such a needle with a corkscrew ring, which must be placed in the grooves. We insert the ring into the middle groove, then fully tighten the bolt responsible for the quality of the mixture and unscrew it a quarter turn. Next, we start the engine. We listen carefully to the operation of the engine. If the idle speed is not stable and is higher or lower than optimal, it is necessary to adjust the screw responsible for idle speed.
After this, you need to bring the idle speed to maximum using the screw responsible for the quality of the mixture. Done? – loosen by ½ turn. If everything is done according to the instructions, everything should be fine. We check the work done: we set off and pick up speed. If there are no failures in engine operation, then everything was done correctly. But, if there are so-called “dips,” it is necessary to tighten the screw another ¼ turn. Be sure to adjust the idle speed screw after fine-tuning the quality screw.
Repair and tuning
What made Chinese scooters so popular was not their quality, but their cheapness and abundance of available parts. All of them, to one degree or another, are “constructors” in which you can replace anything you want, and it will not cost much.
Repair
Even an inexperienced but diligent motorcycle mechanic will be able to perform any service operations. The design of the brainchild of the Chinese-Russian company is as simple as three kopecks, and almost everything can be repaired in it. And what cannot be repaired can always be replaced by selecting the necessary part from some other similar scooter, fortunately, the unification of spare parts among Chinese manufacturers is enormous.
Manual
If you purchased this model of scooter from Stels and you are interested in the details of its proper operation, then you should carefully study the instructions that the seller must provide you with the product.
The Stels Skif 50 model is very easy to use
If not, then some of the most important aspects will be discussed below:
- First of all, you should follow the traffic rules. Be sure to wear a protective helmet and gloves. You should operate the scooter with both hands and keep your feet on the footrests.
- Full concentration is strongly recommended during movement to avoid injury.
- While driving, keep your right hand on the throttle grip and your left hand on the left grip.
- When transporting things on the trunk, they should be carefully secured. Carrying heavy loads is strongly discouraged to avoid injury and fines.
- To maintain the scooter in optimal condition, you should check it regularly: after long-term parking, when operating in rainy and dusty weather. It is recommended to check the scooter at least twice a season in a special service workshop.
- You should wash the scooter yourself only after the engine has completely cooled down. This should be done with a sponge and a special vehicle cleaner. Polishing should be done with polishes that match the color.
The Stels Skif 50 model is highly maneuverable
- Before storing equipment for a long time, you need to thoroughly wash and dry it, fill the tank with gasoline and stabilizer. Then you need to let the engine run for about 10 minutes and drain the fuel from the carburetor. Then disconnect the battery and plug the exhaust pipe with a rag, coat all parts with a wax-based preservative and cover the scooter with a special cover.
- Do not start the engine without connecting the battery properly as this may damage some electrical components.
- For questions regarding warranty and post-warranty repairs and maintenance, please contact the company where you purchased the scooter.
Battery
You should check the electrolyte level in the battery every 1000 km. Exceptions include maintenance-free batteries. On the lid of these it will be written: “DO NOT OPEN”.
To check the battery, you first need to remove it. To do this, you need to open the battery compartment cover and disconnect the positive and negative contacts. Then check the electrolyte level and add distilled water if necessary. When reassembling, the positive contact is connected first, and then the negative one.
Most spare parts can be found in service centers
Wiring
Let's briefly look at the operating features of the Stels Skif 50 CPG. When the engine is running, a large load is placed on the cylinder. Chemical energy is released, but only a small part of it is converted into mechanical work. Most of the remaining heat is removed by cooling air created by the cylinder fins. These fins must be kept clean to avoid thermal insulation of the cylinder, causing the piston and the cylinder itself to become deformed.
In completely new engines, the piston in the cylinder is likely to scuff. For engines that have undergone appropriate tuning, there may be a gap between the cylinder and the piston.
Such clearances are checked during special tests of prototype engines.
The temperature of the piston is not the same during engine operation, so its shape is adjusted solely to avoid various types of deformation. After all, at maximum thermal load the piston expands, but there must be a working gap between it and the cylinder.
At a fairly low and affordable price you can purchase spare parts for Stels Skif 50
In order to check the Stels Skif 50 starter relay, you must first disconnect the red and white motor wire. Next, turn the scooter's ignition switch and squeeze the brake lever. Press the starter button and check the continuity of the circuit; it should not be broken.
Pros and cons of technology
The skif 50 scooter has both advantages and disadvantages that you need to keep in mind before purchasing. The advantages of the model include:
- High-quality assembly.
- Reliability of the suspension and braking system.
- Low cost (from 20 to 50 thousand rubles depending on mileage).
- Stylish design.
- Spacious luggage compartments.
- The presence of a security alarm as standard.
- Availability and low price of spare parts.
- Good load capacity.
- Comfortable fit.
The scooter also has its disadvantages. For example:
- It is not very convenient for people of great height and impressive build to move around on it.
- Fairly high fuel consumption.
- You come across poorly assembled scooters, which after 6–12 months begin to develop various breakdowns (from failure of the throttle handle to noise from the brakes).
In conclusion, it is worth saying that the Stealth Skif 50 can be a good replacement for more expensive scooters with mileage. However, it’s up to you to decide what to choose – a used Honda Dio or a new skiff.
Review of the STELS Tactic 50 scooter
Of course, the STELS Tactic 50 scooter will also be appreciated by representatives of the older generation
It has quite adult dimensions and good technical characteristics, which will certainly attract the attention of all lovers of motorized two-wheeled vehicles. However, a motor scooter is especially attractive as a gift for a child.
A scooter is a wonderful gift that encourages a teenager to be more attentive, responsible, and can also satisfy and stimulate a craving for technology.
Unlike its predecessor Skif 50, in the Velomotors scooter line, the STELS Tactic 50 is equipped with a more powerful engine: the maximum power of 2.9 horsepower at 5500 rpm is 60% higher than that of the Skif 50, and the maximum torque is 3. 5 rpm In addition, the STELS Tactic 50 has large dimensions - 1.8 x 0.7 x 1.1 m, the saddle height is 75 cm, and the wheelbase is 1.27 m. The manufacturer has equipped the scooter with wider tires: the front and rear tires have width 120 and 130 mm respectively. In general, the scooter was more powerful, larger and heavier (92 kg).
Otherwise, the scooter has standard characteristics: carburetor power system, contactless ignition system with CDI electronic control, CVT transmission, two-stage spur gearbox, front disc and rear drum brakes, automatic gear shift mode. The maximum speed is 55 km/h. In general, the two-wheeled vehicle combines reliability and excellent driving characteristics, which allow you to plan trips over long distances. A luggage rack for small items is included.
We should also highlight the nice design and electronic components. The scooter's dashboard has an LCD monitor that displays traffic information, including missed calls and received cell phone text messages. A very relevant function for young people who want to always stay in touch. You can add the included sports muffler to the design treasury, and in favor of electronics, you can add an alarm system to control the engine start from a distance.
Trips to the sea, moving around the city, to a suburban dacha - for all this the STELS Tactic 50 is perfect. You can be sure that your children will also enjoy the versatile features of this scooter.

FAQ
- Everyone says that two-stroke engines have low engine life. Approximately what? On average, according to owner reviews, for this model it exceeds 10,000 km. Replacing the piston with a new one is inexpensive.
- Do you need to fill it with gasoline already mixed with oil, like in a Soviet motorcycle? No, the oil is poured into a separate tank, from where it gradually enters the combustible mixture in the required quantities.
- I'm going to change the CPG to a new one, I want to plug it into 100 cc, will I need to run it in again? Yes, but not as hard as at first, since the engine has been broken in for a long time. But for the first 500-700 km it is better to drive at a moderate speed, without high revs, and after the break-in is completed, you need to change the oil again.
