BMW K 1100 RS from home workshop

R 1100 S

- motorcycle model, BMW brand

The most popular motorcycle of all produced by BMW is the BMW R1100S. When compared with sports models from other world-class manufacturers, this model is more like a sports touring motorcycle. The R11OOS engine is installed. This is a souped-up version of BMW's beloved boxer engine. Maximum power – 96 HP.

The gearbox transmits torque to the rear wheel via a closed driveshaft. Suspension – Paralever and Telelever feature lighter, improved components such as front and rear monoshock absorbers.

The center of the frame's power circuit is the engine block with gearbox. Brembo brake systems are integrated into the Evo braking system. It is possible to connect ABS. The manufacturer offers sporty suspension components and a wider rear wheel.

The BMW R 1100 S sports motorcycle is distinguished by its athletic stance with the appearance of an athlete, and a powerful engine. Successfully tested at the Hockenheim Motordrome and on the serpentine roads of the Dolomites, it showed a confident ride and ease of handling, thanks to the combination of the latest technologies in the suspension.

The BMW R 1100 S motorcycle is reliable and durable, a real winner, capable of conquering everyone with its sporty ride. This stunning sport-touring motorcycle from BMW will open up new horizons and sporty boundaries whether riding alone or with a partner, on short jaunts or long journeys.

The R 1100 S is the sportiest motorcycle BMW makes, but if you compare it with sports cars from other manufacturers, it is more of a sports tourer. The powerful boxer engine of the R 1100 S is a boosted version and accelerates to 72 kW, equivalent to 96 hp.

The motorcycle is equipped with a 6-speed gearbox, the torque from which is transmitted directly to the rear wheel using a closed driveshaft. The front and rear suspensions are equipped with lightweight components. The frame of the R 1100 S has three parts, and part of the power circuit is the engine-box unit. The Evo's braking system includes Brembo modules, and it is also possible to install ABS. At the request of the client, it is possible to equip the motorcycle with a wider rear wheel, as well as sports suspension components. The R 1100 S has an attractive, sporty appearance.

The semi-fairing smoothly transitions into the lining of the gas tank, and then into the wide tail fairing. Unfortunately, due to the design features of the boxer engine, the motorcycle has less ground clearance when cornering. The cylinder heads are visible on the sides of the R 1100 S, and therefore when riding on a track, the motorcycle can touch the road when cornering. To avoid this situation, carbon fiber sliders are installed on the racing versions of the car, which protect the cylinder heads from mechanical defects, and the suspension is slightly changed. To demonstrate the sporty style of the R 1100 S, BMW regularly holds racing competitions called the “BoxerCup”. In addition to many famous athletes, Kevin Schwantz, a former Grand Prix racer, and Brian Morrison, a former participant in World Endurance, take part in them.

Powerful tourer BMW R 1100

A touring motorcycle with a two-cylinder boxer engine is the BMW R 1100 RT. Produced from 1996 to 2001 by the BMW plant (Spandau) along with several similar designs, including the R1100R and R1100RS, with almost identical engines but different trim parts.

After the R100RT, the R1100RT was released in 1996. In addition to the extensive changes, engine power increased significantly from 44 to 66 kW (60 to 90 hp) and displacement increased to 1,085 cc. cm.

In addition, the new BMW has the following characteristics:

• has a bore of 99 mm, stroke of 70.5 mm;
• compression ratio 10.7:1;
• maximum speed 211 km/h;
• acceleration time from 0 to 100 km/h is 3.9 seconds.

The BMW R 1100 gs is equipped with an anti-lock braking system and an adjustable three-way catalytic converter. The chassis is designed in three parts and consists of a front and rear frame and a cooperating geared motor ligand. The fuel tank holds 25.2 liters. Average fuel consumption is 4.7 liters per 100 km at 90 km/h or 5.6 liters at 120 km/h.

It is recommended to use gasoline with a knock resistance of at least 95 octane. The front tires are 120/70 ZR 17 and the rear 160/60 ZR 18. The motorcycle weighs 285 kg when running and has a maximum additional payload of 205 kg.

Models and competitors of the BMW R 1100

Touring motorcycles with comparable equipment and engine performance are the Honda Pan-European, Honda Gold Wing and Triumph Trophy 1200. The BMW R90S bahnstormer offspring arrived, appearing in century trim as the new R1100S. The 1993 S is the most powerful BMW Twin ever built.

Advantages

BMW's new model isn't intended to be a pure sportsbike, but the shell of the 1100S is an improvement. Provided that the basic tuning has not changed. Main advantages:

• less weight;
• more power;
• crisper steering;
• with a more sophisticated design.

BMW unveiled the 1100 at the end of June, coinciding with the opening of the Art of the Motorcycle exhibition at the Guggenheim Museum in New York. Engine BMW R1100S 1085 cc cm, air/oil cooled, four valves vs Twin. Forged pistons have higher compression with a 2mm thick top dome.

Forged pistons allow the redline to rise to 8,400 rpm from 7,900 rpm, while a vane air filter and redesigned intake duct improve airflow. The new stainless steel exhaust with integrated catalytic converter provides 70 percent of the power.

The new BMW R 1100 RS has 80 horsepower. Peak torque up to 200 rpm. The Bosch Motronic fuel injection engine management software has been recalibrated. oil pump capacity 350 cc. cm prepared to handle additional thermal loads. Magnesium valves and an alternator help keep the engine running, connected via a new hydraulic clutch to a much smoother six-speed transmission.

Reviews of the BMW R 1100 operation

Nikolay, 38 years old: “The unique A-arm front suspension of the BMW R 1100 S is attached to a new aluminum alloy frame, and the front suspension components are lightened. Machined (instead of cast) slider tubes give the S a unique look.

The new monotube gas shock serves as a Telelever damper, allowing only rebound correction. The single rear shock has 40-position preload spring adjustment as well as rebound adjustment. The steering geometry has sped up slightly. The steering wheel angle has increased by 1 degree. Such criteria allow you to use the motorcycle in any case and if necessary. The model is improved, but personal tuning is possible.”

Vasily, 41 years old: “I bought a motorcycle for myself. Good transmission, great cast spoke wheels from a K-bike. Dual 305mm front brake rotors lock directly onto the rim spokes and are clamped by four Brembo piston calipers. The model is practical to use and reliable. Moving over uneven and hard-to-reach places is now not at all difficult.”

Marek Kruszynski and his BMW K 1100 RS

Marek Kruszynski, a resident of New York City, New York State, recently wanted to feel the wind of the local roads again, and instead of just paying for a purchase at a dealership, he decided to create a motorcycle that he would want to ride. Marek, a long-time fan of the Bavarian brand, had not ridden motorcycles for more than 20 years, but then he took a BMW K 1100 RS and turned it into a real work of art in a small home workshop.

I was watching Racer TV on YouTube and there was a video about a BMW K 100 with horizontal suspension from Retro Rides. And I realized - this is it! “I bought the Cafe Racer Bible from Lourenco Brothers that evening and started collecting information,” Marek says.

The project was planned without much haste, with pleasure and maximum attention to detail. And since real estate would cost a pretty penny in New York City, Marek worked on his motorcycle “in the cozy garage of a farmhouse upstate in the Catskills.”

Custom BMW K 1100 RS

The basis of the project, a 1993 K 1100 RS, was purchased with a full bonnet and in good external condition, despite being almost 30 years old. This is quite a big girl - 270 kilograms, after all, and Marek began by stripping her of the excess, then examining every screw, saving what was suitable for her new life and pushing everything else away.

Hello again. A little unusual role for me, but since everyone is writing, then why don’t I go into fiction, otherwise all the boards and circuits are there) In this post I will try to describe in as much detail as possible the result of the search for an elderly BMW 1100-1150 series, and also the work that needs to be done with it and the cost of spare parts. I hope this is useful to someone. I’ll warn you right away - there are few photos, a lot of words.

So, the last motorcycle was damaged)) And since I still wanted to change the class of the motorcycle, I sold it as is, taking into account the discount for restoration. The process of choosing a new motorcycle was far from the easiest. Firstly, my performance characteristics do not allow me to roam around, since with a height of 197 cm, the motorcycle cannot be small by definition. As well as small-capacity ones. And the main use in traffic conditions in Moscow imposes its own restrictions on the class of the motorcycle and its dimensions. Yes, I myself have seen drivers of cruisers and goldwings, whom I had difficulty keeping up with in a traffic jam in my TDM, but apparently I don’t have such talent, and the result of last season additionally put my brains in place in terms of the fact that you need to be able to drive) But That’s not what this post is about... So what is this about? Oh yes, choosing a new motorcycle... This is where the most problems arose. I just didn’t know what I wanted to ride, nothing attracted me. The most important point was the presence of an anti-lock braking system (ABS), since it was the locking of the front wheel in an extreme situation that turned the proud motorcyclist into a sliding creature, albeit a very fast sliding one. By the way, I slipped into a BMW GT. It's just fate.

It would seem that we go to a well-known website, set a price limit, the availability of ABS, and choose... So we didn’t like anything - even something that was beyond the budget. I was thinking about looking at the 900th TDM (unlike mine, which already has an injection system and the presence of ABS) - but it is generally the same as the 850th - the point is to take the same thing.

Cruisers, no matter how much I like them, are not as comfortable in the city as classics and tourists. Geese are prohibitively expensive (all other things being equal, with their counterparts from the BMW R, RS, and even RT - GS series they cost 30 percent more, despite the fact that the cheapest options are literally dead).

Then I remembered that at one time I really liked the BMW R1100R - and it was the 1100s, since the 1150, may the owners and fans forgive me, I did not like in appearance. But after looking at several options both in showrooms and from private owners, I realized that they are also quite tired and will require significant investments.

We are looking further - although we are already choosing from the BMW R1100 and R1150 series, RS and RT series. Moreover, priority on 1100 is not the first, but the second generation of ABS, but, unlike models with servos (1150 and 1200), it is not so delicate and breakable. There is nothing to say about the injector - in terms of equipment, motorcycles from Bavaria have long become trendsetters in technical terms. And here it’s almost like a tube, warm))) And the 1100 series from the Bavarians is almost all the same - small differences in the suspension and body kit - to simplify, these are all 1100 geese, only with different plastic. Yes, the landing is different, and the legs are bent differently - but the base is the same for the entire series. “And that’s good” ©. And as experienced people also told me, back then they didn’t cut everything that was possible.

So, I'm looking for an R1100RT or R1100RT. Since I often ride a motorcycle to the country, the priority was to search for an RT-shki, as it has truly excellent wind protection. But all the models that I looked at in showrooms - or rather 8 pieces, with all the advantages described by the sellers, when checking the auction sheets - turned out to be rubbish on two wheels.

I remember 2 white RT-hi in one of the salons on the Moscow Ring Road. Both are 1996-1998, both have mileage in the region of 50,000, I found auction sheets - not a single 3, average 4. Well, I think it’s super, and I’ll definitely pick up two nearby. I come and look...

Subject No. 1 - the saddle is all torn, as if a bull terrier with teething teeth was put there. The seller says: “If you know, then they had this disease...”. The cardan play in both planes is such that a knock can even be heard. The cardan bites at 3 points. The plastic gaps are uneven all around, there is no plow, the front discs can be used as a rattle.

Subject No. 2 - everything is about the same, only there is no mirror, but there is a plow, and the village is intact, despite the disease. Both are sweating oil as if they decided to lose weight - where there is no plow, they apparently wash the floor, but the second one revealed himself as a puddle in plastic. In general, you understand, I went from there. In other salons the situation is no better. Private owners had only 2 devices not for sale, but the price was very high, I think they were sold at random - if they buy it, great, no - because you need such a cow yourself. And with plastic there are also a lot of worries - disassembling it for maintenance is still a lot of work, and over time the mounting ears become fragile, which makes the task even more difficult.

And then the turquoise R1100RS with white seats caught my eye. Very beautiful, I really liked it, aaaand... also killed) By the way, it is still for sale in that salon.

But I already knew what I would look for.

But PCs are a rather rare species in our country, and there wasn’t much to choose from. I was already thinking about dealing with an order from Japan, which is also a big lottery. The RTs described above had very good auction lists, but even at the BDS auction no one evaluates the technical condition of the components, only noise, smoke and oil leaks. But the same biting cardan entails the following work: replacing the cardan, replacing bearings, replacing oil seals - about 60,000 rubles in total. So think about it after that)

And by chance I find 2 PCs in one of the showrooms – a 2003 r1150rs, and a 1996 r1100rs. I didn’t even have to look for auction sheets; they were posted directly on the website. I checked for correction - everything seems to be the same as with the Japanese. I went to look. Of course, I started with the newer one. The mileage is 23,000, the ABS seems to be without errors, but there is play in the cardan - it bites in position 1 and 1 pot does not work (the injector is clogged or dead). Otherwise, everything is fine.

Version 1100 1996 - mileage 11,000 (judging by the auction sheet - confirmed), ABS gives a floating error (due to a discharged battery), condition - the fly was not sitting. The footrests are not worn out, the grips too (who knows, will understand what I mean), there are no oil leaks, the cardan has no play or snags. Moreover, no one has climbed into it yet - all the fasteners are marked. Essentially almost a new motorcycle. And yes, there is no rust - most likely garage storage in the depths of the island. In the photo below is exactly him:

In general, you should pay attention to rust - this is a very serious problem for aged equipment from Japan. As I managed to find out, they don’t drive there much, since parking is paid, and very often they store motorcycles on the street. And since there is a salty ocean around, the rate of corrosion increases significantly. Pay attention to this - fighting rust can also cost a pretty penny (examples of a motorcycle of the same year, but stored outside).

After thinking about it, I took the 1996 R1100RS. Among the found faults: the rear turn signal bracket was broken during transportation (to be replaced), cracks on both glass panels of the turn signal at the back (seal), scratches on the cylinder covers on both sides (fall on the spot, or transportation), the right corner of the fairing is frayed, there is no pedal axis rear brake, one nut on the muffler flange on the left is missing, dead battery, hazard warning button not working. This is the luggage with which I took it. As you can see - nothing terrible or critical, it would seem - change the oil and brake fluid and go ahead.

But, further into the service, and here everything became more accurate and clearer. I'm probably already tired, so I'll be brief:

• Changing the oil in the internal combustion engine, gearbox, gearbox
• Changing the oil in the fork with replacing the oil seals and boots (the oil was flaky, the oil seals and boots could be ok, but they changed it because they didn’t work anyway)
• Rewinding almost all the wiring, since all the external insulation was crumbling off at my native one (yes, this is a problem with the Germans - 2 rolls of professional rag insulating tape for harnessing wiring in engine compartments and there are no problems.)
• Cleaning and inspection of all contacts using a special liquid.
• Replacing the battery - I sold a bunch of old ones for 40 rubles/kg. And I took a new gel Exide specifically for BMW for 2300 rubles
• Replacing gaskets with a cylinder head roof - relatively inexpensive 1100 per piece
• Replacing the gaskets of the intake manifolds (manifolds) - there are no visible cracks, but at speed they suck in air and it is impossible to synchronize. Not in Moscow, ordered from England - exactly 96 euros.
• Replacing brake fluid
• Replacing brake hoses - if you install original ones made of ordinary rubber - then 5 hoses cost 18,973 rubles. Just for the hoses - I already installed reinforced hoses, I contacted the same office - crimped on special equipment, with the same angles, white reinforced hoses cost me only 5,700 rubles. Think for yourself, decide for yourself.
• Replacing tires - I drove the ancient Pirelli, the new Shinka, and the new Michelin Pilot Road 3. The choice was simple - Michelin. I searched and found a discounted set of front Pilot Road 4 and rear Road 3 for 16,000. Moreover, the front tire was made in the first week of 2017)
• Valve adjustment - on these BMWs every 10,000
• The solution to the problem with light was installing bi-xenon (6,000 rubles.)
• Synchronization.
• Replacing the clutch cable - according to information from the forums, a common problem is the separation of the boss at the end of the cable - I decided not to wait and replace it. Not a panacea, since many even have new original cables that last only six months. Let's see, the old one under the seat is used as an emergency repair
• Lubrication of all components - the motorcycle was disassembled to the ground for inspection - so we lubricated everything that was possible.

The motorcycle is still in service, the manifolds are stuck at customs, but we can already sum up the intermediate result:

• Spare parts and consumables (all together) - approx. 43,000 rubles
• Works – 34,000 rubles
• Insurance and maintenance, registration - I haven’t done it yet, the DCT and PTS are without a date, but I think I can do it within 6,000 rubles.

The motorcycle cost me 223,000 rubles; it costs another 80,000 to bring the motorcycle in very good condition upon purchase to perfect condition in reality.
The whole point is that it stood for a very long time, and most of the jambs are because of this. Many people take a BMW in similar condition, change the oil and start driving. Nothing seems to rattle, the oil is changed often - but everything gradually accumulates and falls out en masse in a very neglected state, so there have been legends about it breaking for a long time. And the prices of many spare parts are scary - but you can always find a reasonable replacement, take the same brake hoses. PS Fortunately, the delay in manifolds does not put so much pressure on the psyche and the desire to ride, since the snow outside the window advises you to stay at home with your family and be patient a little longer)

Thanks to everyone who made it through. I hope this information will be useful.
