Presented in the autumn of 1973 at the Paris Motor Show, the BMW R 90 S was marketed in Italy from the first weeks of the following year. It is a real spaceship, full of innovative solutions, superb and fast compared to the classic boxers of the Teutonic House. In Italy, in 1974, the German maxi cost even 2 million and 400,000 lire, far more than the contemporary 900 cc of other brands. The BMW R90 S represents the maximum evolution, in terms of power and sportiness, of the multi-year twin-cylinder boxer signed BMW. The hand-shaded painting, from silver gray to black or from the same gray to orange (Daytona Orange), a color very popular in Germany at the time, is something divine: without being blasphemous, we wanted to represent the non plus ultra of new with respect to the extreme and classic fixity of the colors of the two BMW wheels.
DOUBLE DISC BRAKING 67 HORSES The BMW R 90 S was full of innovations compared to previous versions, such as: the introduction of the standard double front disc, the 5-speed gearbox a bit 'hard, but with the left , Dell'Orto carburettors and instrumentation (complete with speedometer speedometer, rev counter, electric clock, voltmeter and five colored lights) embedded in a crop and aerodynamic fairing, matching the superstructures, integral with the fork, equipped with a plexiglass anti-reflective, but not suitable for sports use of the motorcycle. The two-cylinder boxer engine of the powerful Bavarian motorcycle, able to develop a power of 67 bhp at 7,000 rpm, has changed slightly compared to that of the previous R75: only the bore in fact went to 90 mm, while the race remained from 70.6 mm. For the first time in the history of the Bavarian House, the R90 S is equipped with two Italian carburettors Dell'Orto PMH 38, no doubt more valid than the classic Bing vacuum; another important innovation is the hydraulic steering damper, adjustable on two load positions. The braking system instead sees two 264 mm front discs, bitten by a pair of Ate floating calipers, while at the rear a simple 200 mm central cam drum slows down the stroke of the bike acting on the spoked rim; the pump-tank system for the front brake fluid is located under the tank, behind the steering tube and not, as with most of the motorcycles on the market, on the right side of the handlebar. Particularly the tapered tail, remained unknown until the presentation of the "shaded thunderbolt", and located behind the comfortable saddle, inside which a compartment was built to accommodate objects useful for the motorcycle and the centaur.
The driveability of the two wheels is more than satisfactory: the bike is pleasant in the corners, which are faced with confidence even at high speeds; the handling of the vehicle is mainly due to its low center of gravity and its extraordinary power is available at any speed, with the scarcity of any type of vibration from 1,000 revolutions upwards. The engine, easy to start, is silent, as are the discharges, its minimum is very smooth and the engine brake is very efficient. The two liveries of the bike were painted entirely by hand, so the main feature of the BMW R90 S is recognizable in the fact that there are no two identical R90 S in the world: this makes the owners of this model proud because each of them has a unique piece . To define it as a dream is nothing short of.
Collectors today look for it like gold: the important thing is that it has the plate and the original documents and that it is perfectly preserved. And it is no coincidence that in Monaco when they commissioned Roland Sands to create the Concept Ninety to celebrate the twentieth anniversary of the propeller, they took two birds with one stone, celebrating the forty years of the R 90 S, taking the coloring and the writing on the engine. The elegance of the R90 S, its antique flavor and its scent of innovation make the BMW maxi-sports a complete motorcycle and much appreciated all over the world: its comfort in the gran-tourist routes remains undisputed, just like its engine, boxer since 1923.
