BMW unveiles an all-new 800cc vertical-twin motorcycle, the F800S

In another break from its tradition and a further step into the mainstream of motorcycle design, BMW has introduced an all-new 900cc vertical twin, which will debut at the Milan Show in November. Developed in cooperation with Rotax and manufactured in that company's Austrian facility, the eight-valve engine uses a stout 12:1 compression ratio to make a claimed 80 horsepower. A counterbalancing scheme keeps it smooth. It has a six-speed gearbox and belt final drive. Standard BMW features such as catalyzed exhaust and optional anti-lock brakes are included on the 441 (claimed wet) bike.

BMW's press release on the new bike is below.

PUSHING INTO THE MID-RANGE: The new BMW F 800 S twin-cylinder

With its completely new mid-range sports bikes, BMW Motorrad is ringing in the next round of its model offensive. In the first half of 2006, the F 800 will be the fourth model series to come off the Berlin assembly lines and it is sure to stir up the middle class. The F 800 S is an 800-cc twin which offers lots of character, an excellent suspension and typical BMW properties.

The athletic F 800 S sports bike has a dry weight of under 419 lbs. (approx. 441 lbs. ready-to-ride) and is the first model of the new and separate model series. The precise suspension is designed for high directional and cornering stability as well as optimum handling. The classic BMW qualities such as safety, compliance with the highest environmental standards, ergonomic seating position and comfort also for the passenger define the new standard in the mid-range bike. A closed-loop three-way catalytic converter, state-of-the-art digital engine electronics and optional ABS are also a matter of course for this motorcycle.

With regard to the drive-line, BMW Motorrad is continuing with the innovation introduced on the F 650 CS and makes use of the low-maintenance and quiet-running belt-drive. It is lighter than shaft drive and represents the optimum combination of weight, space requirements, efficiency and service life in this performance class.

The engine is also a completely new design. It was developed in cooperation with Bombardier-Rotax GmbH. It is manufactured in the Austrian Rotax plant and is delivered to the Berlin production line ready-for-assembly. The first two-cylinder inline engine in the history of BMW Motorrad features a four-valve design. High 12:1 compression and a combustion chamber designed similarly to the one used in the new K-engine ensure effective and low-emission combustion, as well as efficient fuel consumption which will be considerably lower than that of the competition. Mass compensation for the crankshaft balances unwanted vibrations without foregoing the vigorous characteristics associated with two-cylinder engines. The compact engine unit with integrated 6-speed gearbox has been designed for balanced power delivery and uncomplicated riding pleasure. A peak output exceeding 80 bhp with respective torque will also satisfy a sports-rider's needs.

The new BMW F 800 S will be presented to the international press and then the public for the first time at the EICMA Motor Show in Milan on 15 November 2005.The price has not yet been set.
