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.
