Paris Show: BMW to launch Supersport HP2

Madder Megamoto for 2008


THIS is BMW's Supersport HP2, yes BMW's HP2 Megamoto is set to get even sportier for 2008.

The machine, which is based around BMW's HP2 competiton trailbike, is to feature a carbon subframe, Brembo Monobloc calipers, digital MotoGP-style dash and even a quick shifter.

This, along with BMW's commitment to competing in 2009's World Superbike series, shows the company are determined to shake off their middle-aged mantle.

Technically, the BMW HP2 Sport is based on the BMW R 1200 S. The most striking difference of the BMW HP2 Sport from the endurance racing Boxer is the brand new cylinder heads: Each of the double overhead camshafts (DOHC) uses a drag lever to actuate the valves that are larger than in the BMW R 1200 S. Further modifications such as the flow-optimised intake and outlet, new forged pistons and adapted connecting rod help the engine to achieve the necessary higher output compared to the basic engine.

The new stainless steel exhaust system is placed below the engine for the first

time. This keeps the construction of the lower area of the motorcycle extremely

slim, enabling great freedom of movement for the familiar 'hanging off' riding

BMW have used a quickshifter together with the narrow ratios of the 5-speed gearbox to enable fast gear changes without having to ease off the gas and operate the clutch. In order to adapt the gearshift pattern for the racing circuit, a suitable replacement pressure sensor is available as special equipment if necessary.

The fully adjustable Öhlins sports chassis also has a Brembo monoblock brake

system with radially mounted, four-piston fixed calipers at the front.

Optimum ergonomics are ensured by the adjustable forged aluminium

footrests, the adjustable stock handlebar and the Magura radial manual buttons.

The series dashboard that comes directly from MotoGP sport provides the

rider with important information and can also deliver lap times plus other racing

relevant data as well as the usual displays.

BMW claim attention was paid consistently to the lightweight construction of all components. This includes not only the self-supporting front fairing and the likewise self-supporting carbon rear or the weight-optimised forged wheels, but also hidden details such as the lightweight generator.
