The key engine data are very respectable: the engine achieves more than 96 kW/128 bhp at 8750 min–1 compared with the significantly modified engine of the BMW R 1200 S. The maximum torque lies at 115 Nm at 6000 min–1, the highest revs of the engine reaches a peak value at 9500 min–1. Technically, the BMW HP2 Sport is based on the BMW R 1200 S.
Customised to meet the requirements of the ambitious sports rider down to the last detail, the BMW HP2 Sport is however a completely independent and absolutely exceptional motorcycle. Many detailed solutions are based on the experiences gained in long-distance races. 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 position.
