THIS is the BMW HP2 Sport, the first production motorcycle with a double-overhead cam Boxer engine, a clutchless quickshifter six-speed transmission (like Tiptronic for bikes) and lightweight carbon fairing. The new HP2 Sport has the most powerful BMW Boxer engine ever. It packs over 128hp at 8,750rpm and 115Nm of torque at 6,000rpm - powering a dry weight of just 178kg.
