Pure Performance. When light weight, massive power and razor-sharp handling are combined, the result is known as HP - High Performance. The new HP4 is BMW Motorrad's first four-cylinder model to wear the HP badge. Based on the S 1000 RR, a purebred factory motorcycle has been developed - made from the very best materials and molded into unparalleled design. The lightest four-cylinder engine in the segment provides uncompromising power with an output of 193 bhp and a maximum torque of 83 foot pounds. The new exhaust silencer provides a higher level of torque in the mid-range, so there is power available where it's needed most to deliver stunning lap times. The new HP4 comes into its own with its refined paint finish in White and Racing Blue. The HP4 will only be available in limited numbers through 2014.
