BMW HP4 supersports bike based on S1000RR

BMW has unveiled the latest bike to join its High Performance (HP) range – the BMW HP4. Like its other HP siblings (HP2 Enduro, HP2 Megamoto and HP2 Sport), its based on an existing Motorrad model, which in this case is the BMW S1000RR. It is the first four cylinder bike in the BMW HP family. The BMW HP4 provides the homologation basis for the use of BMW motorcycles in motorcycle racing categories such as superbike and superstock categories. It has a standard passenger seat cover for a monoposto look. There’s also a passenger seat package as an ex works option, which includes the passenger seat as well as the passenger footrests. Fitted as standard is a Dynamic Damping Control DDC system, which allows dynamic damping adaptation of the pside-down fork and spring strut to the specific situation on the road. The damping is adapted to the current manoeuvre or road surface by means of sensor-supplied parameters via electrically controlled regulation valves. In this way, the HP4 offers optimum damping in every situation, handling long and short shocks virtually perfectly so as to provide maximum traction and safety.

The new HP4 is fitted with the water-cooled 4-cylinder in-line engine with a peak output of 193 hp at 13,000 rpm and a max engine speed of 14,200 rpm. Its maximum torque of 112 Nm is reachedat 9,750 rpm. The torque has been perceptibly increased in the 6,000-9,750 rpm range. In “Rain” mode there is now a smoother output and torque curve available between 2,500 rpm and 8,000 rpm. This is plenty of power considering the HP4 weighs just 199kg including a 90% full tank of petrol. The rear tyre of the HP4 uses a 200/55ZR17 size. As for the brakes – the HP4 has Brembo monoblock calipers and 9x floating brake discs at the front as well as an upgraded Race ABS system. There are four different ABS modes to be picked from – rain, roads, racetrack and slick. Unlike the RR where horsepower is tuned down to 163hp in rain mode, the engine’s maximum 193hp is available in all four ABS modes. BMW has equipped the HP4 with a shift assistant, where you can do clutchless upshifts if you want. Downshifts still require you to use the clutch, and if you touch the clutch it disengages the shift assistant.
