The HP4 allows the rider to make instant gearshifts with virtually no interruption of traction force by means of the shift assistant, equipped as standard.
New seven-spoke wheels in forged light alloy and a new, lighter sprocket carrier give the HP4 a weight reduction of 5.3 lbs. compared to the S 1000 RR. The exhaust system is made entirely of titanium and saves as much as 9.9 lbs.
The HP4 is equipped with the water-cooled in-line engine of the S 1000 RR with a peak output of 193 hp at 13,000 rpm and a maximum engine speed of 14,200 rpm. As in the S 1000 RR, its maximum torque of 83 lb/ft is achieved at 9,750 rpm. BMW claims the torque has been perceptibly increased in the 6,000-to-9,750 range. In “Rain” mode there is now a smoother output and torque curve available between 2,500 rpm and 8,000 rpm.
Unlike the S 1000 RR, the 4-cylinder in-line engine in the HP4 provides the full output of 193 hp at 13,000 rpm in all modes, with an identical throttle curve.
The HP4’s instrument cluster not only has a newly designed dial face with HP4 inscription, but also provides an extended range of information and functions. The information display now shows the DDC setup menus as well as the figures for DTC adjustment and Launch Control activation.
For customers who want even more, the HP4 with Competition Package is an especially exclusive version of the motorcycle. The package includes carbon parts, wheels finished in Racing Blue Metallic, and a factory sponsor sticker kit.
