The New BMW HP4 carries a lot of evolution in the technology and sophistication of these features using the 4-Cylinder in line engine.
This engine is claimed to produce a maximum power up to 190 hp at 13,000 rpm of rotation and torque was 83 ft-lb. Torque is starting to feel from 6,000 to 9,750 rpm. Just like its predecessor, this bike also comes with a choice of four riding modes, namely Rain, Sport, Race and Slick.
Adjustment done by BMW. For example in rain mode, power is not immediately drop. Maximum power can still be felt, but the torque at 2,500 to 8,000 rpm with fine set which the rider stay safe while the motor was running on high speed.

In slick mode or racing mode, also installed the latest launch control. Just like motorcycle racing in WSBK or MotoGP class, launch control feature helps maximize acceleration during start. Peak torque will be concentrated on the rear wheel, rider stay focused to control the acceleration at start with open regardless of the clutch lever throttle is too big or small. Launch control is also integrated with the anti-wheelie, the machine will automatically reduce torque bursts detected when the front wheel lifted too high.

For the shock absorber are integrated with the engine control unit and the sensor box, which means it is connected also with the Antilock Brake System (ABS) and traction control. Data received from the sensor box sent directly to the shock absorber and then work harden or soften damping force by adjusting valves or valve damping.

During acceleration, for example, the weight of the vehicle would certainly bigger behind. Then automatically valve rear shock absorber suspension will make the character so much harder to be more stable and provide better traction. So also when crossing the bend sequence and braking, suspension will always provide comfort and stability for the rider.
The BMW HP4 is also equipped with anti-lock brakes system (ABS) with the same
racing version of the BMW S1000RR. ABS data used in slick driving mode,
obtained directly from Germany's IDM Championship arena. Being the
brakes, continue to use the type monobloc Brembo calipers.
All these features are enhanced by the overall weight of the BMW HP4 is lighter than the BMW S1000RR, weight reduction is obtained thanks to the application and forget type rims titanium exhaust much lighter than the standard version. The design is almost no difference with the BMW S1000R, fairing and other designs are similar
Special HP4 Carbon comes with gas tank wrapped in carbon materials. Rims match the body color, the metallic blue and footrest color variety. *** [MOTORCYCLE DAILY | FROM VARIOUS SOURCES | OVI | PIKIRAN RAKYAT 19102012]
