2013 BMW S1000RR HP4.

                                   2013 BMW S1000RR HP4.

The BMW S1000RR is a sport bike initially made by BMW Motorrad to compete in the 2009 Superbike World Championship, that is now in commercial production. It was introduced in Munich in April 2008.
The 2013 HP4 engine specs are the same as the standard S1000RR, but BMW have given the HP4 more mid-range power and a smoother throttle response. With a claimed 193 horsepower at 13,000 revolutions per minute (rpm) and 83 ft-lbs. of torque at 9750 rpm, the HP4 provides more than enough power for the street, and certainly enough for serious track day riders, as well.
The new HP4 is BMW Motorrad’s first 4-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 4-cylinder engine in the segment provides uncompromising power with an output of 193 bhp and a maximum torque of 83 lb/ft. 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 2013 BMW HP4’s Anti-lock Braking System (ABS) and wheelie control almost seem like afterthoughts in the face of such engineering as DDC and DTC, but they add to the overall ride and help complete the electronics package. BMW has left no area of motorcycle dynamics unstudied and has delivered a solution for them all.
Using throttle position, wheel speeds and suspension movement, DDC adjusts every 10 milliseconds to rider input and road conditions, increasing damping during acceleration, heavy braking and directional changes, and softening the blow in other critical areas, such as full lean, to increase edge grip.
With forged alloy wheels, an Akrapovic titanium exhaust, a lighter sprocket carrier and battery, and many, many carbon-fiber parts, the 439-pound HP4 is 15 pounds lighter than the standard S1000RR. Weight and parts aside, BMW’s selection of technological advances on the 2013 HP4 are the real story. The 2013 HP4 has traction control, wheelie control, launch control, anti-lock brakes and the first dynamically adaptive, auto-adjusting electronic suspension ever available on a production motorcycle: Dynamic Damping Control (DDC).
