BMW has updated the cylinder head and intake system, ultimately growing peak power figures by 6 horsepower and increasing torque figures near 5000 rpm. Specific changes include reshaped intake and exhaust ports, a new cam shape for the intake camshaft, plus lighter intake valves and intake valve springs. The velocity stacks were shortened (the variable length system remains), which in combination with the aforementioned changes, improves the engine’s ability to get the exhaust gases out of the cylinder and the fresh air/fuel mix in. Moreover, the servo motor acting on BMW’s ride-by-wire throttle valves was made smaller, which enabled engineers to grow the airbox and go to a fully symmetric design for optimized power output.
Spent gases exit a newly shaped exhaust with twin-pipe design and no under-engine canister, updates which combine to lower back-pressure and increase torque at medium revs. The exhaust looks better in person than it does in pictures, and contributes to a massive 6.6 pound decrease in overall weight. Like any other BMW S 1000 RR exhaust, the system has a bark that dwarfs the exhaust note of any other OE exhaust system. And need we mention again its 6.6 pounds lighter
Standard riding modes include Rain, Sport, and Race, but you can upgrade to the Pro riding mode, which features two additional riding modes, Slick and User, along with Dynamic Traction Control (DTC), which is adjustable between -7 to 0 to +7 settings when riding in Slick or User. In addition to this, the Pro riding mode includes launch control as well as a programmable pit lane limiter, electronic functions that are very easily controlled by the starter button. In User mode, riders can select a setting for the Race ABS, Dynamic Traction Control (DTC), and Dynamic Damping Control (DDC) suspension. In the other modes, these settings are determined for you..
