BMW Mottorad is introducing its latest high-performance roadster, which is derived from the BMW S 1000 RR -- the BMW S 1000 R. The new naked superbike is directly based from the S 1000 RR and even uses the same innovative technology, as evidenced by the resemblance to the "RR" family. This new naked bike features looks that radiates aggressive, dynamic energy while exuding emotive roadster styling.
The BMW S 1000 R is powered by a 999cc four-cylinder in-line engine derived from S 1000 RR that was developed to be able to provide a punchy response all though the rpm range. To make the S 1000 R perfect for both for daily use and for sporty riding on the open road, engineers increased dramatically the low and mid-range power and torque and reduced the maximum rpm by around 2,000 rpm.
This resulted to 118 kW (160 hp) of maximum output reached at 11,000 rpm and 112 Nm (83 lb-ft) of peak torque reached at 9,250 rpm.
Up to 7500 rpm, the modified 999cc four-cylinder in-line engine develops 10 Nm (7 lb-ft) more torque than the S 1000 RR's, paving way for a punchy low-end response. The resulting increase in power and torque was also achieved by employing redesigned cylinder head ducts, modified cam profiles and through ppropriately modified engine management.
The new BMS-X engine management system also supports an E-Gas “throttle-by-wire” system. The BMW S 1000 R now comes with two riding modes -- “Rain” and “Road” -- and Automatic Stability Control (ASC) as standard.
The two modes adjust to different road surface conditions by employing different power and torque curves while applying different levels of Race ABS and ASC intervention. Available as an ex-works option is the Dynamic Traction Control (DTC) which features two more riding modes – “Dynamic” and “Dynamic Pro. DTC allows riders to optimize the S 1000 R’s sporty performance potential both on the road and on the race track. [source: BMW]
