The new S 1000 R naked bike from BMW Motorrad is directly derived from the S 1000 RR superbike and uses pretty much the same technology. In terms of styling, with its “tail up – nose down” stance, the close family resemblance to the “RR” is instantly obvious.
By modifying the S 1000 RR’s 999 cc four-cylinder in-line engine for use in the S 1000 R, the engineers have been able to significantly increase the low and mid-range power and torque. At the same time, maximum rpm has been reduced by approximately 2,000 rpm. Maximum power of 160hp (118 kW) is reached at 11,000 rpm and peak torque of 112 Nm (approx. 83 lb-ft) at 9,250 rpm. Up to 7500 rpm, this engine version develops 10 Newton metres (approx. 7 lb-ft) more torque than the S 1000 RR. Among other things, this was achieved by using redesigned cylinder head ducts, modified cam profiles and appropriately modified engine management. The new BMS-X engine management system also supports an E-Gas “throttle-by-wire” system.
The S 1000 R comes with two riding modes and ASC (Automatic Stability Control) as standard. The “Rain” and “Road” modes cater to different road surface conditions using different power and torque curves, and applying different levels of Race ABS and ASC intervention.
Dynamic Traction Control (DTC), incorporating a further two riding modes – “Dynamic” and “Dynamic Pro” – is available as an ex-works option. DTC, which includes a banking angle sensor, offers safe and dynamic acceleration, claims BMW Motorrad.
The chassis and suspension of the S 1000 R is designed to cope with the power delivery of the four-in-line engine. Based on that of the S 1000 RR, it an aluminium alloy perimeter frame, in which the engine forms part of the load-bearing structure. As on the RR, an adjustable upside-down fork and a dual swingarm with adjustable central spring strut guide the wheels front and rear. Roadster-specific suspension requirements are met by a slight change in geometry. As on the RR, braking is provided by a braking system that comprises a twin-disc brake with two radial 4-piston fixed callipers at the front and a single-disc brake at the rear, with partially integral Race ABS. Dynamic Damping Control (DDC), available as an ex-works optional extra, adds electronic damping control functionality.
Race-inspired features also extend to the cockpit of the S 1000 R. With an LC display with analogue rev counter, the instrumentation is capable of showing a variety of data, from the gear display and riding mode display to a lap timer. For better gear changes, an individually programmable quick-shifter is fitted.
