2010 BMW GS and RT

By Kevin Ash - 30/03/2010

BMW‘s top-selling R1200 GS and R1200 GS Adventure are getting double overhead cam engines derived from the HP2 Sport for 2010. The new engine is being phased in across BMW‘s air-cooled twin range, replacing the current high cam motor which made its debut in 1993 in the R1100 RS.

As a consequence, the power output increased by 5 per cent to 109bhp (110PS, 81kW) at 7,750rpm, while torque is up to 88lb.ft (120Nm) at 6,000rpm. The HP2 Sport engine is also significantly smoother and more willing to rev than the high cam twins - peak rpm on the 2010 GS is up 500rpm to 8,500rpm.

Other changes include an electronically-controlled flap in the exhaust system to allow louder sound while controlling volume during noise emission tests.

Colours available are white, red, grey and black for the GS, and grey or yellow for the GS Adventure.

The R1200 RT tourer also benefits from the DOHC power unit in 2010, as well as a wider range of other changes than the GS. Power and torque figures are the same as the GS and the exhaust flap sound control is also fitted. In addition, the RT gets the sophisticated ESA II electronic suspension control first seen on the K1300 series in 2009, which adjusts spring rate as well as preload and damping according to load and riding style.

The fairing has been redesigned to improve wind and weather protection, while the cockpit is also new, including switchgear and hydraulic reservoirs. The sound system now includes the facility to play from an iPod or USB/MP3.

The colours available are metallic white, light grey, dark grey or a multi-colour option with dark grey base.

Prices and availability will be announced later this month.
