Ahead of EICMA, BMW has released information on the 2011 BMW R1200R & 2011 BMW R1200R Classic street bikes (along with the 2011 BMW G650GS). Getting the R1200GS/R1200GT’s dual-overhead cam twin-cylinder boxer motor, the R1200R series gets a 500 RPM boost, more power (110hp), and more torque (87.77 lbs•ft) from the updated air-cooled 1170cc motor. Other minor updates include a more distinct old school style for the 2011 BMW R1200R Classic, while both bikes benefit from an increased stand pipe (41mm up from 35mm) on the front Telelever suspension.
The rumors appear to be true, and the BMW R series is getting an update to its motor for 2010. Maintaining its existing 1,170cc displacement, the most notable change to BMW’s flat boxer motor is a dual-overhead camshaft (DOHC) cylinder head setup, which was previously only seen on the HP2 Sport.
With the bore and stroke staying the same for 2010, the R lineup will continue to use the same 101 x 73mm cylinders, making a total of 1,170cc’s. The real changes and improvements come from the new cylinder head design. The DOHC design features two chain-driven camshafts, with each camshaft controlling both an intake and exhaust valve in the radial four-valve head.
