BMW R 850 R

The BMW R 850 R is a roadster motorcycle from the Bavarian maker BMW, part of its R range of boxer-engined machines. Its 848 cubic centimetre displacement is obtained by reducing the bore from the 99 mm used on the R 1100 R to 87.5 mm. The German article on the R 1150 R describes it as an otherwise identical but lower-powered variant of that model, rated at 71 PS (52 kW) with a maximum torque of 77 Nm, and notes that it was often used as a police motorcycle.
