The R850 R Classic is a more classicly styled BMW. In part it is similar
to the 2002 model year R850 R, from where it derives its oil cooler, oil
cooler pipes, tank and seat.
The engine and gearbox come from the standard R850 R that was for sale in
the UK during 2003 and the front and rear spring struts come from the R1150
R Rockster. The high-rise handlebar is the same as on the special version
produced for the police.
The 848cc air and oil-cooled flat-twin, four-stroke engine is rated at
53kW (70bhp) at 7000 rpm with maximum torque of 78Nm at 5600 rpm. Power is
transmitted by a six-speed gearbox. Up front is the EVO braking system with
320mm dual discs and four-piston caliper.
Ride an R850 R and you will soon appreciate the generous steering lock,
low centre of gravity (thanks to that flat-twin engine), soft-tune motor and
responsive throttle that makes the R850 R such an easy machine to ride.
Excellent manoeuvrability and agility belie the machine?s capacity rating.
On the open road the R850 R Classic is a fatigue-free and comfortable
bike to ride. Aerodynamic qualities, combined with BMW's unique Telelever
front suspension, ensure that the R850 R is one of the most stable naked
machines available. At cruising speeds, rider input is minimal.
As you would expect from BMW, a full range of special equipment,
dedicated luggage and accessories, as well as ABS and heated grips is
available. The R850 R Classic is available only in Night Black with a black
seat.
