The bike is currently undergoing a rebuild and is set to be brought up to the new standard. The bike will be up for sale at the end of January. The BMW R100 is the first in a series of BMW motorcycles with a twin-cylinder engine. The BMW R100 is a machine which is very similar to the BMW R1200GS, but with a much larger engine. The R100 has been powered by a two-stroke engine since its introduction in 1997. The two-stroke engine has now been replaced by a four-stroke engine, which is also the same size as the two-stroke engine. The new four-stroke engine is said to produce upwards of 500 horsepower. The new engine will be fitted to the BMW R100 Cafe Racer. The bike has been fitted with an aluminium tank, a new exhaust system and an all-new suspension system.
