BMW R45

The BMW R45 was a horizontally opposed twin that BMW introduced in the late 1970s to extend its boxer range, looking like a scaled-down version of the larger models with sharper, more modern styling and reduced weight and dimensions. It used the Type 247 engine with smaller pistons, carburettors and a different final drive, displacing 473 cc and producing 35 hp (26 kW) at 7,250 rpm, or 27 hp for the German market to qualify for cheaper insurance. Aimed mainly at learner riders, some 28,000 were produced before production ceased in 1985. Bike magazine measured a top speed of 95 mph (153 km/h) in 1979, and today the R45 is popular with custom builders who convert it into café racers and street scramblers because of its compact dimensions.
