The Fritz designed engine and chassis finally came together as a perfect marriage in the form of the 1923 BMW R 32 motorcycle and was an immediate success. With one 22mm BMW Special carburettor feeding two cylinders of just 5.0:1 compression ratio via one inlet side-valve per cylinder (the one exhaust valve was also side-valve), the R 32 was good for 90-100km/h (56-62mph) and 80mpg (3.5litres/100km).
