As an automobile manufacturer, BMW had about twenty years of experience with liquid-cooled overhead camshaft inline engines. This was carried over to the K100 engine, which used a Bosch LE-Jetronic fuel injection similar to that being introduced on their second generation 3 Series cars. Replacing the Bing carburettors traditionally used on BMW motorcycles, the fuel injection system increased power, broadened and smoothed the powerband, and reduced fuel consumption, partly by shutting off fuel under deceleration to 2000 rpm. The engine also featured a breaker-less electronic ignition system.
