BMW K100 Motorcycle - Street (1983-1986)

The BMW K100, produced from 1983 to 1986, is an iconic motorcycle known as the "Flying Brick." It marked a significant shift for BMW with its water-cooled, inline four-cylinder engine. All models from this period featured a 987 cc engine producing 90 horsepower (66 kW) at 8,000 rpm and 84-86 Nm of torque between 6,000 and 8,250 rpm, utilizing a Bosch LE-Jetronic fuel injection system. Several trims were available, including the basic K100, the K100 RS (sport-touring, introduced in 1983), the K100 RT (super touring, launched in 1984), the K100 C with a small cockpit fairing, and the K100 LT (Luxury Tourer, introduced in 1986). While the core engine remained consistent in terms of displacement and power output between 1983 and 1986, BMW implemented minor adjustments and updates over the years. These revisions included changes to the starter clutch, modifications to the fuel gauge system (transitioning from a thermistor to a potentiometer in 1986), and adjustments to the footpeg mounts. There was no major generation break or significant platform change during this period. Q : How can I ensure parts compatibility for my BMW K100?
