In 1987, the German motorcycle manufacturer released the BMW K 100, a liter-class naked machine that debuted in 1983 and continued production until 1992. It was in the fifth consecutive production year and had the same technical, visual, and performance specifications without any changes.

In the visual department, the motorcycle had standard fittings, such as a round headlight integrated into a small cowl, a one-piece dual seat, a four-into-one exhaust system with a muffler mounted on the left-hand side, and aluminum wheels.

Power-wise, the 1987 BMW K 100 had installed a 987cc four-stroke liquid-cooled four-cylinder engine underneath the fuel tank, delivering an output power of 90 hp at 8,000 rpm and 84 Nm (62 lb-ft) torque at 8,250 rpm.

The bike was available in several versions, like the K100 C with a small cockpit fairing mounted on the handlebar, the K100 RS with a lower fairing and a sports fixed fairing, the K100 RT with a full touring fairing, the K100 LT with a taller windscreen and luxury touring equipment, and K100 TIC developed for Police, Ambulance, Fire, and Military departments.

A telescopic fork and two 285 mm brake discs with dual-piston caliper handled the bike's front end, while the rear end was controlled by a Monolever system and a single 285 mm disc with a single-piston caliper.
