The BMW K100 was a family of standard or sports touring motorcycles manufactured by BMW from 1982 until 1992. The bike was powered by an in-line four-cylinder engine and was known as the "Flying Brick."
The motorcycle was available in several versions, like the basic K100 model without a fairing, 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, K100 LT with a taller windscreen and luxury touring equipment, and K100 TIC developed for Police, Ambulance, Fire, and Military departments.
In 1984, the German motorcycle maker introduced the BMW K100, a naked sports touring motorcycle that debuted in 1983. It suited those riders who desired a litter-class motorcycle that blended performance and agility in a single package.
Visually, the bike had standard fittings, such as a small front cowl with a single headlight unit, a one-piece double seat with pillion grab rails, a four-into-one exhaust system with a single muffler mounted on the left side, and eight-spoke alloy wheels.
The 1984 BMW K100 had installed a 987cc four-stroke liquid-cooled four-cylinder engine underneath its fuel tank. The engine was fed by a fuel injection system, delivering an output power of 90 hp with a peak force at 8,000 rpm and 84 Nm (62 lb-ft) torque at 8,250 rpm.
