BMW K100LT Motorcycle - Street (1987-1992)

The BMW K100LT, produced from 1987 to 1992, was a luxury touring motorcycle renowned for its inline-four "Flying Brick" engine. This liquid-cooled, four-stroke, horizontal in-line four-cylinder engine had a displacement of 987 cc. It produced 90 horsepower (66 kW) at 8,000 rpm and a maximum torque of 86 Nm at 6,000 rpm, featuring a DOHC (Double Overhead Camshaft) design with two valves per cylinder. The K100LT was a specific luxury touring trim within the broader K100 family. Introduced in 1986, it largely superseded the K100 RT by 1987, offering a full fairing, a taller windscreen, and more luxurious standard equipment, including a top case, radio preparation, and a more comfortable seat. There were no significant mid-cycle generation or engine changes for the K100LT between 1987 and 1992; the 987cc, two-valve engine remained consistent. Minor updates were made to the broader K100 series (such as pinned piston rings in 1989), but these did not alter the fundamental platform of the K100LT. The successor, the K1100LT, with a 1092cc, four-valve engine, only appeared as a 1993 model. FAQ:
