1991 BMW 998cc K100RS
Registration no. J56 GCW
Frame no. 0203821 K100RS
Engine no. 104EB 2990 2100

An all-new design that was supposed to replace BMW's traditional flat-twins, the K100 arrived for 1984 restating the virtues of solidity, comfort and exemplary build quality long associated with the marque. An 8-valve twin-cam unit displacing 998cc, the brick-like, four-cylinder motor was laid on its side, lowering the centre of gravity, and mounted fore-and-aft to facilitate the retention of BMW's characteristic shaft drive. Bosch electronic fuel injection was employed and the long-stroke four developed its maximum output of 90bhp at a relatively low 8,000rpm. The K100 spawned a 750cc three-cylinder variant (the K75) and was later enlarged to 1,200cc, gaining a 16-valve cylinder head along the way. Model designations were carried over from the large-capacity twins: the K100RS being the top-of-the line sportster and the K100RT the tourer.

No significant history known about this 16-valve K100RS, which currently displays a total of 158,222 miles on the odometer and has been stored for some time. There is some minor bodywork damage and the left-side front indicator/mirror is missing whilst the machine's mechanical condition is not known. The machine is offered with a V5C document, a quantity of invoices, expired MoT's (most recent in 2018), Riders handbook, panniers (no keys) and is sold strictly as viewed.
