Hossack were motorcycles produced by Norman Hossack from 1984 to 1988.
Norman Hossack was involved with chassis and then went on to design a new form of frame. This had an innovative front fork that resembled a girder fork, but was actually a twin-wishbone system, similar to that of a car's front suspension.
The design worked well and several machines were built, fitted with a variety of engines. Firstly they were Honda, Rotax and Yamaha, then later came a front-fork conversion for a K100RSBMW.
