Which rider won the 1992 Senior TT riding a Norton rotary-engined motorcycle?

Steve Hislop won the 1992 Senior TT on a Norton rotary-engined motorcycle.

Hislop rode the Norton RCW588, a machine powered by a twin-rotor Wankel engine rather than the conventional piston engine used by most rivals. The victory was a remarkable engineering and sporting upset: Norton had not won the Senior TT since 1961, and the rotary project was still regarded as unconventional and difficult to develop.

The race became a classic duel with Carl Fogarty, who rode a Yamaha. Hislop started behind Fogarty on the road but overhauled him during the six-lap contest, winning by just under two minutes after setting a 121.28 mph race average. Preparations included fitting a larger screen, removing the front mudguard to improve cooling and adding fork protection. The result remains Norton’s defining modern TT success and is often confused with the marque’s earlier post-war victories.
