Crighton Roton Rotary Racer

In March 1991  Brian Crighton unveiled his Roton (ROtary / crighTON) race bike based on the Norton F1 engine. The Roton was designed to compete in the 500cc Grand Prix with the rules now allowing 500cc 4 strokes the rotary engine was eligible to enter when reduced down to the 500cc limit.  Steve Spray won a world championship point in the 500cc Australian Grand Prix and Grant Hodson won in the F1 race in New South Wales on the same bike.
