This one of the two 1989 Fior 500s made, and as 1989 was the final year they competed in the 500cc World Championship, it represents the peak of Frenchman Claude Fior’s GP designs.

His original front end design first saw the light of day in 1980 as part of an aftermarket chassis for TZ250/350s. In 1986 and 1987 his bikes, powered by Honda RS500 motors, were entered in the 500cc championship but only scored a single point for both years.
