Believe it or not, Kawasaki has only triumphed in two 500cc class races. In 1971, Brit Dave Simmons, crossed the finish line first on a Kawasaki H1R at Jarama, and in 1975 another Brit, Mike Grant, won the Isle of Man aboard a Kawasaki when it was still a part of the Grand Prix calendar. Team Green has experienced much greater success in the smaller 125cc, 250cc and 350cc classes.
