The Yamaha 0WH0 for 1997 had a new engine with an enlarged engineangle of 75 degrees. This was also done to create more space for the large air-box needed. The shape of the exhaust ports was changed into a kind of “T” shape. The motor had new crankshafts and the drive axle of the gearbox was mounted higher in the crankcases. Luca Cadalora won 2 GP’s with it and finished 6^th in the World Championship, Norick Abe became 7^th.
