Collection items
(1981 / Racing Machine)
This was a 250cc class motocross factory machine. First introduced with a liquid-cooled engine, it was re-designed with an air-cooled engine just before the series began. It featured Yamaha's exclusive YPVS, a variable exhaust valve to prevent exhaust gas blow-by, and also newly adopted the YEIS intake system that achieved smoother flow of the air-fuel mixture. The result was improved output across the entire rpm range. It also adopted a linked-type Monocross suspension with a bell crank. Neil Hudson rode this machine to the World Championship title.
