(1984 / Production Model)
This was a street-legal trail model that retained the mechanisms, performance and image of Yamaha's competition motocrossers. Its liquid-cooled 2-stroke single-cylinder engine was outfitted with exclusive Yamaha 2-stroke technologies like YEIS to smooth out the intake pulse and YPVS with its variable valve to increase exhaust efficiency. The result was a high power output of 30 PS. The front wheel was fitted with a disc brake designed specifically for trail models, an advanced feature at the time.
