RD400 / RD350 / RD250 / R5 Parts

The two-stroke bullies. In 1972 Yamaha released the 350cc R5. In the same year, Yamaha 250 and 350 twins left the four-stokes behind. A four-stroke motor would not win Daytona until 1985. The fact is Yamaha for the record won thirteen consecutive times. These small two-strokes could not be beat. These were production out of the box stock, powerful, high rpm motors that would take the harsh punishment that was built into a small, lightweight package. The earlier models were piston port induction up to the year 1973.

Yamaha then introduced the Reed Valve induction system creating even more controllable power. This design was certainly a people pleaser. RD’s became a top selling bike in the U.S. They were also known to become an excellent production-class road racer. The perfect choice for the privateer racer. The RD’s also had taken their place as the local street racer or custom Café bike to own.

In 1976 the RD350 was replaced by the increased piston displacement and stroke length of the RD400. This motorcycle also had it reigns on and off the track. Yamaha keeping its two-stroke “king of the hill” claim to fame until 1979 when the factory production street two-stroke journey came to its end.
