(1965 / Racing Machine)


This machine evolved from the RD48 (1961), Yamaha's first 250cc GP bike. It mounted a powered-up 2-cylinder rotary disc valve type 2-stroke engine with a separate float chamber type carburetor and forced lubrication on a chrome-molybdenum pipe featherbed type double cradle frame. Its debut race was in the 1st All Japan Road Race Championship in 1962. The following year it began competing overseas and through yearly spec changes like the adoption of a 7-speed transmission, it won 15 GP races ('63–'65). In 1964 and 1965, Phil Read rode it to help bring Yamaha both the Rider and Constructor titles.
