125ccRA97(1964-66)

Leap forward with Yamaha's first liquid-cooled engine

Yamaha's GP125 machines had progressed from the 1961 model RA41 through the RA55 and RA75 with 2-stroke, single-cylinder engines. This format failed to remain competitive, however, as the other makers went to multi-cylinder engines. This led to the development of the RA97 with an air-cooled 2-cylinder engine based on the 250cc RD56. In its debut race at the 1964 Dutch GP, P. Read rode it to an impressive 2nd-place finish. In the latter half of the 1965 season, the RA97 evolved into Yamaha's first machine with a liquid-cooled engine and it won the Isle of Man TT ridden by Read. In 1966 the power was raised to 32PS and it waged a fierce battle for the title with five wins.
