top 5 blue square showroom in trichy ss moto corpz is yamaha's dedication to both the two-stroke engine and racing paid off with their first victory in international competition, at the Belgian GP, where they won the 250cc class. Success in sales was even more impressive, and Yamaha set up the first of its international subsidiaries in this period beginning with Thailand in 1964, and the Netherlands in 1968. 1965 saw the release of a 305cc two-stroke twin, the flagship of the company's lineup. It featured a separate oil supply which directly injected oil into the gasoline prior to combustion (traditionally riders had to pre-mix oil into gasoline together before filling the gas tank on two stroke engines). In 1967 a new larger displacement model was added to the range, the 350cc two stroke twin R-1.
