The Bridgestone 90 Sport, also called the BS-90, was a 90 cc single-cylinder two-stroke motorcycle and the first of the new range that Bridgestone built after hiring engineers from Tohatsu and Lilac in the early 1960s. Its engine used rotary disc-valve induction and produced 7.8 bhp, and it had a pressed steel frame with telescopic front forks. A version with a high level exhaust was sold as the Mountaineer, and race-prepared SR versions were built for American dirt and road events. The 90 became the basis of the later 100 Sport and, as a doubled-up engine, of the 175 Dual Twin. Sources differ on its date, with the Bridgestone Registry history giving 1964 and the Wikipedia article 1965.
