The Bridgestone 175 Dual Twin was a parallel-twin two-stroke motorcycle of about 175 cc, in effect a doubled-up 90 cc Bridgestone Sport. Rotary valves controlled the inlet and the carburettors sat near the ends of the crankshaft, and it was the first Bridgestone to use oil injection, with the oil carried in a separate tank rather than mixed with the petrol. Its name came from its unusual gearbox, a four speed rotary-shift unit that a second lever, the Sport-Shift, converted to a conventional five speed pattern. A street scrambler version with high level exhausts was called the 175 Hurricane, and a limited 175+ Racer was built in 1967. Sources give the introduction as 1965 or 1966 and the capacity as 175 cc or 177 cc.
