Frame no. 16R31443
Engine no. IAI-29758
Established in 1931 as a tire manufacturer, Bridgestone also built motorcycles between 1952 and the early 1970s, establishing an unrivalled reputation for design innovation and engineering excellence. The firm started by using proprietary engines provided by the Fuji Precision Industry Company (later reconstituted as Prince Motors) before acquiring its engine supplier in 1960. By the decade's end, the Ageo City plant was capable of turning out 250,000 motorcycles and 350,000 bicycles annually. Bridgestone commenced with a range of mopeds before moving up market with a range of disc valve induction two-strokes that was topped by the legendary 350 GTR. The Japanese company's flagship model was the GTR, a 345cc two-stroke twin with disc valve induction and a six-speed gearbox. This state-of-the-art motor produced 40bhp at 7,500rpm, an output good enough for a top speed of around 112mph and a standing quarter-mile time of 13 seconds. The smallest twin-cylinder model displaced 175cc and was available in two versions: the Dual Twin Roadster and Hurricane Scrambler, the latter featuring upswept exhausts. A maximum power output of 20bhp was claimed for the 175S, good enough for a top speed of more than 80mph. A model rarely seen in the US, this Bridgestone Dual Twin has been part of a private European collection for years.
Presented in largely original condition, this machine shows some evidence of repainting. The Bridgestone will undoubtedly require some recommissiong before use.
