350 GTO

1967 Bridgestone 350 GTO Technical Analysis & Specification Breakdown

Built around Bridgestone's allround motorcycle platform, the 1967 Bridgestone 350 GTO relies on a 350 cc (21.4 cu in) air-cooled twin, two-stroke powerplant. In factory specification, peak output is rated at 40 HP (29.2 kW) at 7,500 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 114.3 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

Rider ergonomics and chassis geometry center around a 178 mm (7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,372 mm (54 in) wheelbase engineered for quick, flickable steering geometry. The 14.38-liter (3.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
