1972 Honda CB 350 Technical Analysis & Specification Breakdown

Built around Honda's classic motorcycle platform, the 1972 Honda CB 350 features a 325 cc (19.8 cu in) air-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 36 HP (26.3 kW) at 10,500 rpm while maximum torque reaches 25 Nm (18.4 lb-ft), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 110.8 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.

On the scales, the CB 350 measures 170 kg (375 lbs) wet (curb), translating to a power-to-weight ratio of 0.21 HP/kg (4.72 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 165 km/h (103 mph).
