1973 Suzuki GT 185 Technical Analysis & Specification Breakdown

Engineered by Suzuki for the classic motorcycle segment, the 1973 Suzuki GT 185 pairs a 185 cc (11.3 cu in) air-cooled twin, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 21 HP (15.3 kW) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 113.5 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 1,290 mm (50.8 in) wheelbase engineered for quick, flickable steering geometry. The 7.57-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 145 km/h (90 mph).
