Engineered by Suzuki for the sport motorcycle segment, the 1987 Suzuki RG 400 Gamma utilizes a 400 cc (24.4 cu in) liquid-cooled v4, two-stroke layout. In factory specification, peak output is rated at 59 HP (43.1 kW) at 9,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 147.5 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
The 22-liter (5.8 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 230 km/h (143 mph).
