Vehicle Information
Suzuki GN400 Motorcycle - Street (1980-1982)
The Suzuki GN400, produced from 1980 to 1982, is a classic street-oriented motorcycle. Derived from the SP400 Enduro platform, it features a robust air-cooled, 396 cc SOHC single-cylinder, two-valve engine. This engine delivers 27 horsepower (20 kW) and 29.4 Nm of torque, paired with a 5-speed manual gearbox. Notably, all GN400 models from this period relied solely on kick-start, without an electric starter. Across its production run from 1980 to 1982, the Suzuki GN400 maintained a consistent engine and core platform. There were no significant mid-cycle generation or engine changes. Variations primarily involved trim levels and cosmetic updates. Trims like the standard GN400/GN400E, the GN400L (with higher handlebars, a step seat, and alloy wheels), the GN400TD (featuring a "soft chopper look" and wire-spoke wheels), and the GN400X (with spoke wheels, a flatter seat, and shorter handlebars) offered different styles. A minor update in 1981 included new graphics on the tank and side cover. Q: How do I ensure I'm selecting the correct parts for my Suzuki GN400?
