Suzuki GS400 Motorcycle - Street (1977-1978)

The Suzuki GS400, a classic motorcycle produced from 1977 to 1978, was powered by an air-cooled, 398 cc parallel twin-cylinder DOHC engine. This model was offered in various trims, including the standard GS400 with wire wheels, the higher-end GS400E introduced in 1978 featuring cast wheels, and the more economical GS400X/XB which lacked a front disc brake and electric starter. During its short production run, the GS400 saw several notable updates. Early models experienced a horsepower increase from 34 hp to 37 hp. The 1978 model year brought the introduction of the GS400E with its distinctive cast wheels and a mildly stepped seat. The standard GS400 also received new styling with updated striping. Additionally, a minor exhaust system modification in 1978 contributed to a slight power increase, and the budget-oriented GS400X was discontinued after this year. These changes highlight a continuous refinement of the platform within its initial two years. FAQ:
