1983 | GS250FW

The first 250 cm³ class model equipped with a liquid-cooled 4-cylinder DOHC engine in the world


The GS250FW was the world’s first model to adopt a 4-stroke liquid-cooled 4-cylinder DOHC engine in the 250 cm³ market where 2-cylinder engine models had dominated. Generating maximum horsepower of 36 PS, this engine delivers smooth acceleration, quietness, and powerful riding performance. Substantial weight reduction was realized together with the engine itself by adopting forged aluminum parts such as separate clip-on handlebars, footpegs, and a muffler bracket, in addition to to the square-piped frame and swingarm. The front end pairs the Anti Nose Dive Fork (ANDF) system with a 16-inch wheel. The rear end features upgraded parts such as the Full-Floater Suspension and the Remote Controlled Pre Load (PCPL) mechanism. Variations include half-faired and mini-faired models.
