A couple of years after the presentation of the GSX-R750 a little brother with a 250cc engine was born. Like its big brother, the GSX-R250 had a box-frame (steel, not aluminum), full fairing, Full-floater rear swing and a four-cylinder four-stroke engine. But while the GSX-R750 engine was air and oil-cooled, the baby brother had a liquid-cooled engine. Not many examples are seen outside Japan. 17-inch cast wheels and 300 mm twin disc brake at the front.
