A couple of years after the presentation of the Suzuki 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. Despite having a steel frame, it still managed to be a 138 kg (304 lbs) lightweight dry. The acclaimed curb weight was 158 kg (348 lbs). A half-fairing version was also available.

While the GSX-R750 engine was air and oil-cooled, the baby brother had a liquid-cooled short-stroke engine with a cylinder bore of 49 mm and a piston of 33 mm, delivering 45 bhp at 14,500 revs. It had 17-inch cast wheels and 300 mm twin disc brake at the front. The 3-spoke wheels had a wing cross-sectional shape, intended to reduce rotational resistance and noise.

The riding position was not as forward-leaning as one could assume from a extreme sports bike. The handlebar was moved to a lower position on the 1989 K model.

The GSX-R250 was launched in March 1987. Two months later, in May 1987, an All-Black version with Bronze colored livery was released. Not many examples of any of the model versions are seen outside Japan.

Colors available for the 1987 GSX-R250 were Blue/White, Pearl Twinkle Red / Prussian Blue Metallic (9RD) and Pearl Novelty Black (33J).

The front turn signals were smoke colored ands built now built in the cowl, similar to the GSX-R750 of the same period. The rear mirrors were also re-designed.

The 1989 GSX-R250R (GJ73A) had a new welded aluminium twin tube frame, a swing arm with a stabilzer, 18-inch rear wheel and larger front brakes. The model also had a redesigned, slightly slimmer seat, resulting 4 mm lower seat height. The handlebar was replaced to a lower position, giving a sportier riding position. The silencer that was coated black earlier was now aluminium colored.

A letter 'R' was added to the model name, stating that this was more radical version compared to the somewhat ”more polite” GSX-R250, that was still available in 1989 – Prussian Blue Metallic (24V) with Gray Metallic (17U) livery and White wheels, Pearl Novelty Black (33J) with Gray Metallic wheels (both had Gray Metallic and White diagonal stripes) and 'Black Version' with Black wheels.

Two GSX-R250R was offered in Marble Italian Red / Space Black (8RY) and Pearl Novelty Black (33J). Both had White Suzuki logos, the Black version had Gray Metallic colored wheels, the Red/Black had Red wheels.

A SP model (Sports Production, pure street-legal racing model), with a single seat, a close ratio transmission and fully adjustable suspension was launched together with the 1989 GSX-R250RK in February 1989. The engine was equipped with a slingshot carburator and SCAI, Suzuki Condenced Air Intake.

The SP model's front suspension preload and compression can be adjusted in 10 steps and the rear suspension preload can be adjusted in 4 steps and the compression in 21 steps. The rear shock had a separated gas chamber and could be adjusted remotely.

The SP model was available in Blue and White, Suzuki's Racing colors.
