Built around Suzuki's sport motorcycle platform, the 1988 Suzuki GSX-R 250 features a 248 cc (15.1 cu in) liquid-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 45 HP (32.8 kW) at 15,000 rpm while maximum torque reaches 24 Nm (17.7 lb-ft) at 10,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 181.5 HP per liter and a 4,500 rpm working window between peak torque (10,500 rpm) and peak power (15,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the GSX-R 250 measures 138 kg (304 lbs) dry, translating to a power-to-weight ratio of 0.33 HP/kg (3.07 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,370 mm (53.9 in) wheelbase engineered for quick, flickable steering geometry.
