GSX-R125

2023 Suzuki GSX-R125 Technical Analysis & Specification Breakdown

Built around Suzuki's sport motorcycle platform, the 2023 Suzuki GSX-R125 relies on a 124 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 14.8 HP (10.8 kW) at 10,500 rpm while maximum torque reaches 11 Nm (8.1 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 119.4 HP per liter and a 2,500 rpm working window between peak torque (8,000 rpm) and peak power (10,500 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the GSX-R125 measures 137 kg (302 lbs) wet (curb), translating to a power-to-weight ratio of 0.11 HP/kg (9.26 kg per horsepower). Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank paired with a rated consumption of 1.92 L/100 km provides an estimated theoretical range of roughly 573 km (356 miles) between fill-ups, while factory top speed is listed at 116 km/h (72 mph).
