Engineered by Suzuki for the naked motorcycle segment, the 2003 Suzuki GX 125 utilizes a 125 cc (7.6 cu in) single cylinder, four-stroke layout. In factory specification, peak output is rated at 15.4 HP (11.2 kW), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 123.2 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
The 9.46-liter (2.5 US gal) fuel tank paired with a rated consumption of 2.61 L/100 km provides an estimated theoretical range of roughly 362 km (225 miles) between fill-ups, while factory top speed is listed at 121 km/h (75 mph).
