2009 Hyosung GT 250 Technical Analysis & Specification Breakdown

At the heart of the 2009 Hyosung GT 250 naked motorcycle, Hyosung relies on a 249 cc (15.2 cu in) oil & air-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 27.8 HP (20.3 kW) at 10,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 111.6 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.

On the scales, the GT 250 measures 155 kg (342 lbs) dry, translating to a power-to-weight ratio of 0.18 HP/kg (5.58 kg per horsepower). Rider ergonomics and chassis geometry center around a 795 mm (31.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,445 mm (56.9 in) wheelbase engineered for balanced agility and highway composure. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
