Positioned in ATK's naked motorcycle lineup, the 2016 ATK GT250 features a 249 cc (15.2 cu in) oil & air-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 25 HP (18.2 kW) at 10,000 rpm while maximum torque reaches 22 Nm (16.3 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 100.4 HP per liter and a 2,500 rpm working window between peak torque (7,500 rpm) and peak power (10,000 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 GT250 measures 166.9 kg (368 lbs) dry, translating to a power-to-weight ratio of 0.15 HP/kg (6.68 kg per horsepower). Rider ergonomics and chassis geometry center around a 762 mm (30 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,509 mm (59.4 in) wheelbase engineered for balanced agility and highway composure. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
