At the heart of the 2010 Kasinski Comet GTR 250 EFI sport motorcycle, Kasinski relies on a 249 cc (15.2 cu in) oil & air-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 28.8 HP (21 kW) at 10,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 115.7 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 Comet GTR 250 EFI measures 173 kg (381 lbs) dry, translating to a power-to-weight ratio of 0.17 HP/kg (6.01 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,435 mm (56.5 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.
