Positioned in Kasinski's sport motorcycle lineup, the 2010 Kasinski Comet GTR 650 EFI relies on a 647 cc (39.5 cu in) liquid-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 89.6 HP (65.4 kW) at 9,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 138.5 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 650 EFI measures 198 kg (437 lbs) dry, translating to a power-to-weight ratio of 0.45 HP/kg (2.21 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 17.03-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
