Engineered by Cagiva for the naked motorcycle segment, the 2008 Cagiva Raptor 650 features a 645 cc (39.4 cu in) liquid-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 73.8 HP (53.8 kW) at 9,000 rpm while maximum torque reaches 63.5 Nm (46.8 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 114.4 HP per liter and a 2,000 rpm working window between peak torque (7,000 rpm) and peak power (9,000 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 Raptor 650 measures 180 kg (397 lbs) dry, translating to a power-to-weight ratio of 0.41 HP/kg (2.44 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,438 mm (56.6 in) wheelbase engineered for balanced agility and highway composure. The 17.5-liter (4.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 200 km/h (124 mph).
