2006 Cagiva Raptor 650 i.e. Technical Analysis & Specification Breakdown
At the heart of the 2006 Cagiva Raptor 650 i.e. naked motorcycle, Cagiva features a 644.1 cc (39.3 cu in) liquid-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 70 HP (51.1 kW) at 9,000 rpm while maximum torque reaches 63.5 Nm (46.8 lb-ft) at 7,400 rpm, transferring power to the rear wheel through a 6-speed gearbox. With a specific output of 108.7 HP per liter and a 1,600 rpm working window between peak torque (7,400 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 i.e. measures 180 kg (397 lbs) dry, translating to a power-to-weight ratio of 0.39 HP/kg (2.57 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.
