At the heart of the 2004 Yamaha XVS 650 DragStar custom - cruiser motorcycle, Yamaha pairs a 649 cc (39.6 cu in) air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 39.4 HP (28.8 kW) at 6,500 rpm while maximum torque reaches 50.9 Nm (37.5 lb-ft) at 3,000 rpm. With a specific output of 60.7 HP per liter and a 3,500 rpm working window between peak torque (3,000 rpm) and peak power (6,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the XVS 650 DragStar measures 220 kg (485 lbs) dry, translating to a power-to-weight ratio of 0.18 HP/kg (5.58 kg per horsepower). Rider ergonomics and chassis geometry center around a 695 mm (27.4 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,610 mm (63.4 in) wheelbase engineered for planted straight-line stability.
