Positioned in Yamaha's custom - cruiser motorcycle lineup, the 2007 Yamaha XVS 650 DragStar 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 50.1 Nm (37 lb-ft) at 5,100 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 60.7 HP per liter and a 1,400 rpm working window between peak torque (5,100 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 229 kg (505 lbs) dry, translating to a power-to-weight ratio of 0.17 HP/kg (5.81 kg per horsepower). Rider ergonomics and chassis geometry center around a 710 mm (28 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,625 mm (64 in) wheelbase engineered for planted straight-line stability. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
