Engineered by Yamaha for the custom - cruiser motorcycle segment, the 2004 Yamaha XVS 125 DragStar features a 124 cc (7.6 cu in) air-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 12.9 HP (9.4 kW) at 10,000 rpm while maximum torque reaches 9.4 Nm (6.9 lb-ft) at 8,000 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 104 HP per liter and a 2,000 rpm working window between peak torque (8,000 rpm) and peak power (10,000 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 XVS 125 DragStar measures 144 kg (317 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.16 kg per horsepower). Rider ergonomics and chassis geometry center around a 670 mm (26.4 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,530 mm (60.2 in) wheelbase engineered for planted straight-line stability.
