XVS Drag Star

1999 Yamaha XVS Drag Star Technical Analysis & Specification Breakdown

Engineered by Yamaha for the custom - cruiser motorcycle segment, the 1999 Yamaha XVS Drag Star utilizes a 649 cc (39.6 cu in) air-cooled v2, four-stroke layout. In factory specification, peak output is rated at 40 HP (29.2 kW) at 6,500 rpm while maximum torque reaches 51 Nm (37.6 lb-ft) at 3,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 61.6 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 Drag Star measures 230 kg (507 lbs) wet (curb), translating to a power-to-weight ratio of 0.17 HP/kg (5.75 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. The 16-liter (4.2 US gal) fuel tank paired with a rated consumption of 5.6 L/100 km provides an estimated theoretical range of roughly 286 km (178 miles) between fill-ups, while factory top speed is listed at 150 km/h (93 mph).
