At the heart of the 2011 Yamaha DS250 Drag Star Two-Fifty 250 custom - cruiser motorcycle, Yamaha features a 249 cc (15.2 cu in) air-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 20.8 HP (15.2 kW) at 10,000 rpm while maximum torque reaches 20.7 Nm (15.3 lb-ft) at 2,100 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 83.5 HP per liter and a 7,900 rpm working window between peak torque (2,100 rpm) and peak power (10,000 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 DS250 Drag Star Two-Fifty 250 measures 159 kg (351 lbs) wet (curb), translating to a power-to-weight ratio of 0.13 HP/kg (7.64 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. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
