Positioned in Yamaha's scooter motorcycle lineup, the 2008 Yamaha X-Max 250 utilizes a 249.8 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 20.9 HP (15.3 kW) at 7,500 rpm while maximum torque reaches 21.3 Nm (15.7 lb-ft) at 6,500 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 83.7 HP per liter and a 1,000 rpm working window between peak torque (6,500 rpm) and peak power (7,500 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 X-Max 250 measures 165 kg (364 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.89 kg per horsepower). Rider ergonomics and chassis geometry center around a 755 mm (29.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,545 mm (60.8 in) wheelbase engineered for planted straight-line stability. The 12.5-liter (3.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
