Built around Yamaha's enduro - offroad motorcycle platform, the 2011 Yamaha Serow 250 relies on a 249 cc (15.2 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 28.2 HP (20.6 kW) at 6,500 rpm while maximum torque reaches 20 Nm (14.8 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 113.3 HP per liter, 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 Serow 250 measures 115 kg (254 lbs) dry, translating to a power-to-weight ratio of 0.25 HP/kg (4.08 kg per horsepower). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
