Serow 225 WE

2002 Yamaha Serow 225 WE Technical Analysis & Specification Breakdown

Positioned in Yamaha's enduro - offroad motorcycle lineup, the 2002 Yamaha Serow 225 WE relies on a 223 cc (13.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 20 HP (14.6 kW) at 8,000 rpm while maximum torque reaches 19 Nm (14 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 89.7 HP per liter and a 1,000 rpm working window between peak torque (7,000 rpm) and peak power (8,000 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 Serow 225 WE measures 108 kg (238 lbs) dry, translating to a power-to-weight ratio of 0.19 HP/kg (5.4 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, combined with a 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
