2018 Yamaha Serow 250 Technical Analysis & Specification Breakdown

Positioned in Yamaha's enduro - offroad motorcycle lineup, the 2018 Yamaha Serow 250 features a 249 cc (15.2 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 18 HP (13.1 kW) at 7,500 rpm while maximum torque reaches 19 Nm (14 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 72.3 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 Serow 250 measures 132 kg (291 lbs) wet (curb), translating to a power-to-weight ratio of 0.14 HP/kg (7.33 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 1,360 mm (53.5 in) wheelbase engineered for quick, flickable steering geometry. The 9.6-liter (2.5 US gal) fuel tank paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 384 km (239 miles) between fill-ups.
