Technical Overview
2011 Suzuki ST 250E Technical Analysis & Specification Breakdown
Built around Suzuki's allround motorcycle platform, the 2011 Suzuki ST 250E utilizes a 249 cc (15.2 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 18.8 HP (13.7 kW) at 7,500 rpm while maximum torque reaches 21 Nm (15.5 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 75.5 HP per liter and a 2,000 rpm working window between peak torque (5,500 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 ST 250E measures 146 kg (322 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.77 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,375 mm (54.1 in) wheelbase engineered for quick, flickable steering geometry. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
