TW 125

2000 Yamaha TW 125 Technical Analysis & Specification Breakdown

At the heart of the 2000 Yamaha TW 125 enduro - offroad motorcycle, Yamaha pairs a 124 cc (7.6 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 12 HP (8.8 kW) at 9,000 rpm while maximum torque reaches 10 Nm (7.4 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 96.8 HP per liter and a 1,000 rpm working window between peak torque (8,000 rpm) and peak power (9,000 rpm), 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 TW 125 measures 118 kg (260 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (9.83 kg per horsepower). Rider ergonomics and chassis geometry center around a 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
