Engineered by Yamaha for the enduro - offroad motorcycle segment, the 2006 Yamaha TT-R125 - LW utilizes a 123.7 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 9.7 HP (7 kW) at 8,000 rpm while maximum torque reaches 9.9 Nm (7.3 lb-ft), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 78.4 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the TT-R125 - LW measures 84 kg (185 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.66 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,250 mm (49.2 in) wheelbase engineered for quick, flickable steering geometry. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
