Technical Overview
2004 Yamaha TT-R125 LW E Technical Analysis & Specification Breakdown
At the heart of the 2004 Yamaha TT-R125 LW E enduro - offroad motorcycle, Yamaha 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) at 6,500 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 78.4 HP per liter and a 1,500 rpm working window between peak torque (6,500 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 TT-R125 LW E measures 78 kg (172 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.04 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, combined with a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry.
