Built around Yamaha's enduro - offroad motorcycle platform, the 2007 Yamaha TT-R 125 LWE relies on a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. 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. With a specific output of 78.2 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-R 125 LWE 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 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance.
