DT 125 R

2000 Yamaha DT 125 R Technical Analysis & Specification Breakdown

At the heart of the 2000 Yamaha DT 125 R enduro - offroad motorcycle, Yamaha relies on a 124 cc (7.6 cu in) single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 13 HP (9.5 kW) at 7,000 rpm while maximum torque reaches 13 Nm (9.6 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 104.8 HP per liter and a 500 rpm working window between peak torque (6,500 rpm) and peak power (7,000 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 DT 125 R measures 109 kg (240 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.38 kg per horsepower). Rider ergonomics and chassis geometry center around a 885 mm (34.8 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control.
