DT 125 R

1997 Yamaha DT 125 R Technical Analysis & Specification Breakdown

Engineered by Yamaha for the enduro - offroad motorcycle segment, the 1997 Yamaha DT 125 R relies on a 125 cc (7.6 cu in) single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 12 HP (8.8 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 96 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 0.11 HP/kg (9.08 kg per horsepower). Rider ergonomics and chassis geometry center around a 900 mm (35.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control.
