TDR 125

1997 Yamaha TDR 125 Technical Analysis & Specification Breakdown

At the heart of the 1997 Yamaha TDR 125 allround motorcycle, Yamaha pairs a 125 cc (7.6 cu in) single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 15 HP (10.9 kW) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 120 HP per liter, 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 TDR 125 measures 122 kg (269 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.13 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams.
