Positioned in Yamaha's allround motorcycle lineup, the 2001 Yamaha TDR 125 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 while maximum torque reaches 14.7 Nm (10.8 lb-ft) 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 128 kg (282 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.53 kg per horsepower). Rider ergonomics and chassis geometry center around a 850 mm (33.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,405 mm (55.3 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 105 km/h (65 mph).
