NSR 125 R

2001 Honda NSR 125 R Technical Analysis & Specification Breakdown

Engineered by Honda for the sport motorcycle segment, the 2001 Honda NSR 125 R pairs a 124.8 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 9,500 rpm while maximum torque reaches 15 Nm (11.1 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 120.2 HP per liter and a 1,500 rpm working window between peak torque (8,000 rpm) and peak power (9,500 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 NSR 125 R measures 132 kg (291 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (8.8 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,345 mm (53 in) wheelbase engineered for quick, flickable steering geometry. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 125 km/h (78 mph).
