Technical Overview
1989 Honda NSR 250 R Technical Analysis & Specification Breakdown
Positioned in Honda's sport motorcycle lineup, the 1989 Honda NSR 250 R pairs a 249 cc (15.2 cu in) liquid-cooled v2, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 45 HP (32.8 kW) at 9,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 180.7 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the NSR 250 R measures 131 kg (289 lbs) dry, translating to a power-to-weight ratio of 0.34 HP/kg (2.91 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 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 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 209 km/h (130 mph).
