Engineered by Kawasaki for the sport motorcycle segment, the 1992 Kawasaki KR1-S relies on a 249 cc (15.2 cu in) liquid-cooled twin, two-stroke powerplant. In factory specification, peak output is rated at 59.1 HP (43.2 kW) at 10,500 rpm while maximum torque reaches 40.2 Nm (29.7 lb-ft) at 10,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 237.3 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the KR1-S measures 131 kg (289 lbs) dry, translating to a power-to-weight ratio of 0.45 HP/kg (2.22 kg per horsepower). Rider ergonomics and chassis geometry center around a 755 mm (29.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,365 mm (53.7 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 219 km/h (136 mph).
