ZRX 1200 S

2001 Kawasaki ZRX 1200 S Technical Analysis & Specification Breakdown

Positioned in Kawasaki's sport touring motorcycle lineup, the 2001 Kawasaki ZRX 1200 S relies on a 1164 cc (71 cu in) in-line four, four-stroke powerplant. In factory specification, peak output is rated at 122 HP (89.1 kW) at 8,500 rpm while maximum torque reaches 112 Nm (82.6 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 104.8 HP per liter and a 1,500 rpm working window between peak torque (7,000 rpm) and peak power (8,500 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 ZRX 1200 S measures 227 kg (500 lbs) dry, translating to a power-to-weight ratio of 0.54 HP/kg (1.86 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,465 mm (57.7 in) wheelbase engineered for balanced agility and highway composure. The 19-liter (5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 230 km/h (143 mph).
