1999 Kawasaki ZRX 1100 Technical Analysis & Specification Breakdown

Positioned in Kawasaki's naked motorcycle lineup, the 1999 Kawasaki ZRX 1100 features a 1052 cc (64.2 cu in) liquid-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 98 HP (71.5 kW) at 8,000 rpm while maximum torque reaches 92 Nm (67.9 lb-ft) at 6,200 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 93.2 HP per liter and a 1,800 rpm working window between peak torque (6,200 rpm) and peak power (8,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the ZRX 1100 measures 245 kg (540 lbs) wet (curb), translating to a power-to-weight ratio of 0.4 HP/kg (2.5 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 1,450 mm (57.1 in) wheelbase engineered for balanced agility and highway composure. The 20-liter (5.3 US gal) fuel tank paired with a rated consumption of 7.1 L/100 km provides an estimated theoretical range of roughly 282 km (175 miles) between fill-ups, while factory top speed is listed at 221 km/h (137 mph).
