Technical Overview
2011 Kawasaki Z 750 R Technical Analysis & Specification Breakdown
At the heart of the 2011 Kawasaki Z 750 R naked motorcycle, Kawasaki features a 748 cc (45.6 cu in) liquid-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 104.2 HP (76.1 kW) at 10,500 rpm while maximum torque reaches 78 Nm (57.5 lb-ft) at 8,000 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 139.3 HP per liter and a 2,500 rpm working window between peak torque (8,000 rpm) and peak power (10,500 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 Z 750 R measures 224 kg (494 lbs) dry, translating to a power-to-weight ratio of 0.47 HP/kg (2.15 kg per horsepower). Rider ergonomics and chassis geometry center around a 825 mm (32.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,440 mm (56.7 in) wheelbase engineered for balanced agility and highway composure. The 18.5-liter (4.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
