Technical Overview
2012 Kawasaki Z750R Black Edition Technical Analysis & Specification Breakdown
At the heart of the 2012 Kawasaki Z750R Black Edition naked motorcycle, Kawasaki pairs a 748 cc (45.6 cu in) liquid-cooled in-line four, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 106 HP (77.4 kW) at 10,500 rpm while maximum torque reaches 78 Nm (57.5 lb-ft) at 8,300 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 141.7 HP per liter and a 2,200 rpm working window between peak torque (8,300 rpm) and peak power (10,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Z750R Black Edition measures 224 kg (494 lbs) wet (curb), translating to a power-to-weight ratio of 0.47 HP/kg (2.11 kg per horsepower). Rider ergonomics and chassis geometry center around a 815 mm (32.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, 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.
