At the heart of the 2017 Kawasaki Z800 naked motorcycle, Kawasaki utilizes a 806 cc (49.2 cu in) liquid-cooled in-line four, four-stroke layout. In factory specification, peak output is rated at 113 HP (82.5 kW) at 10,200 rpm while maximum torque reaches 83 Nm (61.2 lb-ft) at 8,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 140.2 HP per liter and a 1,700 rpm working window between peak torque (8,500 rpm) and peak power (10,200 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Z800 measures 227 kg (500 lbs) wet (curb), translating to a power-to-weight ratio of 0.5 HP/kg (2.01 kg per horsepower). Rider ergonomics and chassis geometry center around a 834 mm (32.8 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,445 mm (56.9 in) wheelbase engineered for balanced agility and highway composure. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
