At the heart of the 2017 Kawasaki Z300 naked motorcycle, Kawasaki utilizes a 296 cc (18.1 cu in) liquid-cooled twin, four-stroke layout. In factory specification, peak output is rated at 39 HP (28.5 kW) at 11,000 rpm while maximum torque reaches 27 Nm (19.9 lb-ft) at 10,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 131.8 HP per liter and a 1,000 rpm working window between peak torque (10,000 rpm) and peak power (11,000 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 Z300 measures 168 kg (370 lbs) wet (curb), translating to a power-to-weight ratio of 0.23 HP/kg (4.31 kg per horsepower). Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,405 mm (55.3 in) wheelbase engineered for quick, flickable steering geometry. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
