2017 Kawasaki J300 Technical Analysis & Specification Breakdown

Built around Kawasaki's scooter motorcycle platform, the 2017 Kawasaki J300 pairs a 299 cc (18.2 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 28 HP (20.4 kW) at 7,750 rpm while maximum torque reaches 28.7 Nm (21.2 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 93.6 HP per liter and a 1,250 rpm working window between peak torque (6,500 rpm) and peak power (7,750 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 J300 measures 191 kg (421 lbs) wet (curb), translating to a power-to-weight ratio of 0.15 HP/kg (6.82 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,555 mm (61.2 in) wheelbase engineered for planted straight-line stability. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
