2021 Kawasaki W800 Street Technical Analysis & Specification Breakdown

Built around Kawasaki's allround motorcycle platform, the 2021 Kawasaki W800 Street pairs a 773 cc (47.2 cu in) air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 46.9 HP (34.3 kW) at 6,000 rpm while maximum torque reaches 62.9 Nm (46.4 lb-ft) at 4,800 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 60.7 HP per liter and a 1,200 rpm working window between peak torque (4,800 rpm) and peak power (6,000 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 W800 Street measures 221 kg (487 lbs) wet (curb), translating to a power-to-weight ratio of 0.21 HP/kg (4.71 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,465 mm (57.7 in) wheelbase engineered for balanced agility and highway composure.
