Built around Kawasaki's atv motorcycle platform, the 2017 Kawasaki Brute Force 650 4x4i utilizes a 633 cc (38.6 cu in) liquid-cooled v2, four-stroke layout. In factory specification, peak output is rated at 47 HP (34.3 kW) at 7,500 rpm while maximum torque reaches 51.4 Nm (37.9 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a automatic gearbox and shaft drive (cardan) final drive. With a specific output of 74.2 HP per liter and a 2,000 rpm working window between peak torque (5,500 rpm) and peak power (7,500 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 Brute Force 650 4x4i measures 298 kg (657 lbs) wet (curb), translating to a power-to-weight ratio of 0.16 HP/kg (6.34 kg per horsepower). Rider ergonomics and chassis geometry center around a 904 mm (35.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,285 mm (50.6 in) wheelbase engineered for quick, flickable steering geometry. The 20.44-liter (5.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
