Combining impressive power and a sensible price, the Brute Force® 650 4x4 ATV offers outstanding value. The fact that its well-balanced V-twin, capable 4x4 system and nimble handling are offered for about the same price as the 500cc crowd makes it a favorite with practical minded riders who demand premium performance.

The 633cc 90-degree V-twin engine gives the rider industry-leading torque and a smooth power delivery that’s unrivaled by the competition. Dual 32mm Keihin carburetors draw fresh air from a snorkel intake located high in the frame near the steering head, reducing the amount of contaminants entering the intake.

The robust V-twin engine is mated to the Kawasaki Automatic Powerdrive System (KAPS) continuously variable transmission (CVT). With low and high range, neutral and reverse, this dependable transmission functions seamlessly, providing excellent control for both low- and high-speed work or recreational riding. Additionally, the Brute Force 650 4x4 can be started in any gear, as long as one of the brakes is applied.

Press Release

Power is delivered to the wheels through dependable, low-maintenance shaft drive contained in a lightweight aluminum swingarm. The rider can select two- or four-wheel drive operation via a switch conveniently mounted on the right handle bar. In normal four-wheel drive mode, the front wheels provide extra traction for adverse terrain, while the limited-slip differential allows the rider to make tight turns and reduces steering effort.

When maximum traction is needed, the rider can utilize Kawasaki’s Variable Front Differential Control by pulling a lever on the left handlebar to send power to both front wheels. This is a definite advantage for riders encountering deep mud and slippery uphill trails or when traversing over large objects such as logs or rocks.

The cutting-edge Brute Force 650 4x4 braking system design is a combination of dual front disc brakes with dual-piston calipers and Kawasaki’s sealed, oil-bathed, multi-disc rear brake system. As an integrated part of the shaft drive, the rear braking system is sealed in the aluminum swingarm where it operates in an oil bath. This protects the brake from mud, dust and debris, and is virtually maintenance-free.

Enhancing the high-performance brakes is the Kawasaki Engine Brake Control system, which electronically monitors ground speed and uses the engine’s compression to help slow the Brute Force ATV under certain conditions.

Plush and controlled rides are Kawasaki’s 4x4 ATV forte and the Brute Force 650 4x4 exemplifies this specialty. It does this with a MacPherson strut front suspension with 6.7 inches of travel and an aluminum swingarm featuring a shock with adjustable preload, a piggy-back reservoir and 7.2 inches of travel for the rear suspension duties.

Additional comfort is provided by a large seat and adjustable footpegs mounted atop full-size floorboards. To help reduce unsprung weight and further enhance the smooth ride, the Brute Force rolls on aluminum wheels.

The modern, aggressively angled lines and high gloss appearance of the Thermoplastic Olefin scratch-resistant bodywork are complemented by bright cat-eye headlights. The fully digital instrumentation includes speedometer, odometer, dual resettable trip meters, clock, hour meter, fuel gauge and 2x4/4x4 indicators.

Leading the conveniences on the Brute Force 650 4x4 is a DC power outlet to provide quick and easy power for electrical accessories. A space inside the front guard easily accommodates a 3,000-pound capacity winch from Warn or Superwinch.

The front and rear steel racks on the Brute Force 650 4x4 can carry a total of 264 pounds of cargo; a hitch bracket enables the ATV to tow up to 1,250 pounds. Owners can expand the versatility of their Brute Force ATV via the extensive line of Authentic Kawasaki Accessories, available through Kawasaki dealers.

As with all off-highway vehicle recreation, Kawasaki encourages ATV riders to ride responsibly and to respect the environment. Kawasaki will pay first-time buyers of a new Kawasaki ATV $100 for completing an ATV rider safety course conducted by the ATV Safety Institute (ASI). Interested consumers can call ASI toll-free at 800-887-2887.
