Thanks to is rugged and unstoppable character, the Kawasaki Brute Force 650 4x4i has managed to conquer a lot of fans and many consider it one of the most capable ATVs in its class. Its workhorse capabilities and independent front and rear suspension combine to ably handle work and play.

The ATV is propelled by a four-stroke, V-twin, liquid-cooled, SOHC, four-valve engine which has a displacement of 633cc. The engine offers a hefty pulling power of 1,250 pounds and can carry a combined 264 pounds on its front and rear racks.

The stopping power is offered by a smart combination of dual 200mm front discs and Kawasaki’s sealed, oil-bathed, multi-disc rear brake system. 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 650 4x4i under certain conditions.

Its 633cc 90-degree V-twin engine pumps out plenty of low-to-mid range torque and high rpm power, exactly what adventure enthusiasts and outdoor sportsmen demand. A fully automatic, dual-range continuously variable transmission transmits power to the ground. With low and high forward, reverse and neutral gears, this sturdy transmission supplies excellent control for both low- and high-speed riding. Two- or four-wheel drive is selectable by simply pressing a handlebar-mounted button. In four-wheel drive mode, the rider can manage the amount of power to both front wheels with Kawasaki’s Variable Front Differential Control by pulling a small control lever on the left handlebar. This is a definite advantage for traversing deep mud, slippery uphill trails or large objects such as logs or rocks. Prudent use of aluminum in the construction of the front exhaust pipe cover, two-piece center exhaust pipe cover, and the muffler cover helps keep the weight down. Other features designed to enhance the Brute Force 650 4x4i’s power-to-weight ratio include drilled transmission gears to lower their overall weight. An optimized caster angle for the front A-arms provides both light and responsive steering and excellent ground-following abilities. The 650 4x4i shock absorber spring rates and initial preload settings for both front and rear are set to deliver excellent ride comfort. Further ride enhancement comes from the plush urethane seat foam. Like its Independent Rear Suspension-equipped Kawasaki brethren, the rugged, take-on-anything styling of the Brute Force 650 4x4i will both attract onlookers and satisfy owners. It shares front/rear racks, skid plate and head light cover with its larger sibling. Designed to allow easily manhandling of the Brute Force when the need arises, the 650 4x4i sports a steel front bumper.
