The ATV with a winning pedigree of power, suspension and big comfort.
The middleweight choice in Kawasakis V-twin powered sport-utility all-terrain vehicle (ATV) family, the Brute Force® 650 4x4i offers refined power and handling. It combines a plush ride courtesy of its competent front and rear independent suspension with a superb four-wheel drive system and a durable and powerful 633cc V-twin engine to deliver a knock-out blow to its challengers.
Thanks to its 90-degree, liquid-cooled four-stroke V-twin engine, this ATV shines when the going gets tough. With ample low-to-mid range torque and high rpm power to meet challenges presented by the adventure enthusiasts and sportsmen. Less weight is always a good thing. To keep the pounds off, Kawasaki engineers used aluminum in the construction of the front exhaust pipe cover, two-piece center exhaust pipe cover, and the muffler cover. Among the other features designed into the Brute Force 650 4x4i to amplify its power-to-weight ratio are drilled transmission gears to lower their overall weight.
The Brute Force 650 4x4i gets the power from its V-twin engine to the wheels through a fully automatic, dual range continuously variable transmission (CVT). With low and high forward, neutral and reverse gears, this dependable transmission functions seamlessly, providing excellent control for both low- and high-speed work or recreational riding. Additionally, with the brakes applied it can be started in any gear.
Two- or four-wheel drive is selectable by simply pressing a handlebar-mounted button. In four-wheel drive, the rider can manage the amount of power to both front wheels with Kawasakis Variable Front Differential Control by simply pulling a small lever on the left handlebar. This is a definite advantage for riders traversing deep mud, slippery uphill trails or large objects such as logs or rocks.
The optimized caster angle for the front A-arms means the Brute Force 650 4x4i has light and responsive steering as well as excellent ground-following abilities. Shock absorber spring rates and initial preload settings for both front and rear are aimed at excellent ride comfort and are enhanced via the plush urethane seat foam.
It may be the slightly smaller one in Kawasakis stable of IRS-equipped ATVs, but it doesnt sacrifice anything in the looks department. Like its brethren, the rugged, take-on-anything styling of the Brute Force 650 4x4i will both attract onlookers and satisfy owners.
Stopping the 650 4x4i is a combination of dual 200mm front discs and Kawasakis sealed, oil-bathed, multi-disc rear brake system. As an integrated part of the shaft drive, the enclosed rear braking system is sealed in the aluminum swingarm where it operates in an oil bath. This protects the brake pads 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 engines compression to help slow the Brute Force 650 4x4i under certain conditions.
The able ATV can pull a hefty 1,250 pounds, and it can carry a combined 264 pounds on its front and rear racks. Owners can expand the versatility of their Brute Force ATV via the extensive line of Authentic Kawasaki Accessories, available through Kawasaki dealers.
