Brute Force™ 650 4x4i



Go anywhere ability and toughness mated with big comfort equals a winner.

Kawasaki's Brute Force® 650 4x4i ATV is the hidden gem in the Kawasaki family of V-twin powered sport-utility all-terrain vehicles. It combines a plush ride that is a natural outcome of its front and rear independent suspension with the superb qualities of its four-wheel drive and durable and powerful 633cc engine to be a “win-win” for owners.

Thanks to its 90-degree, liquid-cooled four-stroke powerplant, this ATV will shine under the most grueling circumstances in both low-to-mid range and high rpm ranges and will be ready to answer any requests by its target audience of adventure enthusiasts and sportsmen. The engine has a bore and stroke of 80mm x 63mm, linerless aluminum cylinders based on its big brother's and a lightweight crankshaft.

Less weight is always a good thing, so 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 optimize the power-to-weight ratio are drilled transmission gears to lighten their overall weight.

The chassis has an optimized caster angle for the front A-arms—upper and lower—to provide 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 also set for excellent ride comfort, which was also boosted on the Brute Force 650 4x4i via its softer urethane seat foam cushion.

The Brute Force 650 4x4i gets the power from its V-twin engine transfered to the wheels through a dual range continuously variable transmission (CVT) featuring high, low and reverse. Two- or four-wheel drive is selectable by the rider simply pressing a handlebar-mounted button.

Stopping the 650 4x4i are dual 200mm front discs and an enclosed wet multi-plate rear brake system. The able ATV has a towing capacity of a hefty 1,250 pounds, and it can carry a combined 264 pounds on its front and rear racks.

It may be the slightly smaller one in Kawasaki's stable of IRS-equipped ATVs, but it doesn't sacrifice anything in the “looks” department. Like its brethren, the Brute Force 650 4x4i sports a rugged, take-on-anything appearance with a front guard design that will both attract onlookers and satisfy owners. It can be clad in Woodsman Green, Super Black, Sunbeam Red, Candy Thunder Blue or Realtree Hardwoods Green® HD™ camouflage.
