Brute Force™ 650 4x4i
A blend of comfort, ability and ruggedness make this ATV a winner

Brute Force 650 4x4iWhether you are heading out into the great wide open for work or for pleasure, Kawasaki’s Brute Force™ 650 4x4i ATV is the perfect companion. This sport-utility all-terrain vehicle boasts a 633cc V-twin engine, with plentiful torque and a user-friendly power delivery. Independent front and rear suspension coupled with four-wheel-drive and an upright seating position creates a comfortable go anywhere ride in an affordable package.

This ATV will shine under the most grueling circumstances in both low-to-mid range rpm and high rpm ranges. The 90-degree, liquid-cooled four-stroke powerplant will be there to answer any needs posed by its target audience of adventure enthusiasts and sportsmen.

The engine features a bore and stroke of 80mm x 63mm, linerless aluminum cylinders based on its big brother’s, and a lightweight crankshaft.

Helping to lighten the load, engineers have used aluminum to replace steel in the construction of the front exhaust pipe cover, new two-piece center exhaust pipe cover, and the muffler cover. Transmission gears in the Brute Force 650 4x4i feature holes to lighten the overall weight and several other minor changes have been introduced to optimize the power-to-weight ratio.

ts chassis has a revised caster angle for the front A-arms—upper and lower—resulting in light and responsive steering as well as excellent ground-following abilities. Shock absorber spring rates and initial preload settings for both front and rear have been revised to improve ride comfort. Riding comfort was also considered when this unit was slated for a seat using a softer urethane foam cushion.

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

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

Brute Force 650 4x4It may be the slightly smaller one in Kawasaki’s stable of IRS-equipped ATVs, but it doesn’t sacrifice anything in the “looks” department. Designers gave the Brute Force 650 4x4i a rugged, take-on-anything type of appearance with a front guard design that will both attract onlookers and satisfy owners. It will come cloaked in either Woodsman Green, Aztec Red, or Realtree Hardwoods Green® HD™ camouflage.

Authentic Kawasaki Accessories for the 2006 Brute Force 650 4x4i are available through Kawasaki dealers or the can be purchased on the Internet at www.kawasaki.com.

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).
