2006 Kawasaki Brute Force 650 4X4i

Kawasaki’s introduction of the new Brute Forceâ„¢ 650 4x4i ATV has been smoothed by the tremendous success achieved by its slightly larger brethren, the Brute Force 750 4x4i. This economical new addition to the Kawasaki family of V-twin powered sport-utility all-terrain vehicles couples the luxurious ride inherent with front and rear independent suspension and the qualities of this durable and powerful 633cc engine.

Offering virtually the same power characteristics as the 750 4x4i, this new ATV entry 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 an all-new 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.

Its new 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.

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. Designers gave the Brute Force 650 4x4i a rugged, take-on-anything type of appearance with a new 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.

Engine

  • 633cc four-stroke, liquid-cooled V-twin
  • All-aluminum cylinders with Electrofusion(KP) coating are durable and help the engine produce more power. The aluminum bores eliminate cast iron cylinders liners to improve heat dispersion and reduce weight.
  • V-twin design and oversquare bore and stroke help produce high torque with a broad, user-friendly curve.
  • 90-degree cylinder offset produces perfect primary balance to minimize vibration for rider comfort.

4-Valve Cylinder Head (KP)

  • Efficiency and more power.
  • 4 valves provide maximum valve area for optimal flow.
  • Boosts low-end torque.

Twin Downdraft Carburetors

  • Twin CVKR-34 carburetors are 2mm larger than the Brute Force 650 4x4 and are now mounted in a downdraft position, providing the fuel mixture with a straight shot into the combustion chamber.

Liquid Cooling

  • Larger-capacity radiator provides consistent cooling, allowing closer engine tolerances, quieter running, and ultimate durability.
  • Thermostatically-controlled fan keeps engine cool even at very low vehicle speeds.
  • Snorkel Air Intake(KP)
  • Airbox design provides easy access to simplify maintenance.
  • Oval-type air filter provides large intake area and reduces dust build-up on the filter.

  • The drive converter shaft is hard chrome finished for durability.
  • Shifting timed in higher rpm range for snappy throttle response and class-leading acceleration.
  • Strong CVT belt handles the increased power.
  • Water drain hole in drive pulley cover prevents mud from clogging release bearing for added durability.
  • Belt Check indicator lamp is easy to see.
  • Continuously variable transmission is fully automatic.

Kawasaki Engine Break Control (KP)

  • Engine brake actuator controller maintains proper adjustment during servicing and maintains reliability of engine brake activation.

the 650 outright rocks!!!!!

was just wondering on how to keep seed from clogin my radiator and causing the oil light to start blinking my fan stays on like all the time is there any thing i could do to prevent this without affecting where i ride at cause i hate having to ride ten miles to get back home to take the hose to it

I keep looking at the bf 650i...took one for a test drive but what can you learn in the parking lot...it seems fast but what about mid to high speed comfort? I had a 98 polaris 400 2 stroke explorer 4x4 and when they stopped production of this model in 2002 I went out and purchased another one....I still think its one of the best allaround ATV,s ever made. great power to weight ratio, that 2 stroke punch and great comfort even at speed...I like the new larger polaris line up but to get the speed I want the machines are 750lbs... will the bf 650i fill my comfort requirement and handle as well as my 02 explorer at high speeds?

thanks Dean from nh.... 46 yrs old and dirt riding since I was 8
