Kawasaki Brute Force 750 4x4i, 2009

Kawasaki Brute Force 750 4x4i, 2009

The Brute Force 750 4x4i combines sport riding performance, utility capability, and the fit and finish one would expect from a flagship model–all built on an independent suspension chassis.

The perfect union of fuel injected, big-bore power and 4x4 ATV capability
The leader of Kawasaki’s V-twin powered, sport-utility all-terrain vehicle (ATV) pack, the Brute Force® 750 4x4i retains its top status for 2009 by mating a hard-charging digital fuel injected V-twin engine to the plush ride supplied by its competent front and rear fully independent suspension and superb four-wheel drive system. Wrapped in aggressive bodywork, it’s the perfect choice for adventure enthusiasts and sportsmen alike.

The Brute Force 750 4x4i is driven by a powerful 90-degree, four-stroke, fuel injected V-twin engine. The 749cc, twin Electrofusion-plated aluminum cylinders are fed via 36mm throttle bodies controlled by a 32-bit CPU, which delivers the correct mixture based on coolant temperature, air intake temperature, throttle position, air intake pressure, vehicle speed and crankshaft angle. Its high-pressure fuel pump is located inside the tank and has a unique reservoir chamber at the bottom to help ensure air does not get into the fuel system.

A Brute Force 750 4x4i gets the power from its V-twin engine to the wheels through a continuously variable transmission (CVT) with low or high range, and reverse. The rider is able to select two- or four-wheel-drive operation simply by pressing a button on the handlebar. In four-wheel-drive mode, the Brute Force ATV utilizes a limited-slip front differential, which eases steering effort under most riding conditions. The rider can also engage the handlebar mounted Variable Front Differential Control lever to manage torque delivery to the right and left front wheels for maximum traction.

The front drive shafts of the Brute Force feature Cardan joints –an industry first. Similar to U-joints, Cardan joints help absorb torque fluctuations to the drive shaft, and the lightweight design helps to reduce vibration. The small and compact rear final gear case and sealed rear braking system were designed in conjunction with the IRS and are extremely rugged and efficient.

Dual front discs and Kawasaki’s highly acclaimed sealed rear braking system bring the Brute Force 750 4x4i to a quick halt. Completely sealed, the rear braking system’s components are protected from mud, dust and debris. Its compact size also provides more ground clearance than a conventional rear disc brake system. Enhancing the highly effective braking is the engine’s Kawasaki Engine Brake Control, which helps slow the ATV under certain conditions.

Ride comfort on the Brute Force 750 4x4i doesn’t come at the expense of sport performance. Dual-rate springs for the front and rear suspension permit the best of both worlds. A soft initial spring rate for the bumps at slower speeds and a firmer second rate to handle higher speeds comes into play as the springs are further compressed. Complimenting the suspension, the urethane foam in the seat is firm enough to be supportive yet provide plenty of comfort for long hours in the saddle.

The Brute Force 750 4x4i utilizes a simple, yet sturdy double-cradle tubular steel frame with front dual A-arms and IRS. The front dual A-arms feature adjustable shocks with 6.7 inches of travel, while the IRS employs a leading torsion bar and provides 7.9 inches of travel. A combination of needle bearings and ball joints in the lower rear A-arms gives the IRS unrivaled suspension action, stability and excellent rider comfort.

As if performance wasn’t enough, the Brute Force 750 4x4i can turn heads with looks alone with its polished 12-inch wheels. Clad in aggressive tires, the eye-catching wheels help give the ATV its 9.7 inches of ground clearance and transfer the awesome power of the V-twin engine to the ground.

The 750 4x4i’s front bumper is designed for easily manhandling the Brute Force when the need arises. Behind the bumper is the strong and tough angular bodywork constructed of high-gloss and scratch-resistant Thermo-Plastic Olefin (TPO). Underneath this bodywork is a factory-installed plastic conduit for easy winch installation.

The chassis balance is further optimized by the large five-gallon fuel tank beneath the seat. Keeping the weight in check are aluminum footpegs on the full-sized floorboards and lightweight cargo racks that can carry a combined weight of 264 pounds. The capable Brute Force can also tow 1,250 pounds.
