Kawasaki Brute Force 750 4x4i Offroaders ATV World

Kawasaki’s alpha dog Brute Force® 750 4x4i all-terrain vehicle returns for 2008 to terrorize the competition with its awe-inspiring V-twin engine gaining a digital fuel injection system and the chassis receiving a host of updates in the suspension and comfort departments.

Built with adventure enthusiasts and sportsmen in mind, the Brute Force 750 4x4i is wrapped in aggressive bodywork, driven by a powerful V-twin engine and utilizes a fully independent rear suspension (IRS) system. And for 2008 the flagship of the Brute Force line not only gains EFI but also features revised suspension settings, new seat urethane, increased sealed storage, new bumper design, polished wheels, lighter aluminum footpegs, and stronger axle boots. The newest version also now has factory-installed plastic conduit for easy winch installation.

Adding fuel injection to Kawasaki’s largest and most powerful 90-degree, four-stroke V-twin engine, basically gives riders more of a good thing. Now the 749cc, twin Electrofusion-plated aluminum cylinders get 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. The reduced spring rate for the throttle return springs and ball bearings in the throttle bodies translates into lighter feel at the throttle lever and less rider fatigue.

Add instantaneous fuel delivery and the engine response from the four valves per cylinder engine is sharper than ever –sure to be a hit with sport riders. The 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.

The high-efficiency radiator is mounted high in the chassis where it is best shielded from mud and debris.

The Brute Force 750 4x4i transfers power from its V-twin engine to the wheels through a continuously variable transmission (CVT) featuring high and low range, plus reverse, and by  pressing a button on the handlebar, the rider can also select two- or four-wheel-drive operation. In four-wheel-drive mode, the Brute Force utilizes a limited-slip front differential, which eases steering effort under most riding conditions. The rider can also engage the Variable Front Differential Control to deliver torque equally 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 its lightweight design helps to reduce vibration. The rear final gear case and sealed rear braking system have been designed in conjunction with the IRS. Smaller and more compact, the gear case is extremely rugged and efficient.

Increased ride comfort on the new 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 rate handles the bumps at slower speeds is followed by a firmer second spring rate that comes into play as the springs are further compressed to handle higher sport speeds. Complimenting the revised suspension settings is new seat urethane that boosts rider comfort to new levels. The seat feels softer initially, but is firm enough to be supportive and 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 that features front dual A-arms and IRS. The front dual A-arms have 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 and high stability and excellent rider comfort.

Dual front discs and Kawasaki’s highly acclaimed sealed rear braking system provide maximum stopping power for the Brute Force 750 4x4i. The rear braking system’s internal components are completely sealed to protect them from mud, dust and debris, and its compact size provides for more ground clearance than a conventional rear disc brake system. Enhancing the highly effective braking even further is the engine’s Kawasaki Engine Brake Control, which helps slow the ATV under certain conditions.

As if its performance wasn’t enough, the Brute Force 750 4x4i can turn heads with looks alone with its new polished 12-inch wheels and their easily buffed surface and more robust folded lip design. The eye-catching wheels are clad in aggressive tires that 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 new look up front is a benefit of the Brute Force’s revised bumper design, which offers a more effective handgrip position for manhandling the big Kawasaki when the need arises. Behind the bumper are the big, strong and tough-looking bodywork and front grille that match the aggressive angular lines of its bodywork. This plastic is made of Thermo-Plastic Olefin (TPO), and has a high-gloss appearance and is scratch-resistant.

Rider position is upright and comfortable, enhancing the rider’s ability to interact with the Brute Force 750 4x4i and scan the horizon and the easy to read automotive-style instrument panel. Other features include the ATV industry’s first four-bulb headlights, and a new waterproof storage box in the left front fender, complementing the storage compartment in the right front fender. 

Keeping the weight in check are new aluminum footpegs on the full-sized floorboards and smaller and lighter cargo racks. The new Brute Force ATV also features a subtlety more compact design, with almost one half inch less in width and height than last year’s machine. The chassis balance is further optimized by positioning the large 5.4-gallon fuel tank beneath the revised seat.
It can carry a combined weight of 264 pounds on its cargo racks and has a tow rating of 1,250 pounds.

Authentic Kawasaki Accessories for the 2008 Brute Force 750 4x4i are available through Kawasaki dealers.

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). Interested consumers can call ASI toll-free at 800-887-2887.
