The ultimate 4x4
performance king now fuel injected and even
better
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.
