2012
Brute Force 750 Fuel injected V-twin power
& 4x4 muscle
The Brute Force® 750 4x4i ATV received
a comprehensive round of upgrades for
the 2012 model year, with significant
new features like a more-powerful V-twin
engine, new double-wishbone front suspension,
six-spoke cast alloy wheels, new bodywork
featuring wide-stance styling cues. Like
always, dual-range four-wheel drive and
a highly maneuverable chassis provide
amazing traction, handling and utility.
Thanks to revised tuning, a new cylinder
head and increased compression ratio,
the 2012 Brute Force 750 4x4i’s
upgraded four-stroke fuel injected 90-degree
749cc V-twin engine offers more power
than ever, with enhanced low-rpm performance.
The twin cylinders are fed via 36mm throttle
bodies that are controlled by a 32-bit
CPU. The system monitors coolant temperature,
air intake temperature, air intake pressure,
throttle position, vehicle speed and crankshaft
angle to deliver the optimum fuel mixture.
Instantaneous fuel delivery and crisp
engine response help make the eight-valve
engine a hit with sport riders. Despite
the big power from the engine, a light
feel at the throttle lever helps reduce
rider fatigue. This is achieved by using
a low spring rate for the throttle return
springs and ball bearings in the throttle
bodies.
A new larger radiator is placed high
in the chassis for optimum protection
against mud and debris, while a new larger
radiator fan and larger-diameter cooling
hoses and pipes help maximize cooling
performance. A self-repairing circuit
breaker and dedicated fuse for the new
fan also help keep things cool when the
going gets tough.
For 2012, the entire steering assembly
was repositioned so the bottom of the
steering shaft no longer connects directly
to the front differential housing. Movement
of the differential due to throttle inputs
in 4x4 mode no longer affect the steering
assembly, this isolation provides significantly
smoother handling.
An upgraded fully automatic, dual-range
continuously variable transmission (CVT)
is mated to the powerful V-twin engine.
A new high gear ratio and a thicker belt
made of stronger material contributes
to longer CVT belt life and reduced maintenance
requirements. Revised converter weight
and drive spring tuning offers improved
acceleration characteristics and increased
control during low-speed operation and
a new layout and revised placement of
the CVT air duct is more effective at
helping prevent the intrusion of water
and mud.
Two- or four-wheel drive operation is
selectable by simply pressing a button
on the handlebar. In four-wheel drive
mode, the Brute Force ATV utilizes the
limited-slip front differential to help
maintain steering response and ease steering
effort at the bars. The rider can manage
the amount of power to both front wheels
with Kawasaki’s Variable Front Differential
Control by using a small control lever
on the left handlebar. It’s a definite
advantage when traversing deep mud, slippery
uphill trails or large logs or rocks.
The front drive shafts of the 750 4x4i
feature Cardan joints. 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 are extremely
rugged and efficient.
New six-spoke cast aluminum wheels replace
the previous pressed steel units and make
a significant styling contribution, while
offering a more premium image and enhanced
credibility on the trail. Mounted with
aggressive tires, the premium wheels help
give the Brute Force its 9.4 inches of
ground clearance and transfer the awesome
power of the V-twin engine to the ground.
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. The sealed rear
brake and dual front discs bring the Brute
Force 750 4x4i to a quick halt. Enhancing
the highly effective braking is the Kawasaki
Engine Brake Control, which helps slow
the ATV when going downhill.
The 2012 Brute Force 750 4x4i features
a new stronger double-cradle tubular steel
frame featuring reinforcements at key
areas like the front A-arm mounts, rear
stabilizer mounts, engine mounts, footrest
mounts, etc., resulting in improved rough
terrain handling and enhanced durability.
The frame’s improved ability to
absorb shocks when sport riding on rough
terrain boosts ride comfort and makes
it easier to maintain a higher average
speed in a wider range of conditions.
A new double-wishbone front suspension
layout features shock absorbers mounted
at a more splayed angle between the upper
and lower wishbones to help minimize sag
and allow a higher ground clearance to
be maintained once a rider sits on the
ATV. The front suspension works in concert
with its independent A-arm rear suspension.
The front wishbones feature adjustable
shocks with 6.7 inches of travel, while
the IRS employs a leading torsion bar
and provides 7.5 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.
New single-rate springs replace the dual
rate units in the front and rear suspension.
The use of single rate springs is preferable
due to the revised suspension geometry
on the Brute Force 750 4x4i. Complementing
the suspension, the urethane seat foam
is supportive yet comfortable for long
hours in the saddle.
An upright and comfortable riding position
enhances the rider’s ability to
interact with the Brute Force 750 4x4i
and allows the rider to effectively scan
the horizon or check the easy to read
automotive-style instrument panel. Its
front bumper is designed to offer effective
hand holds for manhandling the Brute Force
when the need arises. Behind the bumper
is a new set of bodywork molded from tough
and scratch-resistant Thermoplastic Olefin
(TPO). The hood, fenders, bumper and headlight
surrounds were all re-designed to offer
a wide and rugged appearance. Other new
design touches include dual wide-set 35-watt
headlights which help provide excellent
lighting for nighttime rides, and a new
ultra-convenient covered hood storage
compartment large enough to hold two 16
oz. bottles. New cargo racks featuring
stronger tubing that is over 25% larger
in diameter than previous versions and
the addition of tie-down hook points on
the cargo racks make it easier –and
far more reliable– to secure a load.
The cargo racks can carry a combined total
of 264 pounds, making them more than ready
to accommodate the rider’s supplies,
tools and/or outdoor gear.
Underneath this strong bodywork is a
factory-installed plastic conduit for
easy winch installation. A large five-gallon
fuel tank is located beneath the seat
to help keep the center of gravity as
low as possible. Helping to keep weight
in check, aluminum footpegs are surrounded
by tough full-sized composite floorboards.
The capable Brute Force 750 4x4i can
also tow a hefty 1,250 pounds —
all it needs is a standard hitch ball.
Other features include the waterproof
storage box in the left front fender and
a storage pocket in the right front fender.
Owners can expand the versatility of the
Brute Force with a variety of Authentic
Kawasaki Accessories available through
Kawasaki dealers
