KFX450R Monster Energy |
For riders wanting something different in a
race-ready, high performance ATV, the Kawasaki
KFX®450R Monster Energy Edition is the answer.
With its black bodywork, frame and wheels
highlighted by an aggressive Monster Energy®
graphics set, this born-to-race ATV will
certainly stand out from the pack.
The KFX450R uses a powerplant based on
Kawasaki’s highly acclaimed KX™450F motocross
engine. An efficient and highly-responsive
32-bit digital fuel injection (DFI) system
automatically compensates for temperature or
altitude. DFI also enhances the engine’s ability
to generate torque in the low and medium rpm
ranges for outstanding holeshot acceleration.
This ATV’s ability to find traction is superb,
and its four-stroke power delivery translates
into hooked-up wheels for improved handling and
higher corner speeds.
Other race-ready features include a
lightweight titanium exhaust header pipe and a
durable forged piston. The fast and reliable
KFX450R was also the first competition-oriented
ATV to include a reverse gear. Previously
unheard of in racing, the KFX450R’s lightweight
reverse system lets riders quickly extricate
themselves from first turn chaos, dead-end
trails or any other on-track incident.
Winning races requires a chassis that’s built to
handle tough racing conditions. The all-aluminium
frame provides light weight and incredible
stiffness without sacrificing strength. The
front suspension design utilizes long lower
A-arms mounted to a single box-section lower
frame tube. This results in outstanding
suspension action from the frontend. At the
rear, a cast aluminium swingarm provides the
ideal balance of flexibility and rigidity. The
high-tech chassis also features a low center of
gravity and excellent roll resistance.
Regardless of changing conditions or rough track
surfaces, this race-oriented chassis makes the
KFX450R a potent weapon in the battle for ATV
supremacy.
The KFX450R is easy to work on, so riders can
concentrate on winning instead of wrenching. The
two-piece front and rear “lapped” fenders make
it possible to customize the size of the fenders
or replace damaged sections separately. Even the
headlight assembly is quickly detachable for
closed-course races, and the compact design
means this ATV looks just as aggressive with or
without headlights. These features leave little
doubt that the new KFX450R was designed to get
its rider on track and winning races as quickly
as possible.
The KFX450R was developed concurrently with a
full line of Authentic Kawasaki Accessories that
are available through Kawasaki dealers.
Features
449cc liquid-cooled, DOHC, four-valve,
four-stroke single
- A lightweight forged piston reduces
reciprocating weight
- Triple piston rings and a 21mm diameter piston
pin help increase durability and reduce
necessary maintenance
- Lightweight titanium valves and aluminum valve
spring retainers reduce reciprocating weight and
boost high-rpm reliability
- Asymmetrical high-acceleration cams yield high
intake efficiency
- Lightweight high-performance titanium exhaust
header contributes to low and mid-range throttle
response
- Electric starting facilitates quicker stall
recovery and lowers rider fatigue
- Large-volume airbox contributes to both intake
efficiency and sharp engine response. An air
duct fashioned from polyethylene resists
deformation caused by intake pulses and helps
ensure stable engine performance
- Advanced engine tuning provides a broad torque
curve and an optimized power delivery for quick
acceleration without excessive wheelspin
Digital Fuel Injection (DFI)
- 32-bit digital fuel injection system with a
42mm throttle body
- System measures coolant temperature, air
intake temperature, air intake pressure, engine
speed and throttle position, then automatically
delivers the ideal amount of fuel to optimize
power delivery
- Crisp engine response is especially
advantageous for instant acceleration after
landing from jumps
- Promotes trouble-free starting –a great
benefit in races with engine off starts
- Fuel injection allows the use of a lighter
throttle return spring, which reduce rider
fatigue
Transmission
- The five-speed (one-down, four-up) manual
transmission locates the reverse gear below
first
- Actuating the reverse-lock release lever when
in first gear allows you to shift “down” into
reverse
- Compact reverse-lock release lever can be
activated with the right thumb, allowing the
reverse gear to be engaged while still keeping
the front brake lever depressed
- The combined weight of the reverse gear system
and the lightweight aluminum chassis is no
heavier than using a steel frame without reverse
Aluminum Chassis
- Highly rigid frame contributes to the KFX’s
excellent handling and traction
- The aluminum frame’s high torsional rigidity
enhances stability in corners and allows the
suspension to be easily set up to suit course
conditions
- Designed for high corner speeds, the KFX450R
sits low to the ground, helping to reduce roll
tendencies
- Mounting the battery and coolant tank ahead of
the engine lowers the center of gravity, and
helps weight the front wheels for increased
traction
- Single box-tube lower frame contains the front
A-arm attachment points. This narrower design
enables the use of longer lower A-arms
Advanced Suspension Design
- Dual-rate front springs deliver progressive
suspension travel for excellent rough-terrain
handling
- Extra-long lower front A-arms minimize camber
variations through the suspension stroke,
maximize front wheel traction and boost
stability
- Rear shock features both low- and high-speed
compression adjustability and adjustable rebound
damping
- The curved lines and rounded edges of the cast
aluminum rear swingarm help disperse stress,
which along with its varied wall thicknesses
equal a design that is both light and strong
- The swingarm’s high torsional rigidity
contributes to excellent rear wheel traction
- The rear axle is tapered for less unsprung
weight
Front and Rear Disc Brakes
- Dual front hydraulic disc brakes offer strong,
consistent stopping performance
- Petal-type rear brake rotors reduce unsprung
weight and help clean the brake pads for more
efficient braking performance
- Integrated rear parking brake is designed to
be easily engaged and released while wearing
gloves. When engaged, the parking
Monster Energy Edition
- Special painted black aluminum frame
- Special black wheels
- Molded black Thermo-Plastic Olefin (TPO)
bodywork provides ultra-high gloss appearance
and is scratch-resistant
- Special Kawasaki Monster Energy graphics rake
lever also prevents the clutch lever from being
actuated
Additional Features
- Two-tone seat features a smooth top surface
for excellent rider mobility and slip-resistant
sides for good grip when hanging off in corners
- Seat, tank and side covers are shaped to allow
excellent rider mobility and to provide support
when hanging off in corners.
- Tapered Renthal Fatbar offers both strength
and light weight
- Handlebar mount is designed to accommodate
other MX-type handlebars, enabling riders to
select from numerous after-market styles
- Specially designed rear wheels feature
reinforcing plates for the rims. Located on the
axle side of the rims, these plates reinforce
the rims where strength is most needed while
minimizing weight
- Wide front bumper, can be gripped with two
hands to push/pull the ATV
- Two-piece “lapped” front and rear fenders can
be replaced separately in the event they are
damaged
- Detachable front headlight assembly can easily
be removed for racing
- Optional kick-start system is available for
MX-style (GNC) races where light weight is a
priority
