Product description

The KFX®450R is Kawasakis sport ATV flagship! Sitting low to the ground on its adjustable suspension with long front A-arms, the KFX450R employs a lightweight and strong aluminium frame and five-speed transmission with reverse to harness the power from its fuel-injected, electric-start engine. Its impressive power and handling allows riders to maximize their performance on the track or in the woods.

449cc liquid-cooled, DOHC, four-valve, four-stroke singleA 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
TransmissionThe 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 ChassisHighly rigid frame contributes to the KFXs excellent handling and traction
The aluminum frames 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 DesignDual-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 swingarms high torsional rigidity contributes to excellent rear wheel traction
The rear axle is tapered for less unsprung weight
Front and Rear Disc BrakesDual 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 brake lever also prevents the clutch lever from being actuated
Additional FeaturesTwo-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
