2014 Kawasaki KFX450R

Posted on by  

The 2014 version of the race ready Kawasaki KFX450R retains the aggressive character of its predecessors providing tons of thrilling off-road fun.

The 2014 Kawasaki KFX450R was carefully designed to deliver top-notch control and precise handling worthy of any off road beast. The aluminum frame helps you remain in total control and allows the suspension to be easily tuned according to the terrain conditions. Talking about suspensions, they include dual-rate front springs and an adjustable rear shock which are able to soak most of the bumps without breaking a sweat.

In its off road adventures, the Kawasaki KFX450R is also helped by a potent, liquid cooled, four-stroke, DOHC, four valve single engine with a displacement of 449 cc. The engine is fueled by a 2.6 gallons fuel tank and it’s power is kept under control by a five-speed transmission with reverse.

Race-Ready Sport ATV Better than a Bird or a Plane

Whether tackling the tallest sand dune or taking the podium on any Sunday, riders turn to the KFX®450R as the sport ATV to take them to the top. An agile chassis and extended A-arm front suspension get off the ground thanks to a race-dominating engine with Digital Fuel Injection (DFI®). Honoring Kawasaki’s aerospace heritage, the KFX450R’s rigid aluminum frame and lightweight components allow it to fly through the air with ease. From one pinnacle to the next, the deep roots of this sport ATV help riders reach their peak.

With a potent powerplant proven on the Supercross championship-winning KX™450F, the KFX450R ATV is ready to race. A strong, tapered, Renthal® Fatbar allows for excellent leverage and nimble handling. On that bar is the magic button... connected to a compact electric starter.

At its core, a highly responsive 32-bit DFI system automatically compensates for temperature and altitude, resulting in mind-blowing thrust conversion from the KFX’s four-stroke engine. Riders can rocket out of corners due to the huge amounts of torque in both the low- and medium-rpm ranges.

The KFX450R’s five-speed manual transmission includes an unobtrusive reverse gear system. Thanks to the KFX’s lightweight aluminum frame, total unit weight is no more than a steel frame without reverse. The convenience of the reverse gear is evident to riders who can quickly and easily extricate themselves from first turn chaos, trail bottlenecks or any other on-track incident, using the normal shift lever plus a convenient handlebar mounted lock-out lever.

2014 Kawasaki KFX450R Key Features:

Kawasaki KFX450R

• 449cc DOHC engine provides a broad torque curve and optimized power delivery for quick acceleration without excessive wheelspin

• Digital fuel injection promotes crisp engine response

• Lightweight reverse gear system is easy to use, perfect for getting out of tight situations

• Electric starting facilitates quicker stall recovery and lowers rider fatigue

• The aluminum frame’s rigidity enhances stability in corners and allows the suspension to be easily tuned to suit course conditions

• Dual-rate front springs and adjustable rear shock provide excellent rough-terrain handling

• Hydraulic disc brakes offer strong, consistent stopping performance

2014 Kawasaki KFX450R Features and Benefits:

Kawasaki KFX450R

449cc liquid-cooled, DOHC, four-valve, four-stroke single

• 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

• 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)

Kawasaki KFX450R

• 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 reduces rider fatigue

5-speed transmission

Kawasaki KFX450R

• Five-speed manual transmission locates reverse below first gear

• Actuating the reverse-lock release lever when in first gear allows rider to easily 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

Aluminum chassis

Kawasaki KFX450R

• 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 weight transfer

• Mounting the battery and coolant tank ahead of the engine lowers the center of gravity and helps weight the front wheels for optimum overall balance and 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

Kawasaki KFX450R

• 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 brake

• 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 brake lever also prevents the clutch lever from being actuated

Water resistant wiring harness

Kawasaki KFX450R

• Resin-molded lead branch points

• PVC cover over the connectors for regulator and TPS

• Fully-shielded tail light lead wires

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

• Reinforced mounting on rear side of fuel tank

• 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 (GNCC) races where light weight is a priority
