Description

It's no wonder that Kawasaki's KX™450F has amassed an enviable championship record in AMA Supercross and AMA Motocross. Having a great rider definitely helps, and Monster Energy® Kawasaki's Ryan Villopoto's credentials are impeccable, including double-up titles in AMA Supercross and Motocross titles in 2011, followed by another AMA Supercross title in 2012. And in 2013, Villopoto made it three straight Supercross championships in a row, becoming the first rider to win back-to-back-to-back AMA Supercross titles since the great Ricky Carmichael, another rider whose career blossomed aboard Team Green™ machines.

Engine Overview

• 449cc, liquid-cooled, DOHC, four-stroke single with legendary Kawasaki power!

• Works-based bridged-box bottom piston has optimum rigidity for maximum high-rpm power and durability

• A forward lean angle of 3° puts the engine in the ideal position for maximum traction

• Highly balanced crankshaft, on par with Villopoto’s factory racer, creates minimal vibration and has a high inertial mass to help maximize rear wheel traction

• Compact cylinder head is only 100mm tall

• Double valve springs help ensure stable valve operation and also allow for a short cylinder head height

• Camshafts, lobes and tappet surfaces feature a soft-nitride treatment for long wear and high-rpm reliability

• Automatic cam chain adjuster is maintenance-free

• Crankshaft and connecting rod feature a special carburizing and quenching treatment to maximize rigidity, boosting long-term reliability without adding weight





Digital Fuel Injection

• Digital Fuel Injection (DFI®) self-adjusts to atmospheric changes for easier starting, sharper throttle response and accessible power for jumping

• It is not necessary to re-tune or change any jets to suit climatic conditions like carbureted models

• Ultra-fine atomizing injector with 12 holes sprays particles with a droplet size of 60µ for smooth power delivery and engine response throughout the throttle range

• 43mm throttle body uses a progressive throttle linkage to deliver airflow in much the same way as an FCR carburetor

• Using two linked shafts, the throttle body opens more quickly after reaching the 3/8 open position

• Fast-idle knob on the throttle body allows riders to increase engine speed when starting a cold engine

• Fuel injector set at 45°, the optimum angle for mid-range power





High-performance Multi-map ECU

• Ignition timing boosts response when re-opening the throttle after deceleration (when landing jumps, etc.)

• ECU programming is easily selectable via interchangeable DFI coupler caps that provide three preprogrammed maps for standard, hard (terrain) and soft (terrain), without the need for a separate programmer or laptop

• The engine can be started with only three rotations of the crankshaft using the electricity generated by a single kick of the starter, no battery needed

• The system delivers electricity to the bike’s electronics in sequence: first the ECU, then the fuel pump, and finally the injector for quick, easy starting

• The compact, lightweight ECU, located on the front of the steering head behind the number plate, was designed specifically for motocross use. The fuel pump relay is integrated with the ECU to help cope with the shocks and vibrations of tough racing





Launch Control Mode

• Factory-style launch control system is an industry first and increases the ability to get good starts by maximizing available traction

• Push-button activation of the Launch Control Mode retards ignition timing in first and second gears, giving the greatest effect within the first few seconds of releasing the clutch

• Launch Control can be activated in neutral, first or second gear

• Shifting into third gear automatically deactivates Launch Control Mode and returns the ignition to normal mapping





Easy Starting

• Strong output from the large ACG rotor provides enough electrical power for the battery-less FI system to enable true one-kick starting without using a battery

• Equipped with an automatic compression release (ACR) system for quick and easy starting. The dual-weight centrifugal decompression system is fitted to the exhaust cam

• Compression release features 1.0mm of valve lift, to minimize the required kicking power





Bridged-Box Bottom Piston

• Piston crown shape tuned for excellent low to mid-range engine response

• Same design as used on our factory racers; offers optimum performance at all rpm

• Lighter and more durable than traditional piston designs

• Short piston skirt features low-friction coating to minimize mechanical losses

• Reinforced external ribs enhance strength and durability





PSF Front Fork

• 48mm Kayaba Pneumatic Spring Fork (PSF) uses compressed air as a spring. The reduced weight and inertia of the air spring improves smoothness and enhances the fork’s ability to follow terrain contours

• Air spring significantly reduces friction and cuts weight by 1.7 lbs. per set, while also providing better bottoming resistance, less oil contamination, plus easier and more effective tuning compared to traditional springs

• Large 32mm diameter internal damping cartridges help provide consistent performance and bottoming resistance

• A removable spring pressure adjustment valve and free Kawasaki Genuine PSF Air Fork Pump, are included for quick and easy tuning of fork spring pressure

• Diamond-Like Carbon (DLC) coating on the outer surface of the inner fork tubes offers minimum stiction when the fork is exposed to lateral forces that would usually hamper slide action. The result is improved fork response, especially during cornering

• Friction-reducing Kashima Coat on the inside of the fork’s outer tubes contributes to smooth suspension action (especially at the initial part of the stroke)

• Wrap-around fork tube guards offer effective protection for the sliders

• Lower triple clamp features integrated locating pins to help simplify installation and removal of the front number plate

• One-piece front fender attachment screws feature integrated grommets to simplify installation and removal





Rear Shock

• 33-position rebound damping adjuster allows precise fine-tuning of the rebound circuit

• Easy adjuster access allows track-side suspension tuning with a minimum of hassle or lost time

• Rear shock features dual compression adjustability, allowing 22-position high-speed and stepless low-speed damping adjustments to be made independently

• Kayaba rear shock features a large 50mm piston and a Kashima Coat treatment on the cylinder wall for reduced friction and smoother suspension action





Aluminum Swingarm

• Tapered “D” shape swingarm is lighter than a comparable box-section unit and provides superior rigidity for its weight

• Features tapered hydroformed spars and forged chain adjusters

• Uni-Trak® rear suspension linkage is mounted below the swingarm to allow precise tuning and maximum rear suspension stroke





Fuel Tank and Lightweight Aluminum Fuel Pump

• Compact 1.6-gallon fuel tank is formed using a blow molding process

• Fuel pump features a one-piece filter cover and body, eliminating the need for fuel return tube from pressure regulator

• Features a plastic fuel filter cover that wraps around the inlet port and acts as a fuel trap to help ensure a stable fuel supply during vigorous motocross riding





Efficient Cooling

• High-capacity Denso radiators feature tightly packed cores and a fin design that deliver superior cooling efficiency

• Shroud shape features a slim profile and large cooling outlet hole to help keep excess heat to a minimum

• Radiator louvers feature four small blades set at a shallow angle for minimum overlap and maximum air flow





Strong and Durable Clutch

• Clutch assembly provides a direct feel and superb control of engagement

• Excellent oil drainage reduces power loss caused by excess oil around the clutch basket

• Friction plates with substantial friction material contribute to fade resistance and long service life

• Clutch case cover features embossed logo and is painted silver, making scuffs and normal wear less noticeable





Close-Ratio 5-Speed Transmission

• 5-Speed transmission and the engine’s broad torque curve gives riders more gear options for maximum drive on a wide range of tracks

• Thick first gear offers excellent durability for launching off the line in high-traction situations





Powerful Disc Brakes

• Front master cylinder features a knocker-style lever-to-piston interface for excellent feel and more consistent performance

• Front brake pads offer a strong braking force and feel

• Lightweight 250mm front rotor is squeezed by a powerful twin-piston caliper and features an aggressive petal design to help clear mud and debris

• Lightweight 240mm petal-type rear rotor features the same aggressive petal style as the front rotor and is gripped by a single piston hydraulic rear caliper





Rider Interface and Styling

• Narrower grips are softer and more comfortable for 2014

• Long grips feature a pattern that makes life easier on the rider’s hands

• Slender frame helps the bike feel compact and nimble, but tapers to become wider near the rider’s ankles to offer optimum grip and control

• Wide 50mm footpegs can be adjusted to alternate position, 5mm lower than stock

• Dual injected 2-tone, one-piece plastic shrouds and side number plates are great looking, compact and lightweight

• Black triple clamps and black anodized rims – just like Kawasaki’s factory teams

• Blue finish on suspension adjusters and engine plugs look like the factory race parts

• Slim seat design uses urethane foam designed to retain its original shape and provide optimum durability





Additional Features

• Skid plate made of resin material offers great protection without excess weight

• Clutch cable boot features a large quick adjuster, making it easy for riders to adjust clutch play on the fly

• Rear caliper guard helps protect the caliper from damage

• Ribless rear hub and butted spokes offer light weight and excellent durability





Optional KX Accessories

• KX DFI Calibration Kit allows racers to reprogram the ECU’s data maps for volume of fuel injected and ignition timing to alter engine characteristics to suit rider preference. An ECU setting is available, which can also be used as a data logger, recording up to six hours of data, including engine rpm, degree of throttle opening, engine boost, coolant temp, air temp, ignition timing, fuel adjustments, gear position and system voltage

• Kawasaki recommends a 0-60 PSI air pump with bleeder valve and no-loss Schrader valve connector, Kawasaki part# K5609-060A for adjusting fork air pressure with maximum accuracy and ease of use
