The 2014 KX450F features a launch control system similar to that on our factory racers. With the simple press of a button, riders can activate a separate engine map designed to ensure efficient race starts in slippery conditions. (the Launch Control Mode map retards ignition timing, allowing tyres to gain grip in low-traction situation, and allowing riders to focus on their lines)

High performance piston (featuring the same design used on our factory racers), ECU settings and wedge-shaped crank web ensure top-level performance right out ofthe box at all rpm.

Using provided DFI couplers, riders are able to easily switch to suit riding conditions. Plugging in each of the 4-pin couplers activates the corresponding engine map. Each of the three maps can be reprogrammed using the optional KX FI Calibration Kit.

A super-hard Diamond-Like Carbon reduces sliding friction (and stiction). The coating is even effective when exposed to lateral forces that would hamper slide action. The surface hardness minimises scratches and damage to the tubes.

The KX450F's slim aluminum perimeter frame is a lightweight construction composed of forged, extruded and cast parts. Slim frame, minimalist bodywork and a flat tank-seat line were designed to make it wasier for racers to go fast. Designed with rider ergonomics in mind offers a slim rider interface and racer-friendly ergonomics. New handle grips with a revised pattern offer increased grip.

Upper triple clamp with two sets of handle mount slots and reversible handle mounts offer riders a choice of four handle positions to choose from: 25 mm FWD, 15 mm FWD, STD and 10 mm BK.

The KX FI Calibration Kit enables expert riders to adjust engine characteristics (by rewriting actual data maps) to suit their preference, record riding data, and analyse their riding data to further fine-tune their settings.

Factory-racer-style SFF-Air TAC front fork locates its damping assembly in the left fork tube and a pneumatic spring, comprised of three pressurised air chambers, in the right. Light weight, low friction, easy adjustability, a wide setting range and precise settings are some of the advantages.

Adjustable footpeg brackets enable riders to lower their footpeg position 5 mm. In the lower position, CofG is lowered as is the rider’s point of view, adding to both physical and psychological stability.

Fuel-injected 449 cm³ liquid-cooled, 4-stroke Single delivers hard-hitting power from low- through high-rpm. The broad powerband and responsive throttle offer a broad spread of torquey response that enables racers to get on the gas and go even from down low.

The KX450F features petal brake discs front and rear. In addition to helping reduce unsprung weight, the wave shapes of the petal discs help clean the brake pads for more efficient braking performance.

Linkage mounts below the swingarm for more precise suspension tuning. Dual compression adjustability offers a wide range of tuning options. Kashima coat on the tank cylinder improves action, additionally extensive rider testing was conducted to determine the ideal linkage ratios and rear shock absorber damping settings to achieve maximum rear wheel traction.

Aluminium perimeter frame is a lightweight construction composed of forged, extruded and cast parts. Slim design contributes to racer-friendly ergonomics.

Complementing the factory-style design and graphic, black alumite rims, black fork guards, blue alumite finish on the suspension adjusters, and a blue finish on some of the engine trim give the KX450F the looks to match its highly tuned performance.
