The holeshot advantage: Launch Control Mode

The holeshot advantage: Launch Control Mode

The 2015 KX450F features a launch control system similar to that on our factory racers. 

Factory-inspired engine tuning

Factory-inspired engine tuning

Work-base bridged-box bottom piston (unique Kawasaki feature used for the first time on a mass-production motocrosser on the 2010 KX450F) is just one of many features inspired by our factory racers. New piston crown increases compression ratio and improves combustion efficinecy for stronger pull and quicker revving.

Easy engine tuning: DFI Setting Data Selection (3 map choices)

Easy engine tuning: DFI Setting Data Selection (3 map choices)

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.

Race-ready front suspension

Race-ready front suspension

Super-hard titanium coating protects the fork from wear abrasion. Self-lubricating alumite coating creates a hard, low-friction surface on the outer tube, protecting the aluminium surface and further reducing friction to promote smooth fork action.

Slim racer-friendly rider interface

Slim racer-friendly rider interface

The KX450F’s frame and minimalist bodywork, designed with rider ergonomics in mind, offer a slim rider interface and racer-friendly ergonomics. Complemented by adjustable handle and footpeg positions, the natural riding position makes it even easier for racers to go fast.

Adjustable handlebar position

Adjustable handlebar position

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.

Precision engine tuning: KX FI Calibration Kit (option)

Precision engine tuning: KX FI Calibration Kit (option)

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.

SFF-Air TAC (Triple Air Chamber)

SFF-Air TAC (Triple Air Chamber)

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 position

Adjustable footpeg position

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.

Hard-hitting fuel-injected power

Hard-hitting fuel-injected power

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.

Petal brake discs

Petal brake discs

New-design factory-style front and rear petal brake discs offer strong braking performance, excellent control and high-quality sporty looks. Oversized semi-floating 270mm front disc further enhances controllability.

New Uni-Trak rear suspension
