Detailed: 2024 Kawasaki KX range

All-new KX450 uncovered alongside the returning KX250 model.

The anticipated new 2024 Kawasaki KX450 has been unveiled today, marking the brand’s latest premier class contender and featuring a mixture of all-new features for next season, in addition to the returning KX250.

Those include a new cylinder head, lightweight aluminium frame, centre exhaust, and Kawasaki KX first-time features include ODI Lock-On grips, Brembo brakes, Kawasaki Traction Control (KTRC), riding modes with handlebar-mounted switch box, and connectivity using ‘Rideology The App’.

In terms of the engine, for 2024 Kawasaki changed the layout of the entire intake system, all the way down to the valves which were modified to an ideal port shape and shifted vertically to be symmetrical with the intake and exhaust ports.

Its intake and exhaust ports were also modified for straighter airflow and improved efficiency. As a result, power is improved across all areas at any throttle position or engine RPM.

The exhaust pipe has been moved to the centre of the bike, helping to contribute to both peak power and controllability while allowing for slimmer bodywork. The pipe’s silencer was moved forward as well, contributing to mass centralisation and a firmer feel.

An all-new lightweight aluminium perimeter frame retains the praised handling character of the previous model, with optimised stiffness and dimensions that help improve the front-end feeling and traction while riding in various conditions.

For the first time in KX history, a Brembo braking system will adorn the front of the KX450, including a master cylinder and brake calliper for excellent stopping power controllability. A Nissin braking system will remain on the rear of the motorcycle for a combined braking package that is intended to produce seriously fast lap times.

Improving the overall ergonomics while maintaining the KX machine’s pure racing style was a priority for Kawasaki engineers. The 2024 KX450 will feature all-new bodywork that allows riders to change their riding position more easily.

The shrouds, side covers and rear fender all received updates to their design, condensing the KX450’s overall appearance for a lighter-looking feel while adding to the mass centralisation of the bike itself. A new quick-release design will be featured on the side cover, facilitating convenient, tool-less access to the air-filter.

For added rider comfort, ODI Lock-On grips will come standard on the KX450. This innovative grip system bolts the grips to the handlebar and will simplify the process of replacing grips. The grips will be accented with green details in the rubber tips and mounting hardware, continuing the motorcycle’s sharp racing image.

A new traction control and power mode switch enhance the left handlebar, marking another first for the KX line of motorcycles. Riders will be able to choose their level of KTRC assistance (strong, weak or off), adjust between power modes (normal or mild response) and activate launch control at the push of a button.

Power mode mapping can now be adjusted using ‘Rideology The App’, which is another KX series first. Instead of using the current accessory FI calibration kit, riders will now be able to adjust fuel and ignition timing and keep a maintenance log using Bluetooth connectivity from their smartphone.

Alongside it, the 2024 Kawasaki KX250 will remain unchanged. Tuned for race-experienced riders, the 2024 KX250 is powered by a 249cc liquid-cooled, four-stroke engine that is designed to achieve strong performance across the rev-range and result in quick lap times and excellent holeshot performance.

The KX250 continues to utilise the finger-follower valve actuation – a valve train to help achieve a high rev limit that allows for the use of more aggressive cam profiles and contributes to high rpm performance. Dual injectors complement the powerful engine and increase engine output at high RPM.

A slim aluminium perimeter frame was designed with lightweight, nimble handling, and slim ergonomics in mind. Large-diameter 48mm KYB inverted coil-spring front forks have a Kashima coat on the outer tubes, while on the rear, a KYB shock unit complements the front fork and features dual compression adjustability.

Add in Braking brand rotors, which delivers strong braking force and superb control, Dunlop MX33 tires, a factory-style aluminium Renthal Fatbar handlebar and an adjustable cockpit, all of its favourite features are back for another year.

Sleek bodywork with factory-style graphics help ensure that the KX250 is one of the sharpest-looking bikes in the paddock and further reflects its highly-tuned performance. Further information will be found at
