The next step in that progression is the new 2025 KX250, which receives upgrades in a number of key areas for better racetrack performance while equipping it for its factory KRT MX2 Championship debut in the coming season.
 
In terms of the radically updated spec, the engine power feeling at low speeds and throttle control when exiting corners are both improved for 2025 as a result of a symmetrically aligned intake and exhaust and optimised downdraft intake.
 
Already known for being a nimble, well-handling machine, the KX250 (and cross country KX250X) are now even more agile with updates to the frame and suspension, many of which are similar to those that the KX250’s older sibling, the flagship KX450, received for 2024. These updates - combined with new features such as ODI Lock-On grips and smoother new bodywork - allow the rider to move around on the bike more easily and are destined to translate into faster lap times.
 
Racers will be delighted with the new tech features, including Power Modes and Kawasaki Traction Control, which are easily selectable from a new switch box located on the left handlebar. Additionally, smartphone connectivity allows riders to connect with their machine to adjust engine mapping directly from their smartphones using Kawasaki’s unique Rideology App tuned specifically for the KX.
 
Of course, an “attention getter” is the new engine configuration. Finger-follower valve actuation stays, as does a downdraft-style intake, and dual injectors but these are now joined by a new design of piston plus a revised intake and exhaust layout (with the silencer moved further forward for better mass centralisation) and a single-shaft primary balancer for an all-around stronger package with enhanced control and greater low to mid-range urge.
 
The symmetrically aligned intake and exhaust deliver a strong over-run and smooth low-rpm torque characteristics.  A redesigned intake offers a much straighter route for air-fuel mix to enter the cylinder, while a centrally positioned exhaust port lines up with the intake for high airflow efficiency; both contributing to increased performance.  The optimised downdraft intake also adds to low-end performance while a single-shaft primary engine balancer contributes to smoother power delivery and reduced vibration.
 
There is even a completely redesigned airbox to maximise the potential of the KX250’s dual injectors and match the new downdraft intake.  Complementing the significantly increased low-end torque and the smoother power delivery, throttle response is more linear.
In terms of gear changing, a hydraulic clutch offers more direct feel and lighter lever action plus less play as the clutch heats up during heavy use. The single-shaft primary engine balancer contributes to the smooth power delivery and reduced vibration, which improves throttle control, especially when exiting slower-speed corners.
 
Chassis-wise, the KX250’s new frame is based on that of the 2024 KX450, and updates for 2025 to suit the new intake and exhaust layout help to deliver improved handling.  The smooth bodywork is designed to facilitate rider movement and control plus fine-tuned suspension and brake components further contribute to the KX250’s light, agile handling thanks to its optimised rigidity balance.
 
High-performance Showa ø48 mm inverted coil-spring forks and New Uni Trak rear suspension offer race-ready suspension performance while the Ergo-fit choice of four handlebar positions and two footpeg positions allows riders to tailor their riding position to suit body size and ergonomic preference.
 
The cross-country KX250X benefits from the same swathe of updates for the 2025 season. In addition, cross-country-specific tuning for the suspension, matched to a 21”/18” wheel combination fitted with enduro-type tyres and convenient standard features like a side stand make the new KX250X even more attractive for cross-country competitors.
 
Motocross or cross-country, Kawasaki is as focused as ever to create and provide the most rider friendly, race winning package possible. It was a tough call to make the best better but we are confident that the 2025 KX250 moves the class to the next level allowing aspiring and time served riders the unique ability to fulfil their ambition to “Be Next”.
