The Kawasaki KX250 underwent a ground-up redesign for the 2025 model year. It arrived with a new frame, a center-port exhaust, a redesigned airbox, and switchable maps highlighting the updates. In 2026, the bike remains unchanged except for new graphics. The ’25 put on a few pounds, however, and finished a disappointing seventh in our eight-bike 2025 250 shootout but was still considered a strong contender in its class.
Not only did we recently ride the 2026 KX250, but we also tested a “customer modified” version provided by Kawasaki’s racing partner, Pro Circuit.
Some highlights of the KX250 include dual injectors, a coned-disc spring hydraulic clutch, an electric start, and a close-ratio five-speed transmission. Electronics are controlled through two selectable power modes, Kawasaki’s Traction Control (KTRC), and a unique launch control mode, which disengages when you reach third gear.
Showa takes care of the suspension, while Dunlop takes care of traction. Kawasaki also redesigned the bodywork with fewer bolts and seams.
As expected, the 2026 KX250 feels just like the 2025. Power delivery is smooth and user-friendly, with impressive low-end. The KX250 already complies with the looming sound restriction, and you can tell. There is a slight “choked up” feel, and it isn’t as “revvy” as previous KX250s.
After a complete overhaul in 2025, the Kawasaki KX250 comes back in 2026 unchanged except for graphics.
However, in the more aggressive engine mode, via the handlebar switch, things liven up from mid to top. You have two engine modes to choose from: normal and aggressive. You’ll like the aggressive mode best; we did. You can take it a step further using Kawasaki’s Rideology KX app. You also have two levels of traction control—weak or strong—to experiment with.
Overall, the latest-generation KX250 is more user-friendly than the previous high-revving screamer generations, and the smoother engine character allows you to ride it hard while feeling in control.
Both the KX250 and KX450 share the same frame, and this platform helps the bike’s stability at high speed, just like the KX450. Weighing 240 pounds wet, the KX is one of the heaviest 250s in its class, but the little extra weight and chassis updates improve grip. Just like the 450, the KX250 always feels firmly planted, especially in the corners.
The KX250’s engine is powerful yet user-friendly.
The forks are a bit harsh right out of the box, and going two clicks softer helped me gain comfort and added traction from the front end. I turned the rear shock’s high-speed damping in one-quarter turn as well, which helped keep the rear end from squatting too much and improved traction on the front tire in twisty sections.
The 250’s Nissin front brake isn’t as good as the Brembo on the KX450, but we’re thankful the front-brake and clutch levers have the same bend now. The Kawi’s cockpit includes Ergo Fit adjustable handlebar mounts and footpegs, along with ODI Lock On grips. The KX will fit a wider range of sizes than any other bike in the class.
The Kawasaki scores points for its easy-to-ride design. It may not be the most exciting in any category, but riders of all skill levels can find a comfortable balance with it. Less-experienced riders will appreciate the smooth power delivery, while experienced racers will value the engine’s tunability and overall rideability while ridden hard.CN
UNCORKED: KX250 Pro Circuit Build
If you want to get more out of the KX250, Pro Circuit, which managed Kawasaki’s 250cc SuperMotocross race team, offers a customer performance package you’ll be interested in. They probably know more about improving the KX250 than anyone. We got to try it.
For those seeking more from the KX250, Pro Circuit offers an easy-to-install performance package that it claims delivers the best value for your money.
The build includes a high-compression piston, a TwinAir Power Flow kit (which features a vented side panel), a full Ti-6 exhaust system, and a rear-suspension link. They also recalibrate the bike’s ECU to work with the engine updates. PC claims this is their best bang-for-the-buck bolt-on system for the late-generation KX250 that doesn’t require open-heart surgery.
The PC engine mods include a high-compression piston, improved airflow, and a full titanium exhaust system.
On track, the modified bike is everything I wanted from the stock KX—more snap and more overall power. It’s amazing what better airflow in and out of the engine can do. Everything from the initial roll-on to the mid-range pull, all the way through to the red line, was noticeably improved or increased. More pull, more rev, more fun. The PC-modified engine is freer revving, which, in turn, makes the chassis feel less bound up. Pair that with the longer link in the rear, and the handling down the hills seemed more predictable and less pitchy.
For 2025 and 2026 Kawasaki KX250 riders looking to upgrade, we can vouch that PC’s performance package can elevate the stock KX to the next level.
