The 2023 Kawasaki KX250 motocross racer features a wide range of updates, just in time for the 2022 AMA Motocross National Championship series. There are chassis and engine changes, which means there are plenty to say. So, let’s take a closer look first.
- Kawasaki focused on the intake and exhaust systems for the 2023 KX250 DOHC engine. The intake tract has been straightened and one of the two injectors has been moved higher up the intake tract. The air/fuel mixture is sent through new 1mm narrower intake valves with a revised pitch 1.5mm narrower than last year. Additionally, the piston head is reworked to be compatible with the new intake valve layout. Once the fuel is burnt—the ignition timing is advanced from last year—the depleted charge comes out of a new 100mm-longer header bike. The result is a claimed increase in horsepower at the upper end of the rev range.
- First gear and second gear are taller on the 2023 KX250. This tightens the gearbox ratio for better acceleration.
- Reliability is addressed by a new big end bearing crush height. Kawasaki upped it.
- The KYB suspension has been refined to improve corner entry and exit. The fork has new settings and a new oil height to give the rider better feel for the front end and deliver a planted feel. For quicker acceleration out of corners, the shock gets firmer compression damping. As always, KYB units have fully adjustable damping and spring preload. Additionally, the new settings increase seat height and ground clearance by 0.4 inches.
- To handle the increased horsepower and new suspension settings, the KX250 has a wider rear tire. The dunlop The Geomax MX33 at the rear is now 110mm wide – down to 10mm – while the front is unchanged.
- Aluminum helps save weight on the 2023 Kawasaki KX250. The fork cover mounting bolts, rear link clamp and footpeg mounts were changed from steel to aluminum. Additionally, the solid bolts in the shock absorber link collar have been replaced with hollow ties. With the larger rear tire, the ’23’s finished weight is just over a pound heavier than last year.
- The KX250 gets new, wider, repositioned footpegs. The new pegs measure 5mm front to back and are moved 3mm rearward.
- The 2023 Kawasaki KX250 gets a $100 price increase. That’s not bad, considering the updates and the rate of inflation. You have the choice between a color: lime green. If you go to your Kawasaki dealer, you can probably check one out in person.
