The 2025 and the 2026 YZ250F are the same exact motorcycles. In 2025 the suspension valving got a little stiffer and also got a different linkage so the rear spring went from 56N/m to 54Nm. After a long time spent on the 2025 YZ250F and some time on the 2026 model, we think we have found a comfortable spot for you all to start from. KYB/Yamaha did a better job in 2025/2026 with getting the fork to stay up higher in the stroke, but to us it’s still a little too quick when loading the front end through corners. We found ourselves washing the front end out because the fork would come up too quickly as we started to settle into the corner (transitioning the throttle on), which made the front feel high in area 2 of corners. Slowing the rebound down in fork as well as the shock made the chassis feel calmer. The rear of the Yamaha still feels high in the rear if you’re on the lighter side (less than 160 pounds), so softening the HSC helps allows the rear to squat a little more on exits of corners. This also helps the fork settle on braking bumps as well. When new, the KYB suspension will feel stiff/harsh but give it a couple hours and it will move more freely then you will understand what we are saying by it being a little too quick.

If you want a little less engine braking feel from your YZ250F and gain some pulling power out of the corner, try this map below. Make sure your TC is off when installing this map. Also make sure the position is set to our spec and not the default spec.
