The 2027 YZ450FX adopts the updated design of the YZ450F, with a philosophical change to its base function that focuses on improving comfort and controllability in technical terrain.
Power character is focused on smoother delivery with more controllable low-RPM torque, making it easier to ride in technical conditions. The suspension characteristics have been specifically optimised to cater to the longer rides of competitive cross-country racing, providing more initial movement, comfort and compliance over slippery, rocky, and root filled terrain.
Overall, the new YZ450FX is easier to ride faster, longer, especially on extremely technical trails.
