Yamaha has announced its 2027 YZ450F and YZ450FX, with the YZ450F returning mostly unchanged and the YZ450FX receiving the bigger update for the new model year. The YZ450F remains Yamaha’s premier 450 motocross machine, while the YZ450FX takes that same platform and adapts it for cross-country racing with a stronger focus on comfort, controllability, and long-ride performance in technical terrain.

The 2027 Yamaha YZ450F is unchanged mechanically for the new model year and only receives updated graphics. Yamaha’s 450 motocross platform remains the same for 2027, continuing with the same engine, chassis and suspension package as the previous model. The 2027 YZ450F will be available from dealers this July in Team Yamaha Blue for $10,299 MSRP.

YAMAHA YZ450FX

The 2027 Yamaha YZ450FX is the big news in Yamaha’s 450 lineup. It adopts the updated design of the YZ450F, but with a change in direction focused on improving comfort and controllability in technical off-road conditions. Updates to the engine, frame, suspension and additional components are aimed at creating a better balance between high-performance 450 power and all-day rideability for cross-country racing.

The new YZ450FX engine is optimized for smoother power delivery with more usable low-to-mid-range torque, making it easier to ride in tight woods, rocky trails, and technical sections. It also receives a new 51-tooth sprocket, a new hydraulic clutch with a 15-percent lighter lever pull, YZ450F-derived frame updates, revised engine brackets, KYB suspension tuned for more comfort and compliance, and Dunlop Geomax AT82 cross-country tires. Overall, Yamaha designed the new YZ450FX to be easier to ride faster, longer, especially on demanding technical trails. The 2027 YZ450FX will be available this September in Team Yamaha Blue for $10,499 MSRP.
