Engine character has been tuned with a focus on low to mid-range power to suit off-road riding. A revised intake port design produces a more linear delivery that enhances machine control. Cam timing changes have resulted in more stable combustion while increased AC magneto inertia promotes a confidence-inspiring delivery aimed at technical and low-speed riding situations. Both changes also increase stall resistance at low speeds. To further improve power delivery, especially when riding flowing third gear trails, the rear drive sprocket has increased in size by one tooth from 50 to 51.
A new frame design for 2027 balances rigidity and flex characteristics. A revised front downtube results in a highly stable ride with enhanced front end feel for improved cornering performance. The new frame is matched with a new high-performance KYB® rear shock and revised fork settings with more progressive settings to provide better front end contact, feel and control to give the rider confidence to charge harder and corner faster.
The updated shock features a new piston that improves damping force in the lowest speed range and expands the range of damping adjustments. The shock also has a new hand-operated low-speed compression clicker for simplified trackside adjustments.
These chassis and suspension updates result in greater usability in everything from slow, tight corners to high-speed sweepers. With better comfort and front end control in technical conditions, the new WR450F is easier to tip in, easier to choose and hold a line and has a higher level of cornering performance.
A new hydraulic clutch provides smooth, consistent engagement with less effort while eliminating the need for on-track adjustments. In addition, a new clutch inner hub design is lubricated over a larger area for stable performance and durability.
New lightweight rear braking components have been reduced in size, including the brake disc, master cylinder and piston diameters. This improves rear brake controllability and saves 180g in total.
Updated styling for 2027 includes a sharper rear fender and new WRF graphics. There is also a new honeycomb-pattern seat cover material that makes sliding forward while braking easier and helps prevent sliding rearward during acceleration.
This model is equipped with Yamaha’s industry-leading smartphone Power Tuner App that features intuitive Quick Setting slide bar engine tuning, Traction and Launch Control, an ECU-lock function and more.
Our mission was to create an intuitive, rider-friendly machine with an exceptional balance of power and handling. An enduro bike with more connection and control for longer, faster and more comfortable fun, as well as effortless slow speed riding.
Developed with input from both Australian and New Zealand riders – including from the successful ShopYamaha Enduro team that dominated the 2026 Australian Enduro titles – the 2027 WR450F features improved levels of control that inspire greater rider confidence.
