For the 2027 model year, Yamaha has updated the WR450F with a revised chassis, new suspension, a new braking setup, and a new visual aesthetic.
What are the major updates for 2027?
For 2027, Yamaha has focused heavily on rideability, stating that the WR450F has undergone significant changes to refine its power and handling so that it can tackle both fast‑flowing trails as well as tight, technical tracks.
What type of engine does the 2027 Yamaha WR450F have?
2027 Yamaha WR450F uses a liquid‑cooled, 4‑stroke, DOHC, 4‑valve, single‑cylinder 450cc four‑stroke engine, derived from Yamaha’s YZ450F motocross platform but tuned specifically for enduro and trail use.
Power is transferred through a 5-speed gearbox. The updated engine gets a revised intake port geometry and cam timing, enabling the engine to produce a more linear torque curve. Yamaha has also increased magneto inertia, aiding in smooth throttle response at crawling speeds and reducing stalling when navigating obstacles and steep climbs.
What type of frame, suspension and brakes does the 2027 WR450F use?
The 2027 Yamaha WR450F is built on a new aluminium bilateral beam frame with WR‑specific engine mounts designed to balance rigidity and flex for improved stability and cornering feedback. Suspension is sourced from KYB, with a fully adjustable Speed Sensitive System fork offering 310 mm of travel at the front and a new high‑performance rear shock with 315 mm of travel.
As for braking, the Yamaha WR450F incorporates a 270 mm front disc with a Nissin calliper and a 220 mm rear disc paired with a lighter master cylinder, smaller piston diameters and new pad material. Yamaha states that these rear brake changes improve controllability and save about 180 g in total unsprung and rotating mass.
