2024 Yamaha WR450F

Due January 2024

The 2024 WR450F takes all the latest advancements found on the latest YZ450F and builds upon them to create the ultimate trail-ready enduro machine, with engine and chassis tuning optimized for accessible power, handling balance, and flexibility on every trail.

The all-new engine features larger 39mm-diameter intake valves, a new piston, conrod, big end, revised bearings, optimised crank mass inertia and a dry sump oil tank with integrated generator cover. Many engine components are lighter including the intake ports, piston, cylinder body, crank assembly, cam chain, con rod bearings and lubrication system, which results in an engine that’s 1.1 kg lighter.

In addition, the MY24 WR450F features an ECU tuned specifically to offer tractability at low speeds and high power at medium to fast-speeds. The new model features the same exhaust pipe design as YZ450F - which runs a short muffler for mass centralisation resulting in improved manoeuvrability and appearance.

The extensive weight saving program continues with a lightweight Lithium-Ion battery that replaces the outgoing model’s lead acid unit. A new aluminium footpeg bracket saves 100 g and the stopper’s construction has been changed to prevent mud from clogging up the pegs and from the footpegs biting into the ground on contact. Even the throttle wires are lighter, which contributes to the MY24 WR450F tipping the scales at 117kg* full of fuel which is 2kg less than the previous WR450F.
