450cc High Performance Engine

The new 2025 YZ450FX's advanced four stroke engine has been completely redisgned to be lighter, more compact, higher revving and more powerful across the entire rev range. Among the changes are new exhaust and intake port shapes, larger diameter titanium intake valves, new piston, cylinder, crankshaft and balancer assembly, and a switch from wet sump to dry sump lubrication. Additionally, ECU setting are tailored to suit the specific needs of cross country and enduro competition.

Class Leading Suspension

Settings on the industry-leading, fully adjustable KYB coil-spring type fork with enhanced speed-sensitive damping have been revised to suit the machine and off-road conditions and have the addition of toolless compression clickers for ease of adjustment. The link type rear suspension features a KYB shock with cross country focused damping characteristics to match the YZ450FX's chasis.

Adjustable Engine Mapping

New lightweight handlebar mounted switchgear allows the rider to quickly select between pre-loaded engine maps- loaded and configured in the Power Tuner App- to adjust for changing riding conditions. Map 1 provides more responsive, quicker revving engine characteristics while Map 2 provides smoother response and slower revving characteristics for when traction is limited.

Aluminum bilateral beam frame

Striking the perfect balance of precise cornering performance and handling stability, tje redesigned aluminium frame consists of more than 10 different aluminium components welded together with YZ450FX specific XC-tuned engine mounts. The result is a better handling machine with lighter feel, improved bump absorption and increased traction.
