2022 YZ450FX - Pros & Cons

Strengths

Fuel injection: The fuel injection injection system delivers crisp throttle response and reliable cold starts regardless of altitude or temperature.

Considerations

Tall seat height: The 955 mm seat height will challenge shorter riders - tiptoeing at low speeds is something to factor into your decision.

Owner Experiences & Common Issues

Throttle response and fuelling

The fuel injection on the 2022 Yamaha YZ450FX is generally well-regarded. Some owners note a slight hesitation at small throttle openings when cold, which clears once the engine reaches operating temperature. A quick visual check of the injector connectors during routine servicing is good practice on higher-mileage examples.

Valve clearance checks

Double Overhead Cams/Twin Cam (DOHC) engines should have valve clearances checked at the manufacturer's specified interval. Owners report that clearances can tighten over time on higher-mileage bikes, leading to slight ticking from the top end. Catching it early keeps the job simple and avoids more costly remediation.

YZ450FX - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2022 Yamaha YZ450FX, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained YZ450FX should fire up cleanly and settle to a smooth idle within a few seconds.

Oil and filter changes

Regular oil changes are the single most important maintenance task on any YZ450FX. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.

Fuel system care

The YZ450FX's fuel injection system is durable but benefits from quality fuel and the occasional use of a fuel-system cleaner additive. If the bike has been stored for more than three months, drain and replace the fuel to prevent varnish deposits in the injectors.

Valve clearance service

Check that valve clearances have been adjusted at the correct intervals on any used YZ450FX. This is a job many owners skip because the bike does not immediately feel wrong - but tight clearances accelerate valve seat wear. Ask for proof it has been done.
