2022 Yamaha YZ450FX Overview
The 2022 Yamaha YZ450FX is an enduro / off-road motorcycle built around 449.7 cc of displacement. Under the tank sits a Single cylinder, four-stroke engine running Double Overhead Cams/Twin Cam (DOHC) valve actuation, a compression ratio of 12.8:1. The bore and stroke measures 97 x 60.9 mm. From a practical standpoint, the 2022 YZ450FX tips the scales at 115.2 kg, carries a 8.33-litre fuel tank, offers a seat height of 955 mm and spans a 1481 mm wheelbase. That's roughly 83.6 kg lighter than the average enduro / off-road motorcycle in our database.

2022 YZ450FX - Pros & Cons
Strengths
-
🔧
Fuel injection: The fuel 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.
-
⛽
Modest fuel capacity: The 8.33-litre tank means more frequent fuel stops on longer rides, which is worth planning around on touring routes.
-
⚙️
Chain final drive upkeep: Chain final drive needs regular cleaning, lubrication and tension checks to get full life out of the sprockets.
Wear Points & Servicing Notes
Fuelling & injector care
Fuelling comes from fuel injection. Systems like this are largely maintenance-free beyond keeping fuel quality decent and injectors clear - a fuel-system cleaner every service interval is cheap insurance.
Valve clearance checks
Double Overhead Cams/Twin Cam (DOHC) valve actuation on the YZ450FX means clearances should be checked at the manufacturer's specified interval - they can tighten as mileage accumulates, and a light top-end tick is usually the first sign.
Brake disc and pad wear
The Single disc. Hydraulic front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.
Suspension condition on used examples
Up front, the YZ450FX runs KYB® spring-type fork with speed sensitive damping; fully adjustable and KYB® single shock; full adjustable at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.
Final drive maintenance
Final drive is by chain - expect to clean and lube it every few hundred kilometres and check tension regularly; a neglected chain wears the sprockets faster than the chain itself.
Frame & chassis check
The frame is Aluminum Bilateral Beam frame - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.
Low-speed handling
At just 115.2 kg, the YZ450FX is light enough to manhandle easily at a standstill - one of the practical advantages of its class.
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. A bike with clearances out of spec doesn't always feel obviously wrong - but tight clearances accelerate valve seat wear. Ask for service documentation proving it's been done.
