2022 Yamaha YZ450F Overview

Yamaha YZ450F is a cross / motocross motorcycle, displacing 449 cc. Power comes from a Single cylinder, four-stroke engine running Double Overhead Cams/Twin Cam (DOHC) valve actuation, a compression ratio of 13.0:1. Bore and stroke come in at 97 x 60.9 mm. On the road, the 2022 YZ450F tips the scales at 111.1 kg, carries a 6.06-litre fuel tank, offers a seat height of 965 mm and spans a 1486 mm wheelbase. That's roughly 12.5 kg heavier than the average cross / motocross motorcycle in our database. The full 2022 Yamaha YZ450F spec sheet below covers every technical detail, from suspension travel to tyre sizes.

2022 YZ450F - Pros & Cons

Strengths

Fuel injection: Fuel injection means consistent cold starts and clean throttle response without the fussiness of a carbureted setup.

Considerations

Tall seat height: At 965 mm, shorter riders will likely be on tiptoes at a standstill - worth sitting on one before you buy.
Modest fuel capacity: Range between stops is limited by the 6.06-litre tank - plan fuel stops accordingly on longer routes.
Chain final drive upkeep: Budget time for routine chain maintenance - it's cheap to replace but needs consistent attention to avoid premature sprocket wear.

Wear Points & Servicing Notes

Fuelling & injector care

The fuel injection on the YZ450F needs little beyond good fuel and periodic use of an injector-cleaner additive - no jetting or float-bowl maintenance to worry about.

Valve clearance checks

With Double Overhead Cams/Twin Cam (DOHC) valve gear, the YZ450F needs periodic clearance checks; caught early they're a cheap adjustment, left unchecked they accelerate valve seat wear.

Brake disc and pad wear

Braking up front comes from Single disc. Hydraulic. - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Suspension condition on used examples

The YZ450F's suspension runs KYB Speed-Sensitive System, inverted fork: fully adjustable at the front. The rear uses KYB® single shock; fully adjustable. Fork-seal condition and rear linkage play are the two things worth checking before buying used.

Final drive maintenance

The YZ450F uses chain final drive, which is cheap to replace but needs regular cleaning, lubrication and tension checks to get a full service life out of the sprockets.

Frame & chassis check

Built around a Bilateral beam frame, aluminum, the YZ450F's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.

Low-speed handling

111.1 kg keeps the YZ450F easy to move around in tight spaces, car parks and on the stand alike.

YZ450F - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2022 Yamaha YZ450F, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy YZ450F should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects a YZ450F's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). The sump holds 1 litres, so budget for that volume of quality motorcycle-specific engine oil. Match the viscosity grade to what the owner's manual specifies, not what's cheapest.

Fuel system care

Fuel injection on the YZ450F needs little attention beyond decent fuel and an occasional system-cleaner additive. Anything left standing for three months or more should have its fuel drained and replaced before it varnishes the injectors.

Valve clearance service

Valve clearances are easy to overlook on a used YZ450F since a bike out of spec doesn't always feel obviously wrong - but the wear it causes is real. Ask the seller for documentation before assuming it's been done.
