Yamaha WR450F Parts & Accessories

The Yamaha WR450F is a race-bred enduro weapon built on the legendary YZ450F motocross platform. Designed to handle everything from fast trail riding to tight technical terrain, the WR450F is light, powerful, and supremely agile—making it a favorite among off-road riders across Australia. Built to full ADR specifications for registration, it’s just as at home on the road as it is in the bush. Add the supplied Off-Road Kit and you’re ready for full competition mode.

At Top Two Moto, we offer a wide range of Yamaha WR450F parts to keep your ride in peak condition.

Replacing Yamaha WR450F Battery

The Yamaha WR450F relies on a dependable 12V battery for its electric start system—essential for trail and competition riding. If your battery is struggling to hold charge or showing signs of age, it’s time to replace it. At Top Two Moto, we offer a range of Yamaha WR450F battery options including lightweight lithium and maintenance-free AGM models. Upgrade for reliable starts, longer rides, and peace of mind on every track.

Buying Yamaha WR450F Chain & Sprocket

Your WR450F’s drivetrain takes a beating—especially on rocky trails and deep ruts. Swapping out worn chain and sprockets is crucial for maintaining performance and avoiding breakdowns. Our Yamaha WR450F chain & sprocket kits come in various configurations including high-strength steel for durability and lightweight alloy for racing. Get a proper fit, correct gearing, and long-lasting performance from your drivetrain with Top Two Moto.

Changing Yamaha WR450F Motor Oil

Keep your WR450F’s high-compression engine running smoothly with regular oil changes. We recommend quality 10W-40 four-stroke motorcycle oil that meets JASO MA2 standards for wet clutch compatibility. Changing your Yamaha WR450F motor oil and filter after hard riding conditions or every few rides extends engine life and improves throttle response. At Top Two Moto, we stock trusted brands and full oil service kits for easy maintenance.
