2020 Yamaha YZ450FX Chains

Chains for the 2020 Yamaha YZ450FX. One chain on this page name the 2020 model year outright, by fitment rule or on the listing; the rest fit the YZ450FX across its years. The full size YZ and WR run a 520 chain, the YZ85 a 428 and the YZ65 a 420. Stock lengths run 114 to 118 links on the full size bikes, and a 120 link chain cut to length fits any of them.

Set your bike at the top of the store, with the year, and every list in it narrows to parts with confirmed fitment. Members pay the member price on every product in the store and get free standard shipping on orders over $10. Membership is $5 for the first month.

Questions riders ask

The chains listed first here name the 2020 YZ450FX by year. The full size YZ and WR run a 520 chain, the YZ85 a 428 and the YZ65 a 420. Stock lengths run 114 to 118 links on the full size bikes, and a 120 link chain cut to length fits any of them. If a listing names a year range that stops short of 2020, check with us before you order; we answer the same day.

Stock lengths run 114 to 118 links on the full size bikes, and a 120 link chain cut to length fits any of them. Every listing on MWMX names the years it covers, and the 2020 is in the year range of everything at the top of this page.
