Sprockets for the 2003 Yamaha YZ85. 3 sprockets on this page name the 2003 model year outright, by fitment rule or on the listing; the rest fit the YZ85 across its years. The YZ125 through YZ450F and the WRs all run a 520 chain, so a 520 rear listed for the YZ hub fits across the range for its years. The YZ85 runs a 428 and the YZ65 a 420.

The YZ85 runs a 428 and the YZ65 a 420. If a listing names a year range that stops short of 2003, check with us before you order; we answer the same day.
Often, but not always: a new generation changes the part. The YZ125 through YZ450F and the WRs all run a 520 chain, so a 520 rear listed for the YZ hub fits across the range for its years.
