Does anyone know if the 08 YZ450F will fit on the 08 WR450f? I'm at my wits end here and losing patience. :excuseme:

Part #'s don't match, I don't think they swap. :excuseme:

The part numbers wont match...the wr has smog holes casted into it and the yz doesnt...so like i said, it should bolt right up:thumbsup:

I'm with BSD on this one. The YZ will not have the smog ports if that's important to you but other than that it will fit. Part numbers will almost never match even if they are the same part. Yamaha uses a different codes for YZ's and WR's and even different years in the same model.

Who the heck is BSD???

Typo. Should have been BCD cause I'm too lazy to type out your full screen name. My mind knows what I want but my fingers just don't seem to push the right keys! Sorry about that.
