YZ250 Parts Source
These are the additional items you will need to source on your own, that we will not provide.
OEM Honda rear brake caliper:
You can get these OEM from any local Honda dealership, or Rocky Mountain atv, or motosport.com. OR i have some customers get the cheaper Chinese ones off eBay, which also work just fine!
Here is the OEM part number is you want the OEM one

If you want the eBay Chinese one
OEM Style Aftermarket Chinese Rear Hubs:
The rear hubs are Honda pattern, so from a TRX450R. You can get those right on eBay for a cheap pair, just search “trx450r rear hubs” and many listings will pop up. We have even seen them on amazon as well.
OR, I have had some customers get the extended billet ones on Rocky Mountain ATV, which you can also do.

The rear fenders are pretty easy to get. If you want to get OEM Yamaha, you can still get them from any place that offers OEM parts or any dealership, as well as Rocky Mountain ATV.
