Here is a used head from a running 2020 Honda CRF450R. It has been cleaned and lubed for storage.  Approx 100 hours on head. Bike had a transmission failure, parting out.  Oem part # is 12010-MKE-A70. Verify with your dealer if this will work for you.  No returns, especially if ordering for wrong bike.  Free shipping. 

Comes with cam tower and bolts. All threads are nice and clean.  No "repairs" done to it. 

Thee part # is decoded to a 2019 and 2022 CRF450R / RX

Thanks
