Up for sale is a used OEM engine cylinder head for a 2019-2022 KTM 450 SX-F or XC-F as well as a 2019-2022 Husqvarna FC 450 4 stroke dirt bike. This came off a healthy 2021 450 SX-F with roughly 50 original hours. This head was removed by the previous owner to convert a 450 to a 500. An engine builder informed him that the valve guides were a little worn and could stand to be replaced. The buyer should inspect and make their own determination. Everything is original and OEM. There are some scuffs and scratches on the exterior. No cracks, repairs, or damage. Look closely at the pictures. What you see is what you get!
