Good To Know

Q: Is this an original Yamaha part? A: This is an aftermarket timing cam chain damper that cross-references OEM 6D3-12251-00-00. It is not an original Yamaha product.

Q: Do I need to replace the timing chain at the same time? A: If the chain shows stretch or wear, replacing the damper and chain together is common practice. Confirm condition before ordering.
