This is a Honda CRF300L & Rally stock chain. It is the OEM item in Honda packaging, though they are made for Honda by DID and it's a 520VF chain. The Honda part name and number is:
DID 520VF-120ZB (H) 40540-KYJ-902
I also stock the standard 40T rear sprocket and 14T front sprocket if you are looking to replace all together.
