Genuine DID Motorcycle Drive Chain Link 420D Split Link. DID is an OEM of many Japanese and European brands. Leading racing teams in the Road and off-road sports rely on the technology of DID.
As a successor to the tried and tested 420 pitch standard chain the 420D used a new technology for manufacturing the rollers. So far the rolls of sheet metal strips have been wound resulting in a sewing site and thus a weak point.
Thanks to the new technology the rolls are made of round material and a sewing area is thus avoided 20-50% higher wear resistance compared to DID 420
Please note we recommend checking original chain/link to ensure it is a 420 pitch chain before ordering as it is not always guaranteed to be compatible.
