The design of this motorcycle chain has been optimised with the aim of reducing the loss of grease through the gaps between the pin and link plate of a standard roller chain. For this purpose, the flat link plate has been modified so that it is produced with an additional convex plate on the outer link plate. This innovative design prevents dust penetration and the loss of lubricant. In addition, the teflon (PTFE) coating of the chain link plates offers excellent sliding properties, is rust-free and acts as an adhesion barrier.
