D.I.D. 428X120RB 428 Standard Non-Sealed Roller Drive Chain 120 Links

The D.I.D. 428X120RB is a 428-pitch standard non-sealed roller drive chain with 120 links, designed for small-displacement motorcycle and powersports applications up to 125cc. D.I.D. (Daido Industrial Developments) is one of the world's leading chain manufacturers, and this chain delivers reliable, low-friction performance for everyday riding.

Built with solid rollers and manufactured to exacting tolerances, this chain minimizes friction and wear for smooth power transfer. The chain is shot peened and pre-stretched from the factory, reducing the initial break-in elongation period and helping maintain proper tension right out of the box.
