D.I.D 420D Non-Sealed Chain — 78 Links

An entry-level non-sealed roller chain for utility, pit, and low-displacement use where occasional re-lubing is part of the routine.

• Manufactured in Japan to D.I.D quality control standards.
• Sized 420 for small-bore scooters, dirt-track, and play bikes.
• Best suited to bikes that see regular maintenance.

Intended use: street utility, commuter, off-road.

Pitch / length: 420 pitch / 78 links (verify against your owner's manual; chains are cut down at install if longer than OEM spec).
