DID 420D Standard Series is a reliable, no-frills 420 drive chain for smaller bikes and setups that use a non O-ring chain. It delivers consistent power transfer with an easy clip-type master link for quick installation.
The DID 420D Standard Series chain is a classic, dependable roller drive chain built for riders who need a straightforward replacement for applications that originally came with a non O-ring chain. With a widely used “standard” construction and an industry chain life index rating of 100, it’s a proven choice for everyday riding where easy servicing and predictable performance matter.
If your bike runs a non-sealed 420 chain, the 420D is a practical solution to restore smooth power delivery to the rear wheel without changing your drivetrain setup. The clip-type master link makes fitting and trail-side servicing simpler, while DID’s manufacturing consistency helps maintain stable alignment and reduced drivetrain hassle when properly adjusted and lubricated.
