Pro Taper 420MX Premuim Gold Series Chains - Lg. 134
The Pro Taper 420MX Premium Gold Series chain fits the Grom 125 well because Honda specifies a 420-pitch chain for the stock drivetrain, and this 134-link length gives you enough slack to cut to the correct count without coming up short. The X-ring construction holds lubrication longer than standard chains, which matters on a small bike that sees frequent city stop-and-go use. Caveat: "MX" branding means it's optimized for dirt-bike duty, so road riders should inspect it more often for stretch.
