Buying Guide

Choose the correct size and link count

Confirm your motorcycle’s required 420 chain size and precise link count — options here range from 104 to 140 links — to avoid re-sizing or cutting the chain

Match chain construction to your use

Non-O-ring chains are lighter and common in MX racing for easier maintenance and reduced friction, but require more frequent cleaning and lubrication

Consider brand reputation

RK Racing is a long-standing manufacturer in powersports chains; choosing reputable brands helps ensure consistent quality and accurate link counts

Compare price per link

Use price relative to link count to evaluate value — listed chains range roughly $33 to $45 for 104–140 links, so per-link cost varies with length

Check customer ratings

Look for consistent user feedback on durability and fit; the selections here share a 4.6★ average rating, indicating reliable performance across options
