Buying Guide

Choose the correct series and pitch

Match the chain series (420 for the entries here) and pitch to your sprockets and motorcycle manufacturer specifications to ensure proper fit and safety

Pick the right link count

Select a link count that accommodates your rim and sprocket combination—longer chains (higher link counts) allow more adjustment and are commonly offered in 100–140 links for motocross

Consider plate and pin materials

Look for chrome-moly or similar high-strength steels in racing chains for improved tensile strength and wear resistance under track conditions

Decide on sealed vs non‑O‑ring

Non-O-ring chains reduce friction and weight, often preferred in racing, while sealed designs retain lubricant longer for lower maintenance in other use cases

Evaluate finish and corrosion resistance

Gold or plated finishes can offer additional corrosion protection and ease of cleaning after muddy conditions common to motocross tracks
