YOXUFA 420 Motorcycle Chain is a 132-link, 59-inch replacement chain kit designed for small-displacement pit bikes, mini ATVs, and go-karts, supplied with a chain breaker and connector links for on-bike installation.

This heavy-duty 420 chain kit provides a ready-to-install drivetrain solution for a wide range of 50cc–212cc four-stroke Chinese and Japanese mini bikes and quads. Built to match standard 420 pitch and roller dimensions, the set includes the full-length chain, a chain breaker tool and ten connector links so you can size the chain to your sprockets without searching for extra parts.

Will this chain fit my pit bike, mini ATV or go-kart?

Compatibility is broad but depends on the original chain spec of your vehicle. The YOXUFA 420 chain uses a 1/2" pitch and 1/4" roller width, typical for many small-displacement models, so confirm your OEM chain number or measure before ordering.

• Fits 50cc–212cc small four-stroke bikes and quads commonly using 420 chains
• Compatible examples: SSR, TaoTao, Coolster, Apollo, Baja, Roketa, Kazuma models
• Also suitable for CRF50/70/80 and XR50/70/80 style minis that use 420 chains
• Check sprocket thickness and pitch match: 0.227" sprocket thickness recommended

How do I size and install the 132-link chain?

The chain arrives full-length with 132 links (66 internal + 66 external) so you can trim to your required length. Use the included chain breaker to remove unwanted links and the connector links to rejoin the chain; always ensure proper tension and lubrication after installation.

• Total length: 59 inches with 132 links for flexible sizing
• Includes 1 chain breaker tool to push out pins safely on-site
• Ten 420 connector links supplied for secure reassembly
• After fitting, set correct slack per your vehicle manual and lubricate rollers

What are the physical specifications and durability features?

The YOXUFA chain follows standard 420 dimensions so sprockets and tensioners designed for 420 chains will interface correctly. The roller diameter, pitch and width align with common mini bike designs to keep engagement smooth and reduce premature wear when maintained properly.

• Chain number: 420; pitch: 1/2"; roller width: 1/4"; roller diameter: 5/16"
• Sprocket thickness spec: approximately 0.227" to match chain plates
• Breaker tool rated for 420–530 chain pin removal for versatility
• Supplied connectors allow a reliable mechanical join without special crimps

Who is this for? This YOXUFA 420 chain kit is aimed at riders, mechanics and hobbyists who need a full-length replacement chain for small-displacement motorcycles, ATVs, mini bikes, go-karts and quads. It’s especially useful if you want a complete kit—chain, breaker tool and connector links—in one purchase so you can size and fit the chain at home or trackside without scavenging parts.
