MRELC 420 Motorcycle Chain 132-Link Kit — 59in 1/2in Pitch with Chain Breaker & 10 Master Links

MRELC 420 Motorcycle Chain 132 links with chain breaker and connector kit — a ready-to-fit replacement chain for 50–212cc ATVs, dirt bikes, go-karts and mini bikes.

This heavy-duty 420 roller chain arrives with 132 links (66 internal + 66 external), a chain breaker tool and 10 connector links so you can size and install it on-site. Engineered to match common 420-spec sprockets, the chain works across a wide range of Chinese and small-displacement power sport machines — from SSR and TaoTao to Coolster, Roketa and many pit bike models. The package is built for riders who need a complete repair or upgrade kit without hunting down separate parts.

How do I know this chain fits my bike or ATV?

Check your vehicle’s chain number and sprocket pitch; the MRELC chain is a 420 specification with a 1/2" pitch, 1/4" roller width and a total length of 59" in the supplied 132-link configuration. Many 50–125cc and common 212cc Chinese engines use 420 chains, but confirming the chain number stamped on your old chain or your owner’s manual ensures compatibility.

• Chain number: 420 (pitch 1/2").
• Roller width: 1/4" — matches standard 420 sprockets.
• Total length: 59" in 132 links (removable links to shorten).
• Suitable for SSR, TaoTao, Coolster, Roketa, Baja, and similar models.

What tools and parts come with the chain kit for installation?

The kit includes a handheld chain breaker for removing or adding links and ten connector (master) links so you can finish the join securely. Because many small bikes require shortening, the supplied breaker lets you trim the chain to the correct length and reattach it without needing a full workshop.

• 1 x 420 roller chain (132 links).
• 1 x chain breaker tool suitable for 420–530 sizes.
• 10 x 420 connector (master) links included as spares.
• Links removable to fit 50cc–212cc bikes, ATVs, go-karts and mini bikes.

How durable is the MRELC 420 chain and what can I expect in service?

The chain is built to standard 420 dimensions and intended for everyday off-road and small-power applications; it’s not a specialized high-performance race chain but offers reliable service for trail riding, yard work, and recreational use. Proper tensioning and routine lubrication will extend life, and the included spare links and breaker make field repairs fast.

• Standard 420 construction for common power-sports use.
• Requires routine lubrication and correct tension for best life.
• Includes spare connectors for quick roadside fixes.
• Breaker tool fits a range of chain sizes up to 530 for versatility.

Who is this for? The MRELC 420 Motorcycle Chain 132 Links kit is aimed at riders, DIY mechanics, and fleet owners of small-displacement ATVs, pit bikes, go-karts and mini bikes who want a complete, on-hand replacement chain. It suits anyone who needs a field-serviceable chain that can be shortened and joined quickly using included tools and spare connectors — especially owners of Chinese-brand or common 50–125cc and 212cc models seeking an affordable, ready-to-install solution.
