YOXUFA 420 Chain 132-Link Red Replacement Chain Kit for 50–212cc Dirt Bikes ATVs with Master Links & Breaker

YOXUFA 420 Chain is a heavy-duty, 132-link replacement chain kit in red designed to fit a wide range of small-displacement dirt bikes, ATVs, mini bikes and go-karts.

This complete 420 chain assembly gives you a corrosion-resistant, alloy-steel drive chain plus all necessary accessories to size and install it. Built for common 50cc–212cc platforms from manufacturers such as SSR, Taotao, Apollo, Coolster, Coleman and Baja, the kit includes a chain breaker and master links so you can trim to the exact length required for your machine. The red finish and wear-resistant surface treatment combine function with a visual upgrade for your drivetrain.

Which machines will this 420 chain fit?

This chain is engineered for broad compatibility with small four-stroke engines and mini-bikes. It fits many pit dirt bikes, ATVs, four-wheelers, and go-karts in the 50cc–212cc range after proper chain length adjustment.

• Fits SSR 110/125, Taotao and Coolster 110–125cc pit bikes and ATVs
• Compatible with CRF50/70/80 and XR50/70/80-style sprocket spacing
• Usable on Coleman CT200U, Baja MB165/MB200, Hensim/Massimo/TrailMaster mini bikes
• Works with Predator 212cc and similar small-engine go-karts after refit

How durable and well-made is the chain?

The YOXUFA 420 chain is manufactured from alloy steel with a surface process that increases wear resistance and extends service life. Pins and sideplates are designed for repeated loading typical of off-road use, while the red coating reduces surface corrosion.

• Alloy-steel construction for strength under load
• Wear-resistant surface treatment to slow abrasion
• Appropriate for off-road and recreational use with regular maintenance
• Comes as a 132-link assembly to cover most common sprocket setups

What’s included and how do I size the chain?

The kit arrives ready to be shortened and installed: 1 red 420 chain, ten 420 master links, a 420 chain breaker and a thimble for assembly. The included breaker is compatible with chains in the 420–530 range and lets you remove links for a custom fit.

• One 132-link 420 chain in red for visual and corrosion protection
• Ten master links so you can rejoin sections without welding
• Chain breaker tool—retract the pressure pin into the nut and align the pillar with the breaker hole before pressing
• Thimble for stabilizing the master link during assembly

How should I maintain and install the chain to maximize life?

Proper installation and routine care will keep the chain running longer and reduce wear on sprockets. Inspect for correct tension, lubricate regularly with a chain lube, and check master-link pins after the first few rides to ensure they remain secure.

• Trim to length using the provided chain breaker, then secure with a master link
• Adjust tension per your vehicle’s manual: not too tight, not too loose
• Lubricate frequently, especially after wet or dusty rides
• Inspect sprockets and chain for wear; replace if teeth are hooked or links bind

Who is this for: Riders and mechanics who want a robust, ready-to-install replacement chain for small-displacement dirt bikes, ATVs, mini bikes and go-karts. This kit suits hobbyists who need a universal 420 chain with tools included, owners of older or modified machines that require custom chain lengths, and anyone looking to refresh drivetrain appearance with a red, wear-resistant finish. It is not a sealed O-ring chain for high-performance racing applications; instead it is a durable, serviceable replacement for recreational and utility use.
