YOXUFA 420 Chain 132-Link Gold Replacement Kit for 50–150cc Minibikes & ATVs, Includes Master Links & Breaker

YOXUFA 420 Chain 132 Links is a heavy-duty gold replacement chain kit for 50cc–150cc mini bikes, pit bikes, ATVs and go-karts that includes links, a breaker and a thimble for on-site length adjustments.

When your small-engine ride needs a reliable drive chain, this complete 420 chain kit covers common Chinese and aftermarket minibikes, pit bikes, ATVs and mini-quad applications. Built from alloy steel with a wear-resistant finish, the 132-link gold chain ships with ten master links, a chain breaker tool and a thimble so you can trim and install the correct length without searching for parts.

Which vehicles will this 420 chain fit?

This chain is designed for broad compatibility with many 50cc–150cc small-engine vehicles. It fits common models from brands like SSR, TaoTao, Coolster, Apollo and multiple mini bike and go-kart platforms after sprocket or refit adjustments.

• Direct fit for SSR 110/125 and Coolster/TaoTao 110cc–125cc pit bikes and ATVs
• Compatible with CRF50/70/80-style small-frame machines and similar replacements
• Works with mini bikes like Coleman CT200U, Baja MB200, Massimo MB200 after refit
• Also suitable for Roket*, Hensim, TrailMaster and many Chinese-made 4-stroke minis

How durable and resistant is the chain?

The chain uses alloy steel construction and a surface treatment meant to resist wear and extend service life. While not indestructible, the heavier plates and treated finish reduce abrasion compared with untreated chains in similar size categories.

• Alloy steel links for improved tensile strength and fatigue resistance
• Wear-resistant surface treatment to slow abrasion and corrosion
• Gold finish for visibility and basic rust protection
• Intended for normal off-road, trail and park use on compatible machines

What comes in the kit and how do I adjust length?

The kit includes everything needed to size and fit the chain to your sprockets: the 132-link chain, master links, a chain breaker and a thimble. The supplied chain breaker supports 420–530 chains and lets you remove excess links; follow alignment of the center pillar and bottom hole when pressing pins out to avoid damage.

• 1 x 420 chain (132 links) in gold finish
• 10 x 420 master links for secure joining and future repairs
• 1 x 420 chain breaker tool compatible with 420–530 chain sizes
• 1 x 420 thimble to aid routing and end protection during installation

What installation tips improve lifespan and performance?

Proper installation, tension adjustment and routine lubrication significantly extend chain life. Ensure sprockets are in good condition, align sprockets during fitting and use the correct tension range recommended by your vehicle manufacturer.

• Check sprocket tooth wear; replace both sprockets and chain together if worn
• Use the included breaker carefully—retract the pressure pin into the nut between uses
• Set correct chain slack and recheck after a short initial ride
• Apply suitable chain lubricant regularly for off-road conditions

Who is this for: Riders and hobbyists who own mini bikes, pit bikes, ATVs or small go-karts built on common 420-chain platforms and need a complete repair or upgrade kit. It’s aimed at DIY mechanics who want a durable, ready-to-size replacement including master links and a breaker tool, and for anyone replacing worn chains on Chinese-manufactured or refitted small-engine machines.
