YOXUFA 420 Drive Chain for Mini Bikes & ATVs, 132-Link Red with Master Links & Chain Breaker

YOXUFA 420 Chain (132 links, red) is a heavy‑duty replacement drive chain built to fit a wide range of 50cc–212cc mini bikes, dirt bikes, ATVs and go‑karts.

This replacement 420 chain arrives ready for installation with a full set of spare master links, a thimble and a compatible chain breaker for custom length adjustments. Made from alloy steel with a wear‑resistant surface treatment, it’s designed to withstand frequent riding conditions on small displacement engines and off‑road use. The bright red finish helps with quick visual inspection and adds an aftermarket accent to your drivetrain.

Which machines will this 420 chain actually fit?

The chain has broad cross‑brand compatibility for many Chinese and utility mini machines. It is sized to work with popular 50cc–125cc pit dirt bikes and many 4‑stroke mini ATVs, and — after refit — it suits a number of mini bike models and small trail bikes.

• Fits SSR, TaoTao, Coolster, Apollo, Baja, Kazuma and similar 50cc–125cc pit bikes.
• Compatible with Coleman CT200U, BT200X and many mini bike models from Baja, Hensim and Massimo.
• Works on small go‑karts and predator 212cc applications where 420 specification is appropriate.
• 132 links supplied; remove links for shorter swingarm or sprocket spacing when needed.

How durable is the chain and what makes it long‑lasting?

The chain is constructed from alloy steel and receives a surface hardening process to resist abrasion and extend service intervals. Heavy‑duty plates and reliable rivet construction reduce stretch and premature wear when used with proper lubrication and alignment.

• Alloy‑steel plates engineered for impact and fatigue resistance.
• Wear‑resistant surface treatment for longer life between replacements.
• Supplied multiple master links for secure, repeatable joins.
• Chain breaker included to avoid forcing pins and damaging plates during length adjustment.

What comes in the package and how do I shorten the chain?

The kit is supplied with practical accessories to make fitting straightforward: spare master links, a thimble for a clean connection and a chain breaker that fits 420–530 sizes. To shorten, align the chain center pin with the breaker hole, retract the pressure pin into the nut, then drive out the chosen pin and reconnect using a master link.

• 1 x red 420 chain (132 links) ready to trim and install.
• 10 x 420 master links for secure reconnection after resizing.
• 1 x 420 chain breaker compatible with 420–530 chains to remove pins safely.
• 1 x thimble to protect the fastened end and improve alignment.

Will I need extra tools or parts to install this chain?

Basic hand tools plus a torque wrench are typically sufficient; the included chain breaker and master links eliminate the need for specialized pin presses. You should verify sprocket tooth counts and check for worn sprockets before reuse—replacing worn sprockets at the same time prolongs chain life.

• Required: wrench set, pliers and possibly a torque wrench for axle nuts.
• Recommended: chain lubricant and sprocket inspection/replacement if teeth are worn.
• Chain breaker and master links included to simplify the process.

Who is this for: Riders, mechanics and DIY enthusiasts who maintain small displacement off‑road bikes, ATVs, go‑karts and mini bikes will value this YOXUFA 420 chain. It suits owners replacing stretched or damaged chains on Chinese‑made pit bikes and many mini bike platforms, and for those who prefer a bright, durable aftermarket option with tools included for on‑vehicle adjustment.
