YOXUFA 420 Chain 132-Link Red for 50–125cc Pit Bikes & ATVs — Alloy Steel, Includes Master Links & Breaker

YOXUFA 420 Chain 132 Link is a heavy-duty replacement chain kit designed to fit a wide range of 50cc–125cc pit bikes, ATVs, mini bikes and small go-karts, supplied with master links and a chain breaker for custom length adjustments.

This replacement 420 chain comes in a vivid red finish and includes everything needed to install and trim the chain to your vehicle: a complete 132-link length, ten master links, a thimble, and a compatible chain breaker tool. Constructed from alloy steel with surface treatments for improved wear resistance, the chain is intended for small-displacement four-stroke machines commonly used in off-road and recreational riding. The listing emphasizes cross-brand fitment to many Chinese-made and popular mini-bike and ATV models.

Which bikes and vehicles will this 420 chain fit?

The 132-link 420 chain is built for mini and small-displacement machines. It covers a broad set of models from manufacturers commonly used in the pit-bike and mini ATV market, plus several mini bike and go-kart platforms after refit.

• Compatible with 50cc–125cc pit dirt bikes and ATVs including SSR, TaoTao, Coolster, Apollo, Baj a-type clones, Kazuma, SYX and Roket models.
• Fits common Honda-style small frames like CRF50/CRF70/CRF80 and XR50/XR70 when chain size matches.
• Works as a replacement on mini bikes and go-karts such as Coleman CT200U series, Baja MB165/MB200, Hensim MB165/MB200 and similar models after proper refit.
• Verify sprocket tooth count and axle spacing before installation to confirm fitment.

How durable and reliable is the chain for off-road use?

The chain is manufactured from alloy steel and receives a surface hardening process intended to resist wear and extend service life. While not a branded OEM chain, the construction focuses on toughness for trail and recreational riding where moderate loads and debris exposure are common.

• Alloy steel links for strength under repeated loads and accelerations.
• Surface treatment to improve resistance to abrasion and corrosion in muddy or dusty conditions.
• Comes in a full-length 132-link size so you can set the correct tension by removing links as needed.
• Includes ten master links to secure joints and distribute spares for future repairs.

What tools and items are included, and how do I shorten the chain?

The kit ships with a manual chain breaker compatible with 420–530 chains, so you can remove pins and shorten the chain to match your sprockets and swingarm length. A thimble and multiple master links are included to finish the connection cleanly.

• 1 × 420 chain (red) — full 132-link length ready to trim.
• 10 × 420 master links — spare links included for secure joints.
• 1 × 420 chain breaker tool — aligns pins and pushes them out safely; instructions pictured in the listing.
• 1 × 420 thimble for a neat, reinforced loop where applicable.

How should I inspect and maintain this chain after installation?

Regular checks and basic upkeep will keep the chain performing reliably. Inspect for proper tension, even wear across links, and corrosion; lubricate periodically and replace if pins or rollers show significant play.

• Check tension and alignment after the first 50–100 miles and adjust as the chain seats.
• Lubricate the chain with a suitable chain lube to reduce friction and corrosion.
• Look for tight spots, bent links, or excessive elongation and replace if detected.
• Keep sprocket tooth profiles matched — replace sprockets if teeth are hooked or worn.

Who is this for: This YOXUFA 420 chain kit is aimed at owners of small off-road bikes, ATVs, mini bikes and go-karts who need an affordable, full-length replacement chain with tools and spare master links included. It suits hobbyists and weekend riders who perform their own maintenance and want the flexibility to refit chain length for a variety of Chinese-brand and aftermarket platforms.
