RZEOZU Heavy-Duty #35 Mini Bike Chain — 140-Link Silver Kit with Breaker for Coleman CT100U/GMB100

RZEOZU Heavy Duty Mini Bike #35 chain kit is a reinforced 140-link silver chain with master links and a chain breaker engineered to replace worn drive chains on Coleman CT100U, GMB100 and many 79–105cc mini bikes.

If your minibike’s original chain is stretched, noisy, or unreliable, this replacement kit supplies a full-length #35 roller chain plus installation accessories so you can restore smooth power transfer. The chain is heat-treated and plated for wear resistance and a polished silver finish. It arrives with extra master links and a compact chain breaker tool to size the chain to your sprockets without needing a separate workshop visit.

Which mini bikes and engines will this chain work with?

This chain kit is built around a standard #35 roller chain specification, making it compatible with a broad range of small-frame bikes and 79–105cc single-cylinder engines. It matches common drive ratios found on Coleman, Baja, Motovox, Monster Moto and similar models.

• Compatible models: Coleman CT100U, CC100X, Baja Motovox MBX10/MBX11, Doodle Bug DB30 series, Monster Moto MM‑B80/MM‑B105.
• Engine compatibility: Predator-style 79cc, 97cc, 98cc, 100cc and similar small engines.
• Chain size: ANSI #35, 140 links included — trim to length as needed.

How does the kit make installation easier?

The package includes a compact chain breaker and extra master links so you can cut, join and secure the chain on-site without specialized tools. That reduces downtime and keeps the repair straightforward for DIYers and technicians alike.

• Chain breaker included for cutting and pin removal.
• Extra master links for secure, quick reconnection.
• 140-link length gives room to size correctly for varied sprocket combinations.

What materials and treatments improve longevity and performance?

The chain is manufactured from high-strength steel that undergoes heat treatment and electroplating to enhance tensile strength, wear resistance and corrosion protection. The roller design minimizes friction and operates more quietly for cleaner power delivery.

• Heat-treated steel for increased tensile strength.
• Electroplated silver finish for corrosion resistance and a polished look.
• Precision rollers and link geometry to reduce noise and friction.

Will the silver finish affect maintenance or appearance?

The bright silver plating gives the drive system a cleaner, more modern look while helping resist rust. Regular chain lubrication and inspection are still recommended to maximize service life, but the plated surface is easier to wipe clean and maintains an attractive appearance longer than raw steel.

• Silver plating resists corrosion and maintains a polished look.
• Surface is simpler to clean and inspect for wear.
• Visible finish helps spot lubrication needs sooner.

Who is this for: This RZEOZU kit is aimed at riders and mechanics who need a dependable replacement chain for pocket bikes and small-frame minibikes using #35 sprockets — particularly owners of Coleman CT100U, Baja/Motovox, Monster Moto, and similar models who want a durable, ready-to-install chain with the tools required for trimming and joining. It suits DIY enthusiasts who prefer to complete drive-train maintenance at home as well as service shops that stock common replacement parts for entry-level minibikes.
