YOXUFA #35 Roller Chain 140‑Link for Mini Bike & Small Engines — Heavy‑Duty with 10 Master Links

YOXUFA #35 roller chain is a 140-link drive chain (70 internal + 70 external) built to replace worn or incorrect chains on a wide range of mini bikes and small engine powersports models.

This heavy-duty #35 roller chain from YOXUFA is made for minibikes fitted with small displacement engines such as Predator 79cc, 97cc and 100cc and OEM-style models including Coleman CT100U, CC100X, Baja Doodle Bug DB30 series, Motovox MBX10/MBX11, Monster Moto variants, Mega Moto classics and select Realtree RT100 bikes. Supplied with ten master connecting links, the 140-link length gives you enough material to size, shorten or lengthen the drive chain to match your sprockets and frame layout.

How do I confirm #35 is the correct chain size for my mini bike?

Check your existing chain markings, measure pitch and width, and compare with the chain supplied. #35 chain has a 3/8" pitch and a narrow plate profile typical of small powersports drives.

• Inspect original chain markings or part number.
• Measure pitch (center-to-center between pins ≈ 3/8").
• Confirm sprocket tooth thickness matches #35 specifications.
• Compare overall chain length to the 140-link package before trimming.

What tools and steps are needed to install or shorten the chain?

Basic hand tools allow installation: a chain breaker or bolt cutters for removal, pliers for connecting links, and a wrench set to access axle and tensioner bolts. Follow safe jacking and support practices before removing the old chain.

• Use a chain-break tool or punch and hammer to remove excess links.
• Fit supplied 35# master links to reconnect the chain securely.
• Adjust rear axle or tensioner to set proper chain slack (typically 1/2"–1").
• Rotate wheels to inspect engagement and ensure smooth operation.

Which models and engines is this YOXUFA chain compatible with?

The chain is specified for a broad range of small-frame minibikes and common aftermarket engines. It’s intended as a replacement or spare for popular consumer mini bike models and standard small-engine drivetrain setups.

• Coleman CT100U and CC100X mini bikes.
• Baja Doodle Bug / Blitz / Dirt Bug / Viper DB30 series.
• Motovox MBX10 and MBX11 models; Monster Moto MM-B80/MM-B105.
• Mega Moto Classic MM-B80/MM-B105 and Realtree RT100 compatible installations.

How many connecting links are included and why that matters?

YOXUFA includes ten 35# master connecting links with the chain, so you can assemble the chain quickly, add temporary links for test fitting, or retain spares for future repairs. Multiple links simplify trimming and rejoining during installation.

• 140 total links supplied (70 internal + 70 external) for flexible sizing.
• 10 master links included for secure reconnection and spares.
• Allows progressive lowering of length without needing immediate additional links.

Who is this for: The YOXUFA #35 roller chain is aimed at DIY owners, small-powersports mechanics and minibike assemblers who need a reliable replacement drive chain for common consumer minibike models and small aftermarket engines. If you maintain or restore Coleman, Baja, Motovox, Monster Moto, Mega Moto or similar minibikes and require a full-length #35 chain with spare master links for customization and repairs, this chain provides the length and hardware needed to get your drivetrain back into service.
