CILOYU 35 Roller Chain Replacement Kit 140-Link for Coleman CT100U — Alloy-Steel with Tensioner & Master Link

The CILOYU 35 roller chain kit with 140 links is a direct-fit replacement for Coleman CT100U and compatible Baja mini bikes, supplying a durable alloy-steel chain, tensioner, master link and chain breaker for straightforward installation and longer service life.

If your mini bike is sporting a worn or stretched chain, this complete CILOYU replacement kit is built to restore drivetrain reliability and reduce downtime. Designed to match the 35 pitch size used on many small off-road and utility mini bikes, the kit bundles a full-length 140-link chain with a rubber-and-metal tensioner plus an installation tool and spare master link so you can repair or replace the chain at home.

Which models and engines does this chain fit?

This 35 roller chain is engineered to fit Coleman Baja Motovox mini bikes and several other popular models that use the same pitch and width. It is compatible with Coleman Powersports CT100U, CC100X and a range of Baja Motorsports, Motovox and Monster Moto mini bikes listed below.

• Fits engines commonly found on small minibikes: Predator 79cc, 97cc, 98cc, 100cc.
• Compatible models include Coleman CT100U, CC100X, Baja Doodle Bu* DB30 series, Motovox MBX10/MBX11.
• Fits Monster Moto models such as MMB80 and MMB105 when they use a 35 pitch chain.
• 140-link length provides scope for cutting to size for front or rear sprocket configurations.

How does the kit improve durability and reduce maintenance?

The chain itself is crafted from premium alloy steel and treated for better wear and corrosion resistance, helping it withstand outdoor conditions and the shock loads of off-road riding. The included rubber-and-metal tensioner smooths chain movement and reduces side-to-side wear, while the spare master link and chain breaker make future servicing simpler.

• Alloy steel construction with protective surface treatment for corrosion resistance.
• Tensioner with rubber face reduces metal-on-metal contact and noise.
• Extra master link included for quick repairs during rides or maintenance.
• Chain breaker tool allows clean removal of excess links for custom length.

What should I expect during installation and adjustment?

Installation is straightforward for anyone comfortable with basic minibike maintenance. Use the chain breaker to remove excess links to match your sprocket spacing, attach the master link, then mount the tensioner and adjust until the chain has proper slack. Check alignment, re-torque fasteners and recheck tension after a short test ride.

• Cut the chain to the correct length using the supplied chain breaker.
• Install the master link and clip, ensuring the link faces the correct direction.
• Mount the tensioner and set chain slack according to your mini bike manual.
• Recheck and re-tighten after the first ride to account for initial settling.

Who is this for: The CILOYU 35 chain kit is aimed at mini bike owners, mechanics and hobbyists who need a reliable, full-length replacement chain compatible with Coleman CT100U and similar Baja-style models. If you service minibikes for family, friends or small fleets and prefer having a complete installation kit (tensioner, master link and chain breaker) on hand, this product gives you the parts and tools to restore drivetrain performance without sourcing components separately.
