CILOYU mini bike #35 chain 140-link with red finish and integrated mini tensioner — fits CT100U MBX10

CILOYU's #35 red mini bike chain with integrated mini chain tensioner is a 140-link, alloy-steel replacement designed to restore smooth, reliable drivetrain performance on compatible small-frame bikes.

This replacement assembly pairs a heat-treated #35 chain with a compact rubber-and-metal tensioner so you get both the correct length and the ability to fine-tune chain slack in one purchase. It’s made for a range of Coleman, Motovox, Baja Motorsports and similar mini bikes that use a #35 chain and benefit from a durable, corrosion-resistant finish. The bright red finish makes it easy to inspect for wear while the included tensioner reduces excessive vibration and helps prevent derailment during use.

Which mini bikes is this CILOYU #35 chain compatible with?

The chain is intended for small displacement mini bikes that accept a #35 chain ratio and 140-link length. Confirm your bike’s required chain size and link count before ordering to ensure a correct fit.

• Compatible models: Coleman CT100U, CC100X, Baja Motorsports Doodle Bug series, Motovox MBX10/MBX11
• Works with engines around Predator 79–100cc commonly used in mini bikes
• Suitable for replacement on most mini frames requiring a #35 chain, 140 links

How does the mini bike chain tensioner improve drivetrain performance?

The included tensioner combines a rubber guide with a metal bracket to maintain correct chain tension and alignment. Keeping the chain properly tensioned reduces skipping, slapping, and premature wear on sprockets and bearings.

• Rubber contact surface lowers friction and extends chain life
• Adjustable mount allows quick tension changes without disassembly
• Helps prevent the chain from jumping under load or during rough terrain

What materials and durability features are built into this replacement chain?

CILOYU engineered the chain from alloy steel with a factory surface treatment to resist corrosion and abrasion. The result is a balance of tensile strength and wear resistance suited to recreational and light utility use.

• Alloy-steel construction for higher fatigue strength
• Protective finish reduces rust and simplifies inspection
• Heat-treated links for consistent wear characteristics

How do I check that 140 links and #35 size are right for my bike?

Measure your current chain or consult your owner’s manual to verify both pitch (#35) and overall link count (140). If you don’t have the original chain, measure the distance from center of front sprocket to rear sprocket and add a few inches for tensioner adjustment.

• Check stamped size on existing chain or manual specification
• Count links on removed chain or use a chain-measuring tool
• Allow for a few links slack for proper tensioning with the included tensioner

Who is this for: This CILOYU #35 red chain with mini bike tensioner is designed for owners of Coleman, Motovox, Baja Motorsports and similarly configured mini bikes who need a full-length (140-link) replacement. It’s a solid choice for weekend riders, DIY mechanics, and anyone looking to replace a worn or rusty chain while adding a compact tensioner to keep the drivetrain running smoothly. Verify chain pitch and link count for compatibility before purchase.
