CILOYU 35 Mini Bike Chain 140-Link Kit for Coleman CT100U — Alloy-Steel, Includes Master Links & Chain Breaker

CILOYU 35 Chain Mini Bike 140 Links is a heavy-duty replacement chain kit designed to restore drive power on Coleman CT100U and other popular mini bikes.

If your minibike’s original chain is stretched, rusted, or worn, this CILOYU assembly brings a robust, corrosion-resistant alloy-steel option that includes everything needed for installation. The kit arrives as a 140-link 35 chain and includes spare master links plus a handheld chain breaker so you can size and fit the chain quickly. It’s engineered to match the pitch and tensile needs of many small off-road and recreational minibike engines without extra sourcing of tools or links.

Will this chain fit my Coleman CT100U or similar minibikes?

Yes — the 35 chain pitch and 140-link length are intended for common minibike sprockets used on models like the Coleman CT100U and other small-frame bikes. Compatibility spans several brands and engine sizes listed by CILOYU, but always check sprocket tooth count and center distance before trimming links.

• Designed for 35 pitch sprockets commonly found on mini bikes
• Compatible with Coleman CT100U, CC100X, and many Baja/Motovox models
• 140 links provide extra length for custom fitting and trimming
• Includes spare master links to match axle and sprocket setups

How durable is the CILOYU alloy-steel chain and what maintenance is required?

The chain is manufactured from alloy steel with surface treatments to resist wear and corrosion, which increases service life compared to untreated links. Routine lubrication and correct tensioning are still required to maximize lifespan and keep drivetrain noise and wear to a minimum.

• Alloy-steel construction for improved strength and wear resistance
• Surface-treated to reduce rust and abrasion over time
• Regular lubrication and occasional tension checks recommended
• Replace master links if they show elongation or damage

What tools and parts come with the chain for installation?

The kit includes a manual chain breaker and five 35-chain master links so you can shorten the chain to the correct length and secure it reliably. With those items included, you can complete most installations with only basic hand tools, avoiding a separate trip to the parts store.

• 1 x 140-link 35 chain ready to be sized
• 5 spare 35 master links for secure joining
• 1 manual chain breaker for pin removal and link positioning
• Installation requires common wrenches and pliers found in most tool kits

How do I know how many links to remove and when to replace the chain again?

Measure center distance between front and rear sprockets and fit the chain around both sprockets to determine needed length; use the included chain breaker to remove excess links. Replace the chain when it shows visible elongation, excessive side play, or damaged rollers — especially if it skips teeth under load.

• Fit chain loosely over sprockets, pull ends together, and mark excess links
• Use chain breaker to remove links cleanly and attach master link
• Inspect for elongation, rust pitting, roller damage to decide replacement
• Re-check tension after a short test ride and retighten if needed

Who is this for: This CILOYU 35 chain kit is aimed at minibike owners, DIY mechanics, and small-powersport repair shops needing a reliable, ready-to-fit replacement for Coleman CT100U-style machines and similar models from Baja, Motovox, and other compatible brands. It’s especially useful if you want an all-in-one solution that includes spare master links and a chain breaker so you can size and install the replacement without hunting for separate parts.
