CILOYU 420 Mini Bike Chain 90-Link Red — Alloy-Steel with Master Link & 15 mm Adjuster

This replacement chain delivers a corrosion-resistant alloy-steel build, a full 90-link length (45 inner + 45 outer links), and includes a removable master link plus a 15 mm chain adjuster so you can install, shorten, and tension the drive chain with confidence. It's engineered to suit a wide range of minibikes and go-karts—where reliable power transfer and simple field serviceability matter most.

Which bikes and engines will this chain work with?

This 420-sized, 90-link chain is designed for common small-engine and mini-bike platforms. It fits Predator 212cc variants plus many Coleman, Baja, Hensim and Massimo mini-bike models—check your sprocket size and chain type before ordering.

• Compatible with Predator 212, 200cc and 196cc engines
• Fits Coleman Powersports CT200U / CT200U-EX / BT200X
• Works on Baja MB165, MB200 and Hensim/MASSIMO/TrailMaster mini bikes
• Confirm #420 chain pitch and sprocket tooth count for exact fit

How durable is the alloy-steel construction and finish?

The chain is manufactured from hardened alloy steel and finished with a wear-resistant surface to extend life under load and resist surface corrosion. That treatment helps reduce abrasion between pins and bushings and delays common wear-related elongation.

• Alloy-steel links for strength under torque
• Wear-resistant surface coating for corrosion protection
• Solid riveted-style connections with a removable master link
• Built to withstand routine maintenance and field repairs

What comes in the package and how do I install or adjust it?

Package contents include the 420 chain with 90 total links, a removable master link for easy joining or shortening, and a 15 mm chain adjuster to help maintain proper tension. Installation requires matching sprocket sizes, removing excess links with a chain tool or pin punch, and setting correct chain slack per your vehicle manual.

• Includes master link for quick assembly/removal
• 15 mm chain adjuster helps prevent slippage and derailment
• Remove links in pairs (inner + outer) to shorten correctly
• Set 1/2–1 inch of slack depending on your chassis spec

How do I know it's the right length and what does "90 links" mean?

The chain is labeled as 90 links, which means it contains 45 inner links and 45 outer links for a total of 90. Some sellers or manuals may count only outer links and list a lower number—verify whether the count is total links or outer-only before comparing.

• 90 links = 45 inner + 45 outer links (total length)
• Measure center-to-center distance and sprocket teeth to confirm fit
• Shorten by removing matching inner/outer link pairs with a chain tool
• Reattach using the supplied master link and secure clip properly

Who is this for: Riders, hobbyists, and small-engine mechanics who need a robust, field-serviceable replacement chain for Predator 212 conversions, mini bikes, and go-karts. If you value durability, easy on-vehicle servicing, and compatibility with widely used mini-bike models, this CILOYU 420 chain with adjuster and master link is a practical, cost-effective drivetrain component.
