Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model
- Coleman CT200U and CT200U-EX
- Coleman BT200X
- Compatible 196cc / 212cc mini-bike layouts using a #420 90-link rear chain
- Modified bikes require direct center-distance and link-count measurement
Product Overview
A chain with frozen links, excessive stretch, missing rollers, or repeated derailment should be replaced before it breaks and damages the case or rider. Worn sprockets, bent tensioner, loose axle, and misalignment must be fixed with it.
This is the rear 90-link chain commonly used from the jackshaft to the rear sprocket. It is different from the shorter 42-link front jackshaft chain and may need sizing on modified bikes.
Confirm #420 pitch, 90-link count, chain width, sprocket tooth profile, rear-chain position, bike model, and stock versus modified gearing. Count links the same way as the service manual.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application that is not shown above.

Match the original part, reference number, dimensions, connectors, mounting points, and product photos before purchase.
Frequently Asked Questions
Q: Is this the short jackshaft chain? A: No. This is identified as the 90-link rear drive chain; the front chain is commonly 42 links.
Q: Can I put a new chain on hooked sprockets? A: It is poor practice because worn sprockets can quickly damage the new chain.
Q: Will it fit after a torque-converter conversion? A: Only if the modified center distance and sprockets still require #420 chain at this length.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
