CILOYU 60T Sprocket 420 Chain Kit for Coleman CT200U BT200X — 60-tooth alloy steel for increased torque & durability

The CILOYU 60-tooth 420 mini bike sprocket and 420 chain kit is a heavy-duty replacement set engineered to boost torque and durability for Coleman CT200U, BT200X and many Predator-equipped mini bikes.

If you need a reliable drivetrain upgrade for climbing, trail riding or restoring a mini bike, this complete kit includes a 60T rear sprocket plus 420 chain segments (90 links and 42 links) sized to fit many 196–212cc Predator-style engines and popular mini bike models. Components are made from automotive-grade alloy steel for improved wear resistance and feature precise pitch for smoother engagement and fewer derailments.

Will this sprocket and chain fit my mini bike model?

This kit is designed for minibikes using a 420 chain with a 1/2" pitch and 1/4" roller width; it fits many Coleman Powersports CT200U and BT200X variants as well as brands like Baja, Hensim, Massimo and TrailMaster. Note the rear sprocket has four mounting holes — it will not fit frames built for three-hole sprockets. Always confirm bolt pattern and chain size before ordering.

• Chain size: 420 (pitch 1/2", roller width 1/4", roller diameter 5/16")
• Included chain lengths: 90-link + 42-link segments
• Sprocket: 60 teeth, four-hole mounting pattern
• Compatible engines: Predator 196cc–212cc and similar 6.5hp units

How will a 60T sprocket change ride performance?

Swapping from a smaller factory sprocket (for example 50T) to a 60T increases torque at the wheel and lowers top speed, which helps when climbing hills, handling rough terrain, or starting with heavy loads. The result is more controlled, stronger acceleration at lower gears without exceeding engine limits.

• More low-end torque for climbs and uneven ground
• Reduced top speed for safer, controlled rides
• Better traction and engine load handling on steep grades

What materials and build quality can I expect?

CILOYU uses automotive-grade alloy steel for both the sprocket and chain to improve strength and corrosion resistance compared with economy parts. Machining tolerances ensure accurate tooth pitch and smooth chain engagement to minimize skipping and premature wear during use.

• Alloy steel construction for high strength and longevity
• Precisely cut teeth for reliable chain meshing
• Surface treatment to resist rust and abrasion

How should I confirm compatibility and install the kit?

Measure your current chain pitch and roller width, check the number of sprocket mounting holes, and compare engine and frame fitment notes. Installation is standard for minibike drivetrains: remove the old chain and sprocket, fit the new 60T sprocket to the hub, size and join the chain, then set proper tension and alignment.

• Verify 420 chain pitch and four-hole sprocket pattern
• Tools needed: socket set, chain breaker/press, torque wrench
• Adjust chain tension per manufacturer recommendations

Who is this for: Riders, mechanics and minibike restorers who want a dependable drivetrain upgrade for better hill-climbing and torque on Coleman CT200U, BT200X and compatible Predator-style minibikes. This kit suits owners replacing worn parts, customizing gearing for trail use, or preparing a mini bike for heavier loads where low-end power and durability matter.
