YOXUFA Mini Bike 60T Sprocket & 420 90-Link Chain Kit — 196–212cc Fit, Torque-Boosting Upgrade

YOXUFA Mini Bike Sprocket 60T with 420 90-link chain is a drop-in drivetrain upgrade that increases torque and climbing ability for compatible 196–212cc mini bikes.

If you need a robust replacement sprocket and chain that fits Coleman CT200U/Baja/Predator-powered mini bikes, this YOXUFA kit pairs a precision-machined 60-tooth rear sprocket with a 420-series 90-link chain, a chain breaker tool, and an extra master link for easier installation and longer service life. The larger 60T sprocket changes final drive ratio to favor power and hill-climbing over top speed, and the alloy construction and tooth profile are made to resist wear under load.

How does the 60T sprocket affect my mini bike's performance?

Switching from a smaller rear sprocket (for example, 50T) to this 60-tooth unit increases mechanical advantage, producing stronger low-end torque and easier uphill acceleration. You will notice a reduced top speed but more control on rough or steep terrain.

• Higher torque for climbing and load carrying
• Smoother low-speed throttle response
• Reduced maximum speed compared with smaller sprockets
• Better traction on uneven surfaces

Which mini bikes and engines are compatible with this kit?

This YOXUFA kit was designed to fit a wide range of 196–212cc mini bike platforms and engines that use 420-series chain and a 60T rear sprocket pitch. Check model fitment and physical mounting points before purchase.

• Coleman CT200U, BT200X, CT200U-EX/EXR, KT196
• Baja Motorsports models: MB165, MB200 (Heat, Mini Baja, Warrior)
• MASSIMO MB200, TrailMaster MB200, Axis M200
• Predator 212/196cc and similar 6.5hp engines using 420 chain

What materials and parts are included in the kit?

The rear sprocket and chain are made from a durable metal alloy and precision-machined teeth to resist wear and help keep the chain seated securely. The kit includes installation aids so you can replace the drivetrain without specialty tools.

• Precision-machined 60T alloy rear sprocket
• 420-series chain, 90 links (ready to size)
• Chain breaker tool for link removal and resizing
• Extra master link for quick connection

How easy is installation and maintenance?

Installation is straightforward for anyone with basic mechanical experience: remove the wheel, replace the sprocket, size the chain with the included breaker, and snap in the master link. Routine inspection and lubrication extend life and ensure safe operation.

• Remove wheel and unbolt old sprocket
• Fit new sprocket and torque fasteners to spec
• Trim chain to correct length with chain breaker tool
• Install master link and check alignment and tension

Who is this for? This YOXUFA 60T sprocket and 420 90-link chain kit is for mini bike riders, hobbyists, and small-engine mechanics who want more torque and reliable drivetrain parts for 196–212cc platforms. It suits owners of Coleman, Baja, Massimo, TrailMaster, Axis, and Predator-powered mini bikes who need a durable replacement or an upgrade for hill-climbing, trail riding, or heavier-load use. If you prioritize low-end power and rugged construction over top speed, this kit is a practical, easy-to-install choice.
