YOXUFA Mini Bike Sprocket 60T Kit with 420 90‑Link Chain — Direct Fit for Coleman CT200U, More Low-End Torque

YOXUFA's 60-tooth rear sprocket paired with a 420 90-link chain is a direct-replacement drivetrain upgrade for many 196–212cc mini bikes, delivering stronger torque and reliable fitment.

Designed as a full replacement kit for popular small-engine bikes, this package includes a precision-machined 60T sprocket, a 420-format chain with 90 links, a master link, and a chain breaker tool. It’s engineered to swap directly onto Coleman CT200U series models, Predator 196/212cc engines, Baja and TrailMaster mini bikes, Massimo MB200 and similar platforms that use the 420 chain standard. The larger 60-tooth sprocket modifies final drive ratio to favor pulling power without requiring complex modifications.

How does switching to a 60-tooth sprocket change performance?

Moving from a smaller rear sprocket to this 60T increases mechanical advantage at the wheel, producing stronger low-end torque and easier hill-climbing. Top speed will typically decrease slightly while acceleration and load-handling improve, which is useful for off-road or heavy-duty riding conditions.

• More torque for inclines and rough terrain
• Slower top speed but quicker, stronger acceleration
• Improved control when hauling or carrying weight
• Direct bolt-on fit for compatible hubs—no major modification

Will this sprocket and chain fit my Coleman or Predator-powered mini bike?

The kit is intended for mini bikes using a 420 chain around 196–212cc engines; compatibility includes Coleman CT200U, BT200X, CT200U-EX, Predator 212/196cc, Baja MB165/MB200, Massimo MB200, TrailMaster MB200, Axis M200 and similar models. Always confirm your bike uses a 420 chain and the same hub bolt pattern before purchasing.

• 420 chain standard—90-link length included
• Fits many Coleman CT200U variants and Predator 196/212 setups
• Compatible with common mini bike hubs on listed models
• Check bolt pattern and engine sprocket size for exact compatibility

What materials and design features improve durability?

The sprocket is milled from a hardened metal alloy and the chain is made to industry 420 specifications, offering resistance to wear under typical off-road stresses. Tooth profiles are precision cut to maintain chain alignment, reducing the chance of derailment and extending service life with correct maintenance.

• Precision-machined tooth geometry for consistent engagement
• Durable alloy construction resists bending and wear
• 420 chain links treated for longevity under load
• Includes extra master link and chain breaker for maintenance

How difficult is installation and what’s included to help?

Installation is straightforward for anyone with basic mechanical skills and common mini bike tools. The kit supplies the chain, a replacement master link, and a chain breaker to split and size the chain; you’ll need normal socket tools and possibly a torque wrench for final fasteners.

• Comes with chain breaker and spare master link for cutting and joining
• Direct-replacement design minimizes additional parts or fabrication
• Basic hand tools required—no specialty presses needed
• Follow torque specs and chain tension guidance from your bike manual

Who is this for: riders who want stronger low-end performance from their mini bike, mechanics performing drivetrain replacement, and customers updating worn sprockets and chains on Coleman, Predator, Baja, TrailMaster, Massimo and similar small-engine bikes. If you need more pulling power for hills, off-road work, or to recover traction in uneven terrain, this YOXUFA 60T sprocket and 420-90 chain kit provides a practical, durable upgrade without extensive modification.
