RZEOZU 420 Mini Bike Chain for Coleman CT200U & Predator 212 — 42‑ and 90‑Link Kit, Heat‑Treated Steel Silver

RZEOZU 420 mini bike chain is a heavy-duty, heat-treated replacement chain designed to fit Coleman CT200U, Predator 212–compatible mini bikes and similar 420-drive models.

This replacement chain kit supplies two lengths of 420 chain, multiple master links, a chain breaker and adjusters so you can swap a worn or stretched drive chain quickly and get back on the trail. Built from high-strength steel with heat treatment and a silver finish, the chain is engineered to reduce noise and friction while delivering reliable tensile strength for typical mini-bike use. The package is aimed at owners who need a compatible, durable option for common 420-chain mini bike platforms.

Will this 420 chain fit my Coleman CT200U or Predator 212 mini bike?

Most CT200U-style mini bikes and many Predator 212 conversions that use the 420 chain spec will accept this RZEOZU chain. Confirm your current chain number and link count before installation to ensure compatibility.

• Chain specification: 420 (pitch 1/2", roller width 1/4", roller diameter 5/16").
• Included: one 42-link and one 90-link 420 chain for flexible sizing.
• Common compatible models: Coleman CT200U/CT200U-EX/CT200U-EXR, Baja MB165/MB200, Massimo MB200, TrailMaster MB200, Axis M200, RT200 and similar 420-drive mini bikes.
• Always match the chain model number stamped on your existing chain before ordering.

How does this chain improve durability and performance?

RZEOZU’s 420 chain is manufactured from high-strength steel and receives advanced heat treatment to increase tensile strength and wear resistance. The optimized link geometry helps the chain run smoother, lower noise and reduce friction for more efficient power transfer under normal riding conditions.

• Heat-treated steel construction increases fatigue resistance.
• Smoother engagement reduces drivetrain noise and heat buildup.
• Silver finish resists corrosion and keeps the chain looking clean.
• Designed for typical mini-bike loads, not for extreme competition tuning.

What tools and parts come with the chain to make installation easier?

The kit includes practical hardware so you can cut, size and join the chain without needing extra parts. A chain breaker lets you remove links to achieve the correct length and master links make reconnection fast and secure.

• 1 x 42-link 420 chain and 1 x 90-link 420 chain to choose the right length.
• 4 x 420 master links for secure reassembly.
• 1 x chain breaker tool to remove excess links on-site.
• 2 x 15 mm chain adjusters to help set proper tension.

How do I choose the correct link count and maintain this chain?

Measure from the center of one sprocket tooth around the drive to determine required length and compare to the provided link options. Regular lubrication and tension checks extend chain life and prevent premature wear.

• Measure existing chain or fit the longer 90-link then remove excess with the chain breaker.
• Set initial tension per your mini bike’s manual; recheck after the first ride.
• Lubricate roller and pin areas with chain oil periodically for best longevity.
• Replace sprockets that show heavy wear to avoid accelerating chain wear.

Who is this for: The RZEOZU 420 mini bike chain kit is suited for backyard mechanics, riders of CT200U-style mini bikes and small off-road conversions who want a ready-to-install, heavy-duty replacement. It’s ideal if you need flexibility in link length, the convenience of included master links and a breaker, and a durable chain built for routine recreational riding. If you plan on high-horsepower racing or heavily modified drivetrains, check specs with your builder to confirm suitability.
