RZEOZU 420 Mini Bike Chain for Coleman CT200U & Predator 212 — Silver 420 Size, Heat‑Treated Steel with Master Links & Tools

RZEOZU's 420 mini bike chain is a heavy-duty replacement chain engineered to fit Coleman CT200U, Predator 212 and many other small off-road bikes, supplied with master links, a chain breaker and adjusters for a complete install.

This replacement 420 chain gives you a robust, silver-finished drive link engineered for small-displacement bikes and go-karts. Built from heat-treated high-strength steel, the chain balances durability with smooth operation while the included tools and extra links let you size and install it without a trip to the shop. Before installing, confirm your bike’s chain model (420) and count the links needed for proper tension and clearance.

Will this chain fit my Coleman CT200U or similar mini bike?

Yes—the RZEOZU 420 chain is designed to fit a broad range of small bikes that use 420-series chains. Compatibility covers multiple models from Coleman, Baja, Massimo, TrailMaster and others, but always verify the existing chain pitch and sizing on your machine.

• Fits Coleman CT200U, CT200U-EX, CT200U-EXR, BT200X and B200R models
• Compatible with Baja MB165 & MB200 (Heat, Mini Baja, Warrior)
• Works with Massimo MB165/MB200, TrailMaster MB200 and Axis/RT200 series
• Confirm chain number is 420 and consider sprocket tooth counts for exact fit

How durable and quiet is the RZEOZU 420 chain?

The chain is manufactured from heat-treated, high-strength steel to withstand repeated loads and resist wear. Its optimized link profile reduces friction and noise during operation without claiming specific lifespan figures—proper maintenance still extends service life.

• Heat-treated steel construction for improved tensile strength
• Optimized link design reduces friction and running noise
• Silver finish offers corrosion resistance and a clean look

What comes in the package and how does installation work?

RZEOZU supplies a comprehensive kit so you can size and fit the chain yourself: two chain lengths, multiple master links, a chain breaker tool and adjusters to set correct tension. The included components let you cut to length and reconnect the chain securely; follow standard chain-installation practices and torque specifications for your bike.

• 1 × 420 chain (42 links) and 1 × 420 chain (90 links) — choose or trim to fit
• 4 × 420 master links for secure reconnection
• 1 × chain breaker to remove or shorten chain links on-site
• 2 × 15 mm chain adjusters to set proper tension and alignment

What are the chain’s dimensions and important specs to check?

The RZEOZU chain follows standard 420-series sizing, so check your sprockets and existing chain for pitch and roller measurements before ordering. Matching these specs prevents premature wear and ensures smooth engagement with sprockets.

• Chain number: 420 (standard mini-bike size)
• Pitch: 1/2" (12.7 mm), roller width: 1/4" (6.35 mm)
• Roller diameter: 5/16" (approx. 7.94 mm)
• Available in 42-link and 90-link lengths to trim as required

Who this is for: Riders and small-vehicle owners who need a rugged, ready-to-fit replacement chain for mini bikes, pit bikes, go-karts or small off-road machines. The kit suits DIY mechanics who want a durable 420-series chain plus tools to shorten and install it, and shop owners who need a dependable aftermarket chain option that covers many popular models.
