Meet GREHUA’s 420 mini bike chain, a purpose-built upgrade designed to handle the realities of hobby riding. The chain blends a robust alloy steel body with precise dimensions, aiming to deliver firm engagement with your sprockets and long-lasting performance across different mini bike setups.

Wide compatibility that fits your setup

• Predator engines: 196cc, 200cc, 212cc
• Mini bikes and DIY builds from Coleman, Baja, Massimo, TrailMaster
• Tomberlin Firehawk and Axi M200 variants

Whether you ride a CT200U, a Baja Warrior, or a Massimo MB200, this chain is designed to slot into common 420-standard systems with minimal fuss. The aim is to support reliable gear engagement as you ride through varying terrains and throttle needs.

Durability you can feel on the trail

• Heavy-duty alloy steel resists wear and corrosion
• Pre-stressed and pre-stretched for a consistently tight fit
• Built to withstand repeated use and maintain performance over time

In real-world riding, a tough chain helps keep the transmission aligned and the sprockets engaged, contributing to a confident feel through bumpy sections or sudden shifts. This quality translates into smoother stops and steadier acceleration, depending on your bike and riding style.

Smooth transmission, dependable power transfer

• Follows standard 420 specs: 1/2-inch pitch, 1/4-inch roller width, 5/16-inch roller diameter
• Non-slip design improves engagement with the sprockets for steady power delivery

The chain ships pre-lubricated and arrives with a complete tool kit, including 90 links, 10 master links, and a chain breaker. This setup makes setup accessible for hobbyists and beginners who want to tackle maintenance or replacements without needing special tools.

What’s included and how it helps

• Pre-lubricated chain for quicker install and immediate use
• 90 links and 10 master links for easy sizing and repair
• Chain breaker tool for disassembly and reassembly as needed
• Full tool kit to support straightforward installation and adjustments

Keep in mind that riding conditions and assembly accuracy influence results. This GREHUA chain offers a practical upgrade path that can support tighter engagement and potentially longer service life when paired with proper care and regular maintenance.
