DYC 420 Chain 132 Links Cut-to-Fit w/Master Link + Chain

The DYC 420 Chain Kit is a full cut-to-fit drivetrain solution—132-link 420 chain with five master links, a chain breaker tool, and a cleaning brush for mini bikes, pit bikes, dirt bikes, ATVs and go karts.

If you're replacing a worn chain, changing gearing, or building a small-displacement ride, this kit gives you the parts and tools to size and maintain a 420-spec chain right away. The chain matches 420 dimensions (1/2" pitch, 1/4" roller width) so it meshes with standard 420 sprockets; including extra master links and a breaker tool simplifies field repairs and final trimming after fitment checks.

How do I know this chain will fit my mini bike or go kart?

Confirm your sprocket pitch and roller width match 420 specifications (1/2" pitch, 1/4" roller width). Many mini bikes, pit bikes, ATVs and go karts from brands like Coleman, Baja, SSR, TaoTao, Coolster, Apollo, Kazuma, TrailMaster, Massimo, Axis Offroad, and Tao Motor use 420 chains, but always verify before installation.

• Measure sprocket tooth pitch or compare to existing chain size.
• Check sprocket compatibility in owner manual or parts diagram.
• Use the included 132 links as starting length—trim to fit with the breaker tool.

What tools come in the kit and how do they simplify installation?

The kit includes five master links for quick connections, a manual chain breaker for removing links cleanly, and a chain brush for pre-lube cleaning. Together these components let you size the chain, connect it securely, and prepare rollers and plates for optimal lubrication and quieter operation.

• Master links allow fast on-vehicle joins and emergency repairs.
• Chain breaker tool ejects pins so you can remove excess links precisely.
• Chain brush removes grit so lubricant reaches rollers and pins effectively.

How should I care for the chain to extend its life?

Regular cleaning, correct tensioning, and periodic lubrication are the primary maintenance steps to keep a 420 chain running smoothly. Clean grit and metal debris with the supplied brush, set the recommended chain slack, and apply a suitable chain lube to reduce wear on pins and sprockets.

• Brush the chain before every lube to remove abrasive particles.
• Follow vehicle manufacturer torque and tension specifications when installing.
• Re-check master link security and pin retention after a short test ride.

Who is this kit for? Whether you're a weekend trail rider, a backyard mechanic, or a kart racer updating gearing, the DYC 420 Chain Kit is built for small-displacement drivetrains that require standard 420 sizing. It suits owners who want a ready-to-fit replacement plus basic tools for installation and upkeep—especially helpful for those working on Coleman, Baja, SSR, TaoTao, Coolster, Apollo, Kazuma, TrailMaster, Massimo, Axis Offroad, and Tao Motor machines. Measure your sprockets, cut to the proper link count, connect with a master link, keep the chain clean and lubricated, and the drivetrain will return consistent engagement and reliable service for everyday riding and racing use.
