DYCTAHO DYC 420 Gold Chain 132-Link Kit with 5 Master Links & Chain Breaker — 4000 lb Tensile

The DYCTAHO DYC 420 Gold Chain kit is a complete replacement chain set for mini bikes, pit bikes, ATVs and go-karts using 420 sprockets, including a 132-link gold chain, five master links, and a chain breaker tool for sizing and installation.

Upgrade or replace your small-engine drivetrain with a ready-to-fit 420 standard chain engineered for common 50cc–125cc and many low-horsepower mini bike and go-kart setups. This kit delivers a 132-link chain with a decorative gold finish, a small tool for removing links, and extra master links so you can cut and reconnect to the exact length required for your sprocket configuration. The chain is rated with a 4000 lb tensile strength and 16.2 mm max width to match 420 sprocket systems found across many popular entry-level powersports models.

How do I size this chain for my bike or kart?

Measure the required chain length by wrapping your old chain around the sprockets or by measuring center-to-center distance between the axle and countershaft. Use the included chain breaker tool to remove excess links and test fit with a master link; re-check the tension and alignment before trimming further.

• Start with all 132 links — trim only as needed with the breaker tool.
• Fit a master link, then rotate the drivetrain to check tension.
• Finalize length when proper slack matches your vehicle’s spec.

What maintenance keeps the gold finish and chain life longer?

Regular cleaning to remove dirt and grit, routine lubrication, and consistent tension checks prevent premature wear and help the gold finish remain cleaner for longer. Avoid harsh chemicals that strip coatings; use chain-specific cleaners and lubricants recommended for small drive chains.

• Clean with a soft brush and chain cleaner — avoid wire brushes.
• Lubricate after cleaning and after wet rides to reduce corrosion risk.
• Inspect for stiff links, rust, and wear; replace if damaged.

Can this chain handle my vehicle’s power and sprocket type?

The DYC 420 chain is sized to the 420 standard and is suitable for many 50cc–125cc bikes and many low-horsepower 196cc–212cc mini bike and go-kart builds using 420 sprockets. It carries a 4000 lb tensile strength and up to a 10 HP usage guideline — always verify your vehicle’s sprocket pitch, recommended chain size, and power output before installation.

• Matches 420 pitch sprockets (check sprocket teeth and spacing).
• Rated ~4000 lb tensile strength; suitable for many low-HP applications.
• Common fit for entry-level Coleman, TaoTao, Coolster style models.

How do the included master links and breaker tool simplify installation?

Five master links give spares for installation and future repairs, and the compact chain breaker tool lets you remove individual links without needing a full workshop. Together they make on-vehicle sizing and field repairs faster and reduce the need to order separate parts to complete a fitment.

• Five master links allow several reconnections or backups.
• Chain breaker tool removes pins cleanly for precise length adjustment.
• Useful for on-trail or garage installation without specialty tools.

Who is this for: The DYCTAHO DYC 420 Gold Chain kit is aimed at hobbyists and small-engine mechanics replacing or upgrading 420 drive chains on mini bikes, pit bikes, ATVs and go-karts. It suits owners who want a complete, ready-to-fit package (chain, spare master links, and breaker tool) with an upgraded gold appearance, and who understand how to verify sprocket pitch, link count and tension for safe operation.
