DYC 420 Chain 132 Links with 5 Master Links and Chain

This kit supplies a ready-to-fit replacement chain for machines using 420 sprockets, so you can swap sprockets, restore worn drivetrains, or build a custom small-engine project without hunting for separate connectors or tools. Built to handle many common low-horsepower applications, the DYC 420 Chain balances strength, width tolerance, and field-serviceability.

How do I size and install the 132-link chain for my bike or go‑kart?

Start with the full 132 links and remove the excess using the included chain breaker tool until the chain matches your old chain length or the desired slack for your frame. Use a master link from the five included clips to join the chain, then check tension and alignment before final tightening.

• Begin at 132 links, remove links with the chain breaker for exact fit.
• Use one of five clip-style master links to connect the chain ends.
• Adjust rear axle for proper chain tension and inspect sprocket tooth engagement.
• Re-check fasteners and retorque after a short test ride.

Will this chain handle my engine’s power and riding conditions?

The DYC 420 chain is rated with a 4,000 lb tensile strength and a practical up-to-10 HP guideline, making it suitable for many 50cc–125cc bikes and common low-power mini bike or go-kart builds. It is designed for typical recreational use, trail riding, and general-purpose small-engine applications when used with the correct sprocket sizes.

• 4000 lb tensile rating for robust low-horsepower use.
• 16.2 mm maximum chain width to fit standard 420 sprocket spacing.
• Recommended for up to about 10 HP applications in regular riding conditions.
• Not intended for heavy-duty competition or extreme load environments.

Which vehicles and models commonly use this 420 chain kit?

This chain is widely used across many small-engine and recreational models that use 420 sprockets. It’s popular as a replacement or upgrade for brands and models such as Coleman, Baja, SSR, TaoTao, Coolster, Apollo, Kazuma, TrailMaster, Massimo, Axis Offroad, and Tao Motor platforms, among others.

• Common fit for mini bikes, pit bikes, dirt bikes, ATVs, and go-karts with 420 sprockets.
• Fits many 50cc, 70cc, 90cc, 110cc, 125cc applications and small-engine conversions.
• Useful for replacement sprocket swaps and custom driveline configurations.
• Always verify old chain size, link count, and sprocket type before installing.

What’s included and how does the chain breaker simplify field repairs?

The kit arrives with one 132-link 420 chain, five clip-style master links, and one chain breaker tool so you can size, connect, and repair without extra trips to the parts counter. The breaker removes pins cleanly for custom lengths and lets you reconnect quickly with a master link for roadside or garage fixes.

• Full 132-link 420 standard chain ready to cut to length.
• Five clip-style master links for spare connections or multiple installs.
• Compact chain breaker tool for pin removal and sizing on the bench or in the field.
• Designed to reduce extra shop work during installation and repairs.

Who is this for: The DYCTAHO DYC 420 Chain Kit is aimed at riders, hobbyists, mechanics, and DIY builders who maintain or modify small-engine machines that use 420 sprockets. If you own a mini bike, pit bike, dirt bike, ATV, or go-kart in the 50cc–125cc class (or certain low-horsepower conversions), and you want a reliable, serviceable chain that’s easy to size and join, this kit provides the chain, connectors, and a breaker tool in one package. Always confirm sprocket compatibility, chain pitch, and required horsepower tolerance before fitting to ensure safe operation.
