DYCTAHO 420 Drive Chain Kit 132-Link with 5 Master Links & Breaker Tool — 4,000 lb Tensile, 16.2 mm Width

DYCTAHO DYC 420 Chain Kit is a ready-to-fit 132-link 420 drive chain bundle that includes five master links and a chain breaker tool for quick sizing and installation on mini bikes, go-karts, ATVs and other 420-sprocket small-engine vehicles.

This complete replacement chain package is built to make drivetrain swaps and custom small-engine projects faster and more reliable. The 132-link 420 standard chain arrives long so you can cut it to the exact length you need using the included chain breaker tool, and the five clip-style master links simplify reassembly and roadside repairs. With a 4,000 lb tensile rating and a 16.2 mm maximum width, the chain is aimed at low-horsepower applications commonly found on 50cc–125cc bikes and many mini bike or go-kart builds.

How do I size and install the DYC 420 chain?

Start with the full 132-link length, loop the chain around your front and rear sprockets, and mark the excess links to remove. Use the included chain breaker tool to punch the pins out cleanly; finish by joining with a master link clipped in place. Installation is straightforward for anyone comfortable with basic drivetrain work.

• Use the chain breaker to remove excess links to match wheelbase and sprocket teeth.
• Align chain on both sprockets before cutting to ensure correct tension and fit.
• Secure with one of the five included clip master links; keep extras for spares.
• Check chain tension and alignment after a short test ride and re-torque components.

What vehicles and engines are compatible with this chain kit?

This 420-standard chain is designed for vehicles that use 420 sprockets and is commonly fitted to mini bikes, pit bikes, ATVs, and many go-kart and small-engine platforms. It suits low-horsepower drivetrains up to about 10 HP and is popular among common brands and models in the 50cc–125cc range.

• Commonly used on mini bikes, pit bikes, and small ATVs with 420 sprockets.
• Fits many 50cc, 70cc, 90cc, 110cc, and 125cc small-engine applications.
• Often chosen for Coleman, Baja, SSR, TaoTao, Coolster, Apollo, Kazuma, and Massimo models.
• Also useful in custom go-kart and mini bike builds using 420 sprockets.

What durability and performance should I expect from the 420 chain?

The chain is built to a 4,000 lb tensile strength specification with a 16.2 mm maximum width and a practical rating for low-horsepower use. That balance of strength and size makes it suitable for reliable everyday riding, trail use, and general-purpose off-road recreation without the added weight of heavy-duty motorcycle chains.

• Rated at approximately 4,000 lbs tensile strength for dependable small-engine duty.
• 16.2 mm max chain width matches standard 420 sprocket spacing and profiles.
• Recommended for applications up to around 10 HP—ideal for mini bikes and go-karts.
