KAMIER 428 Drive Chain 102-Link Kit for 50–125cc Bikes & ATVs — Includes Chain Breaker & Master Links

KAMIER 428 drive chain is a 102-link heavy-duty replacement chain kit that includes a chain breaker and extra master links for 50cc–125cc pit bikes, ATVs, quads and go-karts.

This replacement chain kit is designed to fit a wide range of small-displacement four-stroke machines—50cc through 125cc—commonly found on CT90/CT110-style bikes, TaoTao, Apollo, Coolster, Vitacci, TrailMaster and many Chinese-made pit bikes and ATVs. The kit arrives ready to size: a 428 pitch chain with 102 links, a handy chain breaker tool, and spare master links so you can shorten or lengthen the chain to match your sprockets. It’s intended as a practical, all-in-one service part for routine maintenance, repair after wear, or a drivetrain upgrade when you need a reliable replacement chain that works with matching 428 sprockets.

Will this chain fit my 50cc–125cc bike or ATV?

The KAMIER 428 chain fits machines that use a 428 pitch front and rear sprocket; it does not fit systems using a 420 rear sprocket. Many common models from TaoTao, Apollo, TrailMaster, Vitacci and similar manufacturers use 428 chains, but always verify your sprocket pitch before ordering.

• Size: 428 pitch, 102 total links (51 internal + 51 external)
• Compatible with many CT90/CT110-style bikes and 50–125cc four-stroke units
• Not compatible with 420 rear sprockets

How easy is it to install and size this chain?

The kit includes a chain breaker tool and ten master links so you can cut the chain to length and reconnect it without specialized shop machines. Typical installation requires basic hand tools, the included breaker, and routine alignment and tensioning checks after fitting.

• Chain breaker tool included for cutting and pin removal
• 10 master links supplied for flexible sizing and secure joining
• Adjustable link count lets you fit different swingarm lengths and sprocket offsets

What durability and maintenance should I expect?

This heavy-duty replacement chain is built for general trail, pit, and utility use rather than high-performance racing. Regular lubrication, tension checks, and sprocket inspection will maximize wear life; replacing sprockets with the chain is recommended if they show heavy wear.

• Designed for everyday off-road and utility riding conditions
• Routine chain lube and tensioning increases service life
• Replace worn sprockets to prevent premature chain wear

What comes in the box and what should I check after delivery?

The package includes the 428 chain (102 links), a chain breaker tool, and multiple master links so you can adapt the chain length on the workbench. After unpacking, confirm the chain pitch matches your sprockets and make any link adjustments before final installation.

• Contents: 1 x 428 chain (102 links), 1 x chain breaker tool, 10 x master links
• Inspect chain pitch and link count before cutting or fitting
• Test final tension and alignment after installation

Who is this for: This KAMIER 428 102-link chain kit is ideal for riders, mechanics and small-shop owners maintaining or repairing 50cc–125cc four-stroke dirt bikes, quads, ATVs and go-karts that use 428 sprockets. Choose this kit if you want a complete, ready-to-size replacement with tools and spare master links included—especially useful for field repairs, backyard mechanics, and fleet maintenance of entry-level off-road machines.
