LKSM 428H Motorcycle Chain 140-Link Gold Zinc Plated Kit with Chain Breaker — Fits 125–200cc Mini Bikes & Go-Karts

LKSM 428H Motorcycle Chain — a 140-link, gold zinc-plated drive chain kit that fits 125cc–200cc mini bikes, dirt bikes, go-karts and Chinese ATVs, and includes a chain breaker plus 10 connector links for installation and trimming.

This complete LKSM 428H chain kit is built for riders and DIY mechanics who need a durable, adjustable replacement chain for common small-displacement machines. The 428H-140 specification delivers a long length out of the box while the gold zinc finish improves corrosion resistance and gives a distinctive look. The kit is supplied with a handheld chain breaker and multiple connector links so you can size and join the chain without extra trips to the shop.

What machines is the LKSM 428H 140-link chain compatible with?

The chain is designed for 428H specification drives used on many 125cc, 150cc and 200cc mini bikes, dirt bikes, go-karts and Chinese-built ATVs. Its sizing and tensile characteristics match standard small-frame sprockets found on popular models from SSR, TaoTao, Coolster, Apollo, Baja and Kazuma.

• Fits engines and sprockets that take 428H chain profiles.
• Works with many Chinese-brand mini bikes and off-road karts.
• 140 links allow room to shorten for varied swingarm and sprocket setups.
• Includes connector links for secure joining to OEM-style plates.

How does the included chain breaker tool help during installation?

The small chain breaker in the kit lets you remove or add links without specialized shop equipment. It aligns with the pins of the 428H links and pushes them out cleanly so you can trim the chain to the correct length and then reassemble using the supplied connector links.

• Portable hand tool sized for 420–530 style chain pins, compatible with 428H adjustments.
• Enables on-vehicle sizing so you can test fit before final joining.
• Reduces need for professional disassembly services — ideal for roadside or garage work.
• Sturdy steel construction for repeated use during maintenance cycles.

What construction and protection features does this chain offer?

Manufactured from high-tensile steel, the LKSM 428H chain is plated with a gold zinc coating that resists surface corrosion and friction wear. The internal and external plate arrangement follows the H-series geometry for small-displacement powertrains, balancing strength with flexibility for smooth sprocket engagement.

• High-tensile steel core for load-bearing durability under typical mini-bike stresses.
• Gold zinc plating improves corrosion resistance and gives a clean finished appearance.
• H-series plate geometry engineered for consistent engagement with small sprockets.
• 140-link length (66 internal + 66 external) for versatile trimming and fitment.

How many parts are included in the kit and what's the trimming process?

The package contains one 428H chain (140 links), a chain breaker tool, and ten 428H connector links for joining the chain after sizing. To trim, measure required length on the bike, use the chain breaker to remove excess links, then insert connector links and secure them per standard chain joining procedure.

• Kit contents: 1x 428H-140 chain, 1x 420–530 chain breaker tool, 10x connector links.
• Trim by removing matched internal/external links to keep plate orientation correct.
• Use the breaker to push out the pin and reinsert connector link pins when joining.
• Check tension and alignment after installation before riding.

Who is this for: Riders, home mechanics and small-vehicle fleet owners who need a ready-to-fit, corrosion-resistant drive chain for mini bikes, small dirt bikes, go-karts and Chinese ATVs. The LKSM 428H kit is especially useful for those who want the convenience of an included chain breaker and multiple connector links so they can size and install the chain themselves without specialized tools.
