LKSM 420 Motorcycle Chain 132-Link Gold — Heat-Treated Rollers, Corrosion-Resistant

LKSM 420 Motorcycle Chain Gold is a 132-link, gold-plated, high-tensile replacement chain designed to deliver longer life and reliable power transfer for 100cc–125cc mini motorcycles and similar small-engine vehicles.

This chain is built for riders who need a durable, corrosion-resistant drivetrain component for dirt bikes, pit bikes, ATVs, quads, go-karts and scooters. The gold finish gives corrosion protection and a premium look, while the 132-link length and heat-treated rollers provide smooth engagement with compatible sprockets. Before buying, confirm your vehicle’s required chain length and 420 pitch compatibility to ensure proper fit.

How durable is this LKSM 420 chain for everyday off-road use?

The LKSM chain uses high-tensile steel and a protective gold plating to resist rust and extend service life under normal riding conditions. Heat-treated rollers and reinforced pins reduce wear where the chain contacts sprockets, which keeps shifting and power transfer more consistent over time. Routine maintenance such as cleaning and lubrication will help maximize longevity.

• High-tensile steel construction for strength
• Gold-plated surface to limit corrosion
• Heat-treated rollers for reduced wear on sprockets
• Includes 10 chain connectors for secure installation

Will this 132-link chain fit my 100cc, 110cc or 125cc bike?

The chain’s 420 pitch and 132-link total make it compatible with many mini-bike and small-displacement motorcycle applications, but fit depends on your model’s required length and sprocket size. Measure the existing chain or check the manufacturer’s specification to verify 420 pitch and required link count. You can remove links or add included connectors to trim or join links during installation.

• 132 links — trim to match your bike’s exact length
• 420 standard pitch — confirm sprocket compatibility
• Includes 10 connectors for joining or shortening
• Works with many dirt bikes, pit bikes, ATVs, quads and go-karts

What maintenance does the LKSM gold chain need to perform well?

Like any motorcycle chain, periodic cleaning, inspection, and lubrication are essential to prevent premature wear and maintain smooth operation. Remove dirt and grit after muddy rides, inspect connectors and pins for damage, and apply chain lube at recommended intervals. Proper tensioning to your bike’s spec is also critical to avoid skipping or accelerated wear.

• Clean with a soft brush and appropriate degreaser
• Apply chain lubricant after cleaning and regularly in wet conditions
• Check and adjust chain tension per manufacturer guidelines
• Inspect connectors and replace if worn or damaged

Who is this for: The LKSM 420 Motorcycle Chain Gold best suits riders of small-displacement machines—100cc to 125cc dirt bikes, pit bikes, mini bikes, go-karts, and scooters—who want a rugged replacement chain with improved corrosion resistance and a polished look. If you need a 132-link 420-pitch chain that’s ready to be shortened and connected, and you perform regular maintenance, this chain provides a cost-effective option to restore drivetrain performance.
