Belleone 420 Motorcycle Roller Chain Kit — 132-Link 420 Alloy Steel, Includes Chain Breaker & 10 Master Links

Belleone 420 Motorcycle Chain is a heavy‑duty 132‑link 420 roller chain kit that includes a chain breaker and ten master links to fit 50–125cc dirt bikes, ATVs, go‑karts, scooters and mini bikes.

This complete chain package gives you a durable, serviceable replacement designed for small‑displacement motorcycles and off‑road machines. Crafted from alloy steel, the 420 standard roller chain is built for frequent use and straightforward installation: the supplied master links let you size the chain to your sprockets, and the included chain breaker lets you shorten or separate links without extra tools. The kit ships pre‑lubricated for corrosion protection during transit.

How tough is this 420 chain for everyday riding?

The Belleone 420 chain uses alloy‑steel construction and standard roller chain dimensions to deliver reliable wear resistance for small engines and off‑road use. It's not a sealed O‑ring chain, but its heavy‑duty plates and rollers provide extended service life when cleaned and lubricated regularly.

• Alloy steel for strength and long durability.
• 132 links to cover common rear center distances; removable links for custom fit.
• Pitch 1/2", roller width 1/4", roller diameter 5/16"—meets 420 standards.
• Pre‑oiled to resist rust during shipping.

Which bikes and ATVs will this chain fit?

This chain is sized and specified for small displacement machines that take a 420 chain. It’s commonly compatible with 50cc through 125cc pit bikes, scooters, mini bikes, quad ATVs and go‑karts that list 420 chain dimensions.

• Fits many 50/70/90/110/125cc pit and dirt bikes.
• Works with go‑karts, mini bikes, scooters and small ATVs/quads.
• Listed compatibilities include SSR, Coolster, TaoTao, Roketa and similar models.
• Master links let you adapt length for different sprocket setups.

What tools and parts are included for installation?

The kit arrives with everything you need to size and join the chain without hunting for separate items: a chain breaker for splitting links, and ten connector master links so you can assemble or repair the chain quickly. You may still need basic hand tools like wrenches and a torque wrench for sprocket and axle work.

• One 420 roller chain, 132 links, pre‑oiled.
• One compact chain breaker suitable for 420–530 chains.
• Ten master connector links for joining or repairing the chain.
• Recommended: basic wrench set and chain lubricant for final setup.

How should I maintain and size this chain for best life?

Correct tensioning, regular cleaning and lubrication extend chain life more than any single spec. After installation, adjust chain sag to the manufacturer’s recommendation, lubricate frequently if ridden in wet or dusty conditions, and inspect for stiff links or excessive wear.

• Use the chain breaker to remove excess links and set correct tension.
• Lubricate after cleaning and every few rides in harsh conditions.
• Replace connector links periodically if you notice elongation or wear.
• Inspect sprockets—worn sprockets accelerate chain wear.

Choose this kit if you want a full hardware package—chain, chain breaker and multiple master links—that lets you size, install and repair a 420 chain without sourcing extra parts.
