Belleone 420 Roller Chain Kit 132-Link Cut-to-Fit with Breaker Tool, Pre-Oiled 4000 lb Tensile

Belleone's 420 standard roller chain is a 132-link, pre-oiled drive chain with a 4000 lb tensile rating, supplied with a breaker tool and master links so you can cut it to the exact length your small-engine vehicle needs.

This 420 roller chain kit is built for compact powertrains — ATVs, dirt bikes, go-karts, mini bikes, and scooters — where a strong, serviceable chain matters more than brand-specific fit. It arrives factory-lubricated to prevent corrosion and includes multiple master links and a chain breaker that accepts 420–530 series chains, letting you trim and install the chain on-site without specialized shop equipment.

Will this chain fit my mini bike, scooter, or small ATV?

Yes. The chain is designed around the 420 specification (1/2" pitch) and works across a wide range of small-displacement machines. Confirm your sprocket pitch and roller width to ensure optimal compatibility.

• Fits common 50cc–212cc vehicles including many Honda CRF/XR models.
• Compatible with SSR, Coolster, TaoTao, Roketa, Coleman CT200U, and Baja MB200 families.
• Check sprocket pitch (1/2") and roller width (1/4") before installing.

How strong and durable is the Belleone 420 chain?

This chain is made from high-strength alloy steel and rated around 4000 pounds tensile strength, providing reliable load-handling for small engines and recreational use. The robust construction resists elongation and wear when paired with proper maintenance and correct sprockets.

• Alloy-steel links for improved fatigue resistance.
• 4000 lb approximate tensile strength for dependable power transfer.
• Factory pre-oiled to protect against rust during storage and shipping.

What tools and parts come with the kit, and how do I trim the chain?

The package includes a 132-link 420 chain, ten connector master links, and a chain breaker tool capable of handling 420–530 chains. Use the breaker to push out a link pin at the correct alignment, remove excess links, then attach a master link to complete the loop.

• Included chain breaker: suitable for 420–530 series chains; align the pin carefully to avoid tool damage.
• Ten master links provide backups and easier reassembly after cutting.
• Recommended: verify final length on the machine before removing excess links.

What are the exact chain dimensions and installation tips?

The chain follows the 420 standard: 1/2" pitch, 1/4" roller width, 5/16" roller diameter, and approximately 0.227" sprocket thickness. These measurements help you confirm compatibility with existing sprockets and chain guards.

• Chain number: 420; total supplied links: 132.
• Pitch: 1/2"; roller width: 1/4"; roller diameter: 5/16"; sprocket thickness: ~0.227".
• Expect the chain to be heavily oiled out of the box—clean excess oil only if needed before installation.

Who is this for? If you maintain or restore small-displacement motorcycles, pit bikes, go-karts, mini ATVs, or scooters and need a heavy-duty, cut-to-fit replacement chain, this Belleone 420 kit is a practical, workshop-ready option. It suits DIY mechanics who want the convenience of included master links and a breaker tool, or fleet owners and hobbyists who keep spare chains on hand for quick roadside replacements. Confirm your sprocket dimensions and follow standard safety procedures during cutting and installation.
