YOXUFA 420 Motorcycle Chain 132 Links for Pit Dirt Bike

YOXUFA’s 420 motorcycle chain is a 132-link replacement kit (59" total) that includes a chain breaker and connectors for 50–212cc pit bikes, ATVs, mini bikes, go-karts, and 4-wheelers.

If you need a direct-fit 420-size drive chain for small-displacement dirt bikes, mini ATVs, or go-karts, this kit supplies a full-length 132-link chain plus the tools and connectors to size and install it yourself. The chain is designed for common Chinese and US small-engined recreational vehicles — think SSR, TaoTao, Coolster, Apollo, Roketa and similar models — and is sized to be shortened with the included breaker and master links for a clean, custom fit.

What vehicles and engines is this 420 chain compatible with?

This 420 chain is intended for 50cc through 212cc four-stroke small bikes and ATVs commonly used in pit, dirt, mini, and recreational powersports. It suits many popular models but always verify your current chain size before buying.

• Common matches: SSR, TaoTao, Coolster, Apollo, Baja, Kazuma, Roketa
• Fits bike families: CRF50/70/80, XR50/70/80-style mini pit bikes
• Also applicable for small ATVs, go-karts, mini bikes, and some 4-wheelers
• Designed for 50cc–212cc small-displacement four-stroke engines

How do I size and install the 132-link 420 chain?

The kit includes a 132-link (66 internal + 66 external) chain, a chain breaker tool, and ten 420 connector links so you can cut to length and finish the joint with a master link. Measure sprocket center-to-center and add tension allowance before removing links.

• Total length: 59" with 132 links, trim with the included chain breaker
• Link layout: 66 internal links + 66 external links for easy sizing
• Hardware included: 1 chain breaker tool and 10 connector links for secure joins
• Tip: confirm pitch (1/2") and roller width (1/4") match your sprockets

What are the chain's technical specifications and limits?

This chain follows standard 420 dimensions so it pairs with corresponding sprockets and fits most mini and small ATV drivetrains. The breaker tool supports sizes up to 530, making it useful beyond just this kit.

• Chain number: 420; pitch: 1/2" (12.7 mm)
• Roller width: 1/4"; roller diameter: 5/16"
• Sprocket thickness: approx. 0.227"; total chain length 59"
• Chain breaker compatibility: works for 420–530 chain sizes

What comes in the package and what should I check before ordering?

The package delivers the chain plus installation accessories, but you should inspect your bike’s current chain size, sprocket condition, and desired final length prior to purchase. Replacing a worn chain without addressing worn sprockets can shorten service life.

• Included: 1x 420 chain (132 links), 1x chain breaker tool, 10x 420 connector links
• Before buying: confirm your existing chain is 420 size and measure sprockets
• Consider replacing sprockets at the same time if teeth show wear or hooking
• Master link: can be added or removed depending on your preferred end joint

Who is this for: This YOXUFA 420 chain kit is aimed at DIY mechanics, hobby riders, and small-vehicle fleet owners who need a reliable, customizable replacement chain for pit bikes, mini ATVs, go-karts, and similar machines. If you maintain SSR, TaoTao, Coolster, Apollo, Roketa, Baja, Kazuma, or comparable small-displacement models and can measure and fit a chain, this kit gives you the chain length, connectors, and a breaker tool to complete the job at home.
