- ALL Chinese ATVs use a standard numbered chain
- #420 chain used on ATVs usually with a 7 inch rear wheel or smaller
- #428 chain used on ATVs usually with a 8 inch rear wheel or larger
- #428H is sometime used on 110 Utility Class ATVs
- #530 chain is used on all Kazuma 110c, 150cc, 250cc
In our experience the other numbers in the chart are rarely used on the Chinese ATVs. Some of the front drive sprockets will have numbers on them which identify exactly what chain number is used.
The #428 and #428H are interchangeable and will run on the same sprockets. The H means heavy duty and the chain has thicker heavier side plates. Other sizes will not interchange with drive sprockets
The Kazuma ATVs under 110cc but including the Kazuma Viper Dirt Bike all use the #428 chain.
Some early day Redcat ATVs are actually Kazuma made and use the Kazuma sizes above.
Chains can always be measured to identify the size. Always keep a few masterlinks on hand as spares. A lost masterlink can ruin a kids weekend of riding fun. Keep chain masterlinks on hand or carry extras while trail riding. The above information is only intended to be a reference to help you identify and measure your chain. Many other variations of Chinese ATVs are wide-spread ----MEASURE YOURS before ordering Click this link for more chain listings.
