FITMENT NOTE:
This is a 428 sprocket conversion - it does not fit on 420 chain which is standard for Kawasaki KX80/100 models

NOTE:
We display every sprocket that fits the machine selected. Be sure the tooth count matches your application for OEM sizing. When changing sprocket sizes be sure to check clearances and chain length. If you need the standard tooth size information or chain size and length, call us toll-free 800-969-7504

Anytime you use other than the standard front/rear sprocket sizes, clearance must be checked.

When converting to a smaller chain size, especially for racing, be sure to use the highest-grade O-ring chain available (Heavy-duty non-O-ring acceptable for drag racing.)
