Good To Know

Q: Does this kit fit all KX250F years from 2012 to 2016? A: Yes, the listing covers that range, but confirm your exact year and engine code before ordering. Q: Is a shop press required to install it?

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
