Good To Know

Q: When should the wrist pin bearing be replaced? A: It is normally replaced every time the piston is changed, since the bearing wears along with the top end. Reusing an old bearing on a new piston risks play and premature wear.

Q: Is this a direct fit for my EXC 250? A: It is designed for the EXC250 small end, but KTM changed dimensions across the 1990-2015 run, so confirm the pin diameter and bearing size for your year before ordering.

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