Good To Know

Q: Does this kit include everything needed for a full rebuild? A: It bundles a standard piston, crankshaft, and gasket set, though bearings and other wear items may still need separate replacement depending on engine condition.

Q: Is the 66.40mm bore size standard for this engine? A: Yes, 66.40mm corresponds to the stock cylinder bore for the KX250, so no overboring is required when using this piston.

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