Good To Know
Q: Is this kit a direct drop-in fit? A: The kit is designed as a standard bore size C (76.8mm) for the Honda CRF250R, but cylinder wear and condition may require light honing or measurement before installation to confirm clearance.
Q: Does this kit include everything needed for top-end work? A: The kit includes the piston, ring set, wrist pin, and circlips; you will still need a new cylinder gasket set and possibly a cylinder re-hone or bore check depending on cylinder condition.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
