Good To Know

Q: Does this kit include a cylinder? A: No, this is a top-end rebuild kit only and does not include the cylinder or cylinder head; it contains the piston assembly and gaskets for reusing the existing cylinder.

Q: Is the piston from Namura or OEM? A: This is a Namura replacement piston, not an OEM Suzuki part; it is manufactured to match OEM dimensions and performance.

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