Good To Know

Q: Is this piston kit suitable for a KTM 125 EXC that has been previously bored oversize? A: No, this is a standard bore kit (53.96mm) intended for engines with original cylinder dimensions; if the cylinder has been bored, you need a corresponding oversize piston.

Q: What is the difference between Size A, B, and C? A: These sizes represent small variations in piston diameter to allow for cylinder wear; always measure your cylinder and select the size that provides the correct clearance.

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