Good To Know

Q: Do I need to bore my cylinder for this piston? A: Yes, a .020 oversize piston requires the cylinder to be bored and honed to the matching 72.50mm clearance before assembly.

Q: Should I replace both pistons at once? A: On a twin, it is good practice to rebuild both cylinders together so compression and wear stay balanced across the engine.

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