Forged 89mm piston 12.7mm (1/2") shorter than standard, to be used with long connecting rods RTR1216L. This piston has an extra 12mm of crown material.

This extra material enables the machine shop to machine an intruder on top of the piston to increase the compression ratio where it would be undesirable to machine more material off the cylinder head.
