Zenoah 260/CY/QD HT CNC Lightened piston

These pistons have been lightened to 21 grams using a CNC machine making every piston the same. Lightened pistons (reducing reciprocating mass) allows higher RPM, longer engine life, and faster acceleration.

Note: The 260 piston has had the diameter turned down to avoid the seizure issue and the QD HT piston is the same piston but not turned down. (QH HT piston pictured)
