PISTON KIT 06-09 ZX14 KAW 87, WOSSNER K8785D300-4 ROAD, KAWASAKI

This Wossner piston kit with an 87mm bore is an oversized (+3mm) high-compression flat top replacement for Kawasaki ZX14 models from 2006 to 2009, including Pro Series variants. Manufactured in Germany, these forged pistons are built to withstand high-performance demands, offering excellent thermal management and structural stability. The elliptical profile allows for even pressure distribution, minimising localised stress and preventing piston collapse under heat and load.
