The Story
This Wossner piston kit with an 84mm bore is a standard replacement for Kawasaki ZX14 models from 2006 to 2009, including Pro Series configurations. Forged in Germany, the pistons are engineered for high strength and optimal heat dissipation. Featuring a high-compression flat top design, the elliptical profile ensures even load distribution and reduces the risk of piston collapse during high-performance use.
Features
