Description

The Vertex Pistons VTK22991A is a top-end piston kit designed as a cast replica for 2-stroke engines. It features a piston with a Molybdenum Disulphite coated skirt for faster break-in and increased life. The kit is made from a gravity-cast aluminum alloy with 18% silicone content.

This kit includes the piston, rings, pins, circlips, top-end gaskets, and wrist pin bearing. It is specifically designed for off-road riding and is compatible with the KTM 105 SX (2004-2011) and KTM 105 XC (2008-2009) models.
