The Vertex OE Replica piston kit is engineered to deliver true OEM-spec performance for the KTM 50 SX two-stroke engine.

Installing a Vertex OE Replica piston kit in your KTM 50 SX ensures consistent power delivery, reliable compression, and durability designed for high-revving youth motocross engines.

Each Vertex OE Replica piston kit is gravity-cast from a lightweight aluminum alloy containing 18% silicone and heat-treated using a T-5 hardening and tempering cycle for strength and thermal stability. A proprietary Molybdenum Disulphide (MOS2) skirt coating reduces friction, promotes faster break-in, and minimizes wear during race and practice conditions.
