KTM SX 144 / 150 2007-2015 GRADE D 55.98mm

Vertex High-Performance Piston - Grade D 55.98mm

Enhance the performance and reliability of your engine with this premium Vertex piston. Engineered for durability and precision, Vertex pistons are trusted by riders and mechanics worldwide for their ability to withstand demanding racing conditions while maintaining consistent power output.

Vertex pistons are manufactured using exotic Low-Ex (low expansion) aluminium alloys, specifically chosen for their high silicon content. This advanced material composition ensures superior dimensional stability and heat resistance. The manufacturing process utilizes either a gravity cast or hydraulic forging method, followed by a state-of-the-art heat treatment process that refines the material structure to ensure maximum strength and longevity.

Key Features:

• Precision Engineering: Machined using the latest CNC technology and diamond-tipped tools to achieve exact tolerances and specific surface finishes for optimal performance.
• Advanced Coatings: Features a Molybdenum Bisulphite black coating to assist with the break-in process and significantly reduce friction during operation.
• Enhanced Durability: Incorporates a phosphate coating derived from Formula One technology. This provides a slight increase in hardness and improved surface porosity, ensuring superior adhesion of the Molybdenum coating and doubling its operational lifespan.
• Quality Assured: Every piston undergoes a rigorous manual and automatic quality control inspection to ensure it meets the highest industry standards for reliability.

Designed for those who demand the best from their machine, this Grade D 55.98mm piston offers the perfect combination of structural integrity, reduced friction, and long-term durability. Whether you are performing a top-end rebuild or a full engine refresh, Vertex provides the professional-grade components required to keep your engine running at its peak.
