KTM EXC 360 / 380 1996-2001 GRADE C 77.96mm

Precision Engineered Vertex Piston Grade C

The Vertex Grade C piston is engineered to deliver exceptional performance and reliability for high-output two-stroke engines. Designed with a 77.96mm bore size, this piston is manufactured using advanced low-expansion aluminum alloys charged with silicon, ensuring optimal thermal stability and durability under demanding riding conditions.

Vertex utilizes either precision gravity casting or hydraulic forging processes to create the piston blank. The material structure is further refined through a state-of-the-art automated heat treatment process, which includes solubilization and a specialized hot water quench to maximize strength and longevity.

Key Features

• Advanced Material Composition: Constructed from specialized aluminum alloys with precise silicon content to minimize expansion and maintain clearance.
• High-Tech Machining: Produced on CNC equipment utilizing diamond tooling to achieve exact tolerances and specific surface finishes tailored to engine performance.
• Dual-Layer Coating System: Features a phosphate coating for increased hardness and surface porosity, which acts as a superior base for the Molybdenum Bisulphite black coating.
• Reduced Friction: The specialized Molybdenum Bisulphite coating aids in the break-in process and significantly reduces internal cylinder friction during operation.
• Rigorous Quality Control: Every piston undergoes extensive manual and automated inspection to ensure it meets strict engineering specifications and quality standards.

By leveraging technology derived from elite motorsport applications, Vertex provides a piston that improves durability and efficiency. The enhanced coating adhesion ensures that the protective surface remains intact for longer, providing consistent performance throughout the service life of the component.
