FULL DESCRIPTION
Vertex Grade D 66.37mm Twin Ring Piston
The Vertex Grade D twin ring piston is a high-performance replacement component specifically engineered for two-stroke engines. Designed to meet the demanding requirements of off-road competition, this piston offers the ideal balance of durability, power, and precise tolerances to keep your engine running at its peak.
Vertex pistons are gravity cast from a premium aluminum alloy featuring an 18 percent silicon content. This advanced composition is vital for two-stroke engine efficiency, providing superior thermal stability and wear resistance throughout the engine's power band.
Key Features
- High Silicon Content: The 18 percent silicon alloy minimizes thermal expansion, allowing for tighter clearances between the piston and the cylinder wall. This ensures better compression and enhanced power delivery.
- Precision Engineering: By maintaining consistent geometry even at operating temperatures, these pistons reduce the risk of mechanical rattling and structural fatigue.
- Extended Service Life: The specific material properties of the alloy offer excellent wear characteristics, significantly prolonging the lifespan of the piston skirt and the overall top-end assembly.
- Twin Ring Design: Engineered to provide an optimal seal within the cylinder, the twin ring configuration promotes improved heat transfer and consistent combustion pressure.
Whether you are performing a routine top-end rebuild or restoring your engine to factory performance levels, Vertex pistons provide the reliability and consistency required for both casual riding and competitive racing.
