HONDA CR 500 1985-2004 91.00mm TWIN RING REPLICA
Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18%, or 21% silicon content depending on the application. The pistons are made using gravity cast or hydraulic forging processes. The material structure is refined through a hi-tech heat treatment process using solubilization by quench in hot water. Machining is completed using the latest CNC machines and diamond tools to achieve specific surface finishes. Every Vertex piston undergoes rigorous manual and automatic quality control. Vertex pistons are coated with a special Molybdenum Bisulphite black coating for break-in and friction reduction. A newer Phosphate Coating is also available, offering increased hardness, light surface porosity, and superior adhesion qualities for extended coating durability. This is a twin ring replica piston with a 91.00mm bore size.

FULL DESCRIPTION
Vertex 91.00mm Twin Ring Replica Piston
Upgrade your engine performance with the Vertex Replica Piston, precision-engineered for riders who demand reliability and power. Designed for high-performance two-stroke applications, this 91.00mm twin ring piston offers an ideal balance of durability and efficiency, making it a perfect choice for engine rebuilds.
Vertex utilizes exotic Low-Ex (low expansion) aluminum alloys with high silicon content, ensuring exceptional thermal stability. Through a combination of gravity casting or hydraulic forging and advanced heat treatment processes, these pistons maintain structural integrity under extreme operating conditions.
Advanced Engineering and Durability
Every Vertex piston is manufactured using state-of-the-art CNC machinery and diamond-tipped tooling to achieve precise tolerances and specific surface finishes. To further enhance performance and longevity, these pistons feature sophisticated coating technology:
- Molybdenum Bisulphite Coating: A specialized black finish applied to the piston skirt to facilitate a smooth break-in process and reduce internal friction during engine operation.
- Phosphate Coating: Drawing on developments from Formula One, this coating increases surface hardness and provides light porosity. This improves the adhesion of the Molybdenum coating, effectively doubling its durability.
- Rigorous Quality Control: Each unit undergoes exhaustive manual and automatic inspections to ensure it meets the highest standards of quality and performance consistency.
Whether you are maintaining your bike for competitive racing or trail riding, the Vertex Twin Ring Replica Piston provides the professional-grade reliability needed to keep your engine running at its peak.
