## Vertex REPLICA 22951A Complete Piston - 89.96mm, Forged, for 400cc Cylinder This forged Vertex REPLICA 22951A piston with a diameter of 89.96mm is the ideal choice for motorcycles with a 400cc cylinder. Designed for maximum performance and durability, this piston offers unparalleled quality and precision, characteristic of the Vertex brand. ### Strength and Reliability of a Forged Piston Forged pistons, such as the Vertex REPLICA 22951A, are considered the strongest on the market. The forging process forces the material to flow and form around the die, creating an exceptionally strong and wear-resistant structure. This guarantees long life and reliability even in the most demanding conditions. ### Optimal Compression and Performance The 11.3:1 compression ratio ensures optimal combustion of the fuel-air mixture, which translates into increased power and torque. The Vertex REPLICA 22951A piston is an excellent choice for those who expect the highest performance from their motorcycle. ### MoS2 Coating for Reduced Friction Additionally, the Vertex REPLICA 22951A piston is coated with molybdenum disulfide (MoS2). MoS2 is one of the most effective dry lubricants, known for its durability and low coefficient of friction. This coating minimizes friction between the piston and cylinder, contributing to extended engine life and improved efficiency. ### A Selection - Guarantee of Precision The Vertex REPLICA 22951A piston has an A selection, which indicates the highest precision of workmanship and compliance with stringent quality standards. By choosing this piston, you can be sure that you are receiving a top-class product. ### Summary of Benefits: * Forged for maximum strength * 89.96mm diameter for 400cc cylinder * 11.3:1 compression for optimal performance * MoS2 coating for reduced friction * A Selection - guarantee of precision * Vertex brand - synonymous with quality
