## Vertex 24259 Complete Piston - Forged, 86.46mm This forged Vertex 24259 piston with a diameter of 86.46mm is an excellent choice for motorcycles with a 420cm³ cylinder. Designed for maximum performance and durability, this piston will provide your engine with reliability and power for years to come. ### Strength and Reliability of a Forged Piston Vertex is a renowned manufacturer of motorcycle parts, known for the high quality of its products. Forged Vertex pistons are the strongest on the market, thanks to a special manufacturing process that forces the material to flow and shape, creating an exceptionally durable structure. The 24259 piston is no exception. Its forged construction guarantees resistance to high temperatures and loads, ensuring long-lasting and trouble-free engine operation. ### Optimal Compression The piston's 9.9:1 compression ratio has been precisely selected to ensure optimal engine performance. Combined with the forged construction, this piston delivers excellent performance and responsiveness. ### Molybdenum Disulfide (MoS2) Coating An additional advantage of the Vertex 24259 piston is the molybdenum disulfide (MoS2) coating. MoS2 is one of the best dry lubricants, known for its durability and low coefficient of friction. This coating minimizes friction between the piston and cylinder, reducing wear and extending engine life. This allows you to enjoy smooth and efficient engine operation for a long time. ### Summary The Vertex 24259 complete piston is an investment in the performance and longevity of your engine. The durable, forged construction, optimal compression, and MoS2 coating make this piston the ideal choice for demanding motorcyclists.
