## Vertex 24257100 Complete Piston - Forged, 69.46mm, 1.00mm Oversize This forged Vertex 24257100 piston, with a diameter of 69.46mm and an oversize of 1.00mm, is an excellent choice for motorcycles with a 250cm³ cylinder. Made from high-quality materials and precisely machined, it guarantees reliability and long service life. ### Strength and Reliability Forged Vertex pistons are known for their strength and resistance to extreme loads. The forging process forces the material to flow and shape around the die, creating the basic shape and structure of the piston. This makes the 24257100 piston exceptionally resistant to wear and ideal for demanding conditions. ### Optimal Compression The piston's 9.2:1 compression ratio ensures optimal engine performance. Combined with precise manufacturing, the Vertex piston contributes to improved motorcycle performance. ### Molybdenum Disulfide (MoS2) Coating Additionally, the 24257100 piston features a molybdenum disulfide (MoS2) coating, one of the most preferred dry lubricants. MoS2 is characterized by a low coefficient of friction, which minimizes piston and cylinder wear, contributes to smoother engine operation, and extends its lifespan. ### Precise Oversize The piston's 1.00mm oversize is the difference between the nominal piston diameter and the cylinder diameter in which it operates. This precise oversize guarantees a perfect fit and seal, resulting in optimal engine performance. ### Vertex Brand - Synonymous with Quality Vertex is a renowned manufacturer of motorcycle parts, known for the high quality of its products. By choosing the Vertex 24257100 piston, you are investing in proven quality and reliability.
