Athena 05-07 Suzuki RM-Z 450 95.46 4T Forged Racing Piston

The Athena S4F09550004A is a forged racing piston designed for OE cylinders with a 95.46mm bore diameter. It is constructed from a special high-performance aluminum alloy with high silicon content for enhanced reliability, resistance, and performance. The piston features a smooth profile for optimal flow and flame propagation, and some skirts are treated with a molybdenum disulfide coating to reduce friction. The included piston rings, produced in Japan with wear-resistant coatings, further minimize friction and increase durability. This kit includes the piston, pin, circlips, and rings, all of which are replaceable.
