Athena S4C05400020C - Athena Cast-Lite Piston Kit For Honda CRF450R 2009-2016 Standard Size

Features: Manufactured by using advanced production technologies. Athena cast pistons, besides being lighter, represent the best solution in terms of price, performance and reliability. Using alloys with a high silicon content, it is possible to reduce the thermal expansion rate to which the piston is subjected during operation, ensuring a reduced piston-to-wall clearance and high performance over time. These pistons are treated with a transparent tin-coating or with a black Moly-coating. Sold complete with rings, wrist pin & circlips.
