Manufactured by using advanced production technologiesAthena cast pistons, besides being lighter, represent the best solution in terms of price, performance and reliabilityUsing 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 timeThese pistons are treated with a transparent tin-coating or with a black Moly-coatingSold complete with rings, wrist pin & circlips
