S&S Cycle Pistons

Overview

S&S Cycle pistons are lightweight pistons manufactured from aluminum alloy. The aluminum is heat treated to strengthen it making the pistons stronger than stock motorcycle pistons. The strength of these pistons makes them the replacement parts of choice if the original ones are damaged or worn out. Pistons are important parts for any engine as they compress gases in the combustion chamber. They also transfer power through the connecting rods from the combustion chamber to the flywheels and crankshaft. The materials used to make these pistons are of high quality and this helps contain the heat in the combustion chamber thus reducing transfer of heat through the piston.
