The flywheels are the heart of any performance engine and S&S Cycle has been perfecting the art for over six decades. Stronger, more durable, and trued to a spec others can only dream of. Available with tapered connecting rods for stock style pistons or with full width connecting rods for S&S performance pistons. Three piece design with integral main shafts made from 4140 steel.
