Why put your bike engine back together with stock parts—when you can upgrade with one of the S&S Cycle flywheel assemblies? These 3-piece units are forged and heat-treated from 4140 steel, making them harder and stronger than stock. They're precision-machined to be truer (for less vibration), and are assembled with integral mainshafts and lightweight connecting rod forgings. Stock flywheels shift out of true under heavy loads; improve your motorcycle with an S&S Cycle flywheel assembly.
