S&S Flywheels

15 products — part of all Flywheels

S&S flywheels give Harley-Davidson engine builders the precision-balanced rotating mass at the centre of a high-performance V-twin rebuild, engineered to tighter tolerances than the factory components they replace. The flywheel assembly is the fundamental structure of the Harley-Davidson engine — the two flywheel halves carry the crankpin and are pressed and trued to the exact runout specification that determines whether the engine runs smoothly or with vibration that transmits through the frame at every RPM. S&S have produced Harley-Davidson flywheel assemblies since the earliest days of the aftermarket performance industry, with a manufacturing precision that is used as a benchmark by engine builders looking to minimise vibration in high-compression or stroked V-twin builds. Flywheels are available in standard stroke configurations for direct replacement and in extended stroke dimensions for builders creating displacement upgrades from Shovelhead to Milwaukee-Eight applications. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries S&S flywheels alongside a full engine rebuild and performance components range. Browse the full S&S Flywheels range below.
