S&S flywheel assemblies

S&S flywheel assemblies

S&S Cycle is now able to offer replacement three-piece flywheel assemblies for Harley-Davidson 120R engines, which have been designed to be stronger than stock to prevent flywheel shift.

The flywheel assemblies, which have been named by Cycle Source Magazine as its 2013 Performance Product of the Year, feature 4-5/8in stroke, stock for the 120R engine, and feature special 7.575in long S&S connecting rods. The flywheels are CNC machined from hardened 4140 steel forgings and the connecting rods are stronger than stock, with S&S Cycle stating that tests have shown them to have over 200 percent greater twist and bend yield strength.
The crankpin joint features the patent-pending S&S angled hole crankpin and its special drive plug to ensures full contact between the flywheel and crankpin across the length of the joint, and increased contact pressure.
S&S Cycle’s three-piece flywheel assemblies for Harley-Davidson 120R engines is available for both A and B style engines 2007and up, ’99-’06
A style, and ’00-’06 B style.
