Just for information purposes are the S&S flywheels forged? The web site says 114% stronger.
Looking more and more  at the S&S replacement crank for the 120r.

Yes they are forged, but the material they use is a key, critical, aspect to the inherent strength.
You can forge, say, 1018, and then you can forge 4130, 4140............HUGE difference.
