What are the differences between the Twin-Cam engines mounted in Touring, Softail and Dyna models?
As I understand the Softail models have a B engine which has counter-balancers since the engine is mounted rigidly in the frame. But is there any significant difference between a Dyna engine and a Touring engine?
I am asking because - when looking through Harley-Davidson catalogs - the engine stage kits and upgrades that are stated to fit Touring models do not fit Dyna models...

Twin cooling option for some touring models

Two biggest differences in know of between touring and dynamic.
