Setting up suspension on heavy bikes is in some ways simpler than very light machines. Provided that the majority of that mass is sprung (not in the wheels and moving parts of the suspension) and also that it is not distributed away from the the CoG.
The force transferred into the chassis is a simple multiple of the mass of the unsprung parts and their acceleration (up and down). Those forces, being similar, will tend to upset a light bike much more so than a heavy bike. In theory at least ;-)
