The amount of travel is less important than the quality and setup of the suspension.
My FZ6 was beating me up on rough, frost-heaved northern roads. Progresive fork springs and oil solved most of it. Proper adjustable cartridge forks rather than damper rods would be even better.
Simply having a lot of travel and softer spring rates isn't necessarily an improvement unless they are well damped, and the sag is set properly front and rear. It may feel less jarring on the straight sections with the cruise set, but if you get into some really good paved twisties and find out you're on a pogo stick, all is lost.
