Bigdon,
Mine is stock. Suspension set at 4 in the front and the rear. It handles like it's on rails.
Put it this way, it handles much better than my Goldwing ever did. It handles better than most cars, better than all trucks and better than most harley-type cruisers.
Just because ONE board member is willing to spend thousands of $$$ to make his RT handle like a Ferrari doesn't mean the rest of us need or have to. The RT is fine out of the box.
You're buying a touring machine, not a GP superbike. You're really over-thinking the whole thing. Buy it, fill it, ride it, repeat.
