As for riding long distances, IMHO it all depends on if your riding a stock or tricked out Spyder. Just by looking at your pic on your sig line, I'm guessing you've not added much/anything to your RT yet:dontknow:
IMHO, Riding stock really puts alot of strain/pain on your back, butt and legs due to the limited range of motion that you have while ryding

Adding such things as a Cup-Holder, Utopia Backrest and Highway pegs can greatly increase your mobility while ryding & being able to stay hydrated (which is very important) and therefore your comfort level for being able to last much longer without getting yourself all tied up in knotts.
Teddy & I were able to do roughly 700 miles (stopping for fuel/potty breaks every 125 miles) a couple of weeks ago on our trip to SITA, and I was still ready for fun once we arrived at the campsite:yes: Adding those three mods makes an RT into a Barco-lounger on wheels:yes:
But you'll have to do whats comfortable for you and allot of that depends on you:shocked: Making sure to stay hydrated and stretching while on fuel stops are very important:thumbup:
Also, having a GPS is nice as well, not a must but more of a luxury, but sure is nice to be able to hit the "Find Nearest Fuel" when your out in the middle of nowhere and your "Low Fuel" light comes on:banghead:
Let me know if you'd like to get together when your here, cause you'll seriously be about 10 minutes south of us and we would be more than happy to show you some of the :yes:FUN:yes: roads to ryde:clap:
