Well I just got back from a 1000 mile trip in around 24 hours on a gen 4. I gotta say for being a fairly aggressive sitting bike I?m not very sore. Dunlop q3+ tires did very well too. If anyone is thinking of doing some long distance riding get a better seat and don?t leave your suspension set for the track.. the bumps in the highway will drive you insane after a while.
