Robbie, last month I put on a Yokohama Avid on the back of my VTX and have since logged probably close to 1000 miles. On my first ride I was dragging the boards and exceeded 95mph. On my second ride with the Darkside, I got caught an hour from home in a storm(10% chacnce of showers my a**). The tire handled the rain better than I could have imagined it, and the breaking power that can be applied to the rear now is tremendous.
It IS a litle different, but like many here have said, it's akin to riding a different bike and you DO get acclimated to the new feel very quickly. It does feel very stable, but I threw on a new front tire and dynabeads at the same time, so I cant accurately say how much the CT is a factor on how much the ride has improved.
Like me, I see that you have an R model. Getting the tire to bead with a tube on those spoked rims was an adventure to say the least! I blew up the first tire and had to modify the second one to get it to work. If I was doing it again, I would follow the sage advice given here and take the time to seal the rim. There are a few great write-ups here on how to do that. There are also some minor modifications recommended to get that tire to fit under the fender. Reverse the bolts holding the exhaust for more clearance. I also had to cut off about an inch of thread on 2 of the bolts for the sissy bar.
Good luck to you and ride safe.:mosh:
