Isn't that the stock front tire size? Just wanted to clarify the differences and how it changed the handling for you.IRC NR770!
We switched to Dunlop TT93's and love them! Power Pures are very good tires as well. We went up a slightly bigger size to 100/90/12 in the front and 120/80/12 in the rear.
.Any clearance issues with the larger tires?
