Running the 55 Avon on the rear here. I wanted to correct the speedo a bit, and the taller tire makes the profile a bit rounder too. I tried a dual compound heavy sport bike tire in front. Don't Do that! It handled great to about 1L miles, then wore the sides out and left the center section stupid tall. It's all but dangerous to ride. Single compound for a heavy bike on the front ONLY!
On the rear Avaon I've been happy. A bit more stick that the stock tire and it does drop cruise RPM a bit AND help the damn speedo. Which is just stupid off from the factory. Handled a tiny better, but I didn't see anything shocking there. I'm 6'1 so the extra height means nothing to me....
I'm about to grab an Avon front (love their warranty) or the Shinko front. Guess we'll see. I hear lots of love for the Shinko, but a matched brand seem more logical. Not sure I care. Lord knows the Shinko is a lot cheaper.
Anybody know which is the softer compound? I'd like to get 4K miles out of it, but otherwise grip is king on the front...
