Actually, I'm in need of almost the same info. I need a new rear tire for my '02 500R.
I also want to stay with a stock size rear for right now. Here's what I found I liked:
Metzeler ME 550
Bridgestone BT45
Pirelli Sport Demon
Michelin Macadam 50
I have less than two months before my inspections up and my rear won't pass.
Any Suggestions for which one to get? I kinda like the looks of the Bridgestone BT45.
