I just brought my bike in for the 4k mile service. The tires on it are the origional tires that came with the bike. There is a huge flat spot in the center from the break in where I was too scared to lean into a turn (lots of fast in a straight line riding) so I kept it upright. My usual ride is through the canyons or around town. I am not racing or knee dragging so I dont know how aggressive a tire I really need. Any suggestions for a 2006 GSXR 600?
