i just picked up my 2005 cbr 600 rr. i knew from the first time i saw the bike it needed new tires but i figured end of the year. i brought my buddy to pick the bike up and he said the tire had been used for a burn out. i didn't believe him. well today of course i go out side to admire my new bike and look at the bottom of the exhaust and there is some rubber. the tire is not that bad at all. but its got about a one inch flat spot all the way around the tire on the arch where the tire should be rounded. there is still plenty of tread on the tire and under that flat spot but when i corner will this pose a problem or can i ride the season with it?
