I don't know what the majority uses,just what I like most. I have used Bridgestones in the past,but didn't like the way the front wore(010) I've used a set of Michilan (Piolot Powers I think,its been a few yrs.),they were alright,wore out around 2800miles.
I've used up many Dunlop 207s,gave me good stick @ the track and the twisties,but now using 208 Qualifiers. As far as I'm concered,they're top shelf for all around road /track,and desent in the wet too. Also have a set of 208 GPs(track only) that were the best I've used on the track (for awhile) but after a few track days and heat cycles they get real greasy.
The tires that I've been using most for the last few yrs on the Bandit are the Conti's. They are more reasonably priced,and I can not find any complaints. I've used the Sport Attack and got around 3K(maybe a bit short off)out of them, then switched to the Road Attacks for more milage and they still stick pretty good. Done track days with them (while new)with good stick, good in the wet, I like the way the bike handles with them, good all around tire with a desent price tag. Get a little over 3 K out of the back (2 fronts to 1 back)
On the track this year,I'd like a set of maybe 209GPs,or a set of slicks,maybe a set of rains. My 1st choice of tire will be what ever set I get spocered with! If my wife doesn't veto my racing this year,I can get a couple sets for free from Cycle City of Erie,and KK Speed & Sport of Erie(my home shop). Dan
