I just got a L a week ago and it has a brand new AC 10 on the front. http://www.cyclegear.com/spgm.cfm?L1=&L2=&L3=&L4=&item=WES_87-9368_G&tier2=218 While it looks like a excellent tire for dirt, it seems like it will be dangerous for on the road if you really like to lean the bike through turns. It is DOT approved and Michelin states it will grip good on street but it can't possibly compare to a more street oreinted tire I would think? Since most of my riding will be on the street, I think I'm going to take it off but wanted to ask on here 1st, see if anyone has used one for a fair amount of street riding and hear their opinion on it. I did a search and didn't come up with much concerning the L model. Tons of info but mostly on the DRZ and it was a lot of trail talk, how great they are.
