I have a 2003 R6, and I replaced my stock Dunlops after they wore out with the m1's. I'm on my second set of them already, and I absolutely love them. Heat up quickly and get tons of grip for street tires. I've heard their wet traction isn't that great, but I haven't ever ridden hard enough while it's wet to really know. I'm going to keep putting them on until something better comes out.
Hope this helps.
