I just put the Q3+ on my L1 600 about a month ago. Went on vacation for two weeks so couldn't ride. So far they are scrubbing in nicely with just around 200 miles on them. The Dunlops that were on the bike when I got it last summer were squared of in the centers. The bike seemed to lean through turns fine below 50mph or so, but on the highway at 80 it was scary. The bike didn't want to lean over and crest those flat spots. What a difference with these new round Q3+ tires!!! I am running the tire pressures listed on my bike-. 36 psi front and 42 rear. I will follow this post as well, as I want as many miles out of these tires as possible!
