I put them on this spring, only have about 1000 miles on them but I like them so far. I had the Traxxion AK20's rebuilt this winter and I'm running 13" Bitubo's with the Baker + 1 oil pan that came with the True Track system. Lately I have been able to increase my lean angle to the point of grinding the True Track swivel on the pan. I have always scraped floor boards and the arms to the floor boards when I'm riding solo. I did add 2 more pounds per the manuals recommendation. Rides a little harder but I don't want to deal with tire cupping. They are somewhat smaller, my Wheeldock had to be shimmed for the front, the Dunlops use to fit real tight. I hope these tires work out for us as I would love to never put a Dunlop on anything. Right now the bike has never handled as well in tight corners so at this point I'm satisfied.
