Thanks all. Never heard that term "mullet" for tires but I assume you mean more aggressive dirt tire on the front and longer lasting dual-sport tire on the back?
I've tried MT-21's and Dunlop 606 before. They just don't seem to offer enough grip (on front) for the kind of riding my buddies do. It's kind of an Enduro or Harescrambles, almost race pace type of riding on trails. I'm wondering if I could run a more dirt oriented tire on the front (XCMS Pirelli, Michelin S-12, Dunlop Geomax 51) and then run a little less agressive dirt tire on the back: MT - 21 etc maybe? For those who ride the more race oriented dirtbikes have you tried something like this?
Or maybe i need to go with more dual sport, longer lasting tires and just become a better rider in the slop!
thanks for your thoughts all!
