There are better tires, for much less money, available. For reviews by riders, I go here:
link. I ride on Pirelli MT66 Route tires, had them on three different bikes, only thing I will ride on. They run around $80/$120 for front/rear. Others on this site run on Shinko's. Check out some reviews, search on prices, and make an informed decision as to what you feel will work best/safest for you. Cheers!
