Nothing wrong with metzeler, there is very little room with the stock size rear as the 150 is a little wider than the stock Bridgestone I had. They wear nice as well, I have 12,000 miles on the back and I will probably get another 4-5000 miles out of it and I am hard on the throttle and carry heavy loads. I have run metz' on previous bikes with the same results.
