Looking for some advice on tyre selection. I am riding a Honda NT650 Bros. The bike is mainly used for weekend rides with fellow netriders, mainly twisties very little highway runs. I am experiencing high frequency vibrations through the handle bars, leaving my hands numb after a 300-400k ride. Close inspection of front tyre tred reveals the trailing edge lower then the leading edge, with minor separation deep in the main tred. So I am looking for a suitable replacement for the front tyre. The current tyre setup is Front Bridgestone Battlax BT39F 110/80-17 57H Rear Metzeler ME550 150/70-17 M/C 69V Any suggestions on bred and type of tyre for front?
