My 2008 ZZR600 has Michelin Pilot Road 3s on it now.
I am considering going to Michelin Commander IIs next, since I only rarely ride in the rain and take corners at a more legal speed, for longer tire life instead of more grip.
The problem is that the closest sizes available for the Michelin Commander II are 140/75/17 front and 200/55/17 back, V speed rated to 149 mph.
Are these sizes close enough to the stock 120/70/17 front and 180/55/17 back sizes? Would the front fender need to be raised higher?
