Since we are back on tires...
I run a Bridgestone Exedra Max on the rear, and Avon Cobra up front. Never had any issue with traction. Never had problems keeping up with anyone in the twisties, even 2up.
Original Metz rear only lasted 3500 miles, and front was so cupped by 4500 miles it had to be replaced.
That's about it for my attention span. Look a squirrel!
