I've used them on the rear of my DOHC CB750 Supersport. Also used Metzler Lasertec. I use 130- 90-18 on the rear, and ride fast on bitumen back roads. Happy with the grip but averaged less than 5,500 miles each. Now using Michelin Pilot Active, over 6,000 miles so far, plenty of tread left, good grip wet or dry.
