I've seen many recommendations for this tire on this list and the Airheads list, so I bought one for my '74 R90S. I haven't installed it yet, and just today saw Tom Cutter's post on the Airheads list reporting his satisfaction with this tire on his R100(fakeS). He installed a 110/90 R18 on the rear. I bought a 120/90, since I'm currently running a Metzeler of that size. I have not had any problems with that larger size, although the tire is very close (about 3mm) to the swingarm on the right side. So I'm having second thoughts about my size choice. And since this Classic Attack is a radial, might it have some charactistics that would reduce its clearance to the swingarm?
Has anyone installed this tire on their RS, and what size did you choose?
