Its for a Harley not really a sport tourer and not the tire most are putting on their bikes if you look at the threads.
I googled it and didn't see one anywhere near the right size, either.
I have the Harley bias-ply dunflop on mine now, I like it so far, it might wear
out quick (the OEM one did too)... I can't wait to get my ride-on in it and take
off the ugly stick-on weights they plastered all over my rim... it is not even
balanced well... I noticed this right away on the weekend-from-hell ride,
and have only ridden it to work a few times since...
Others have that pr4trail 120/70 on their bikes and like it.
