Oldfeller might have an answer for this one. Although it's a bit off Savage topic, it's still a darksider question.

I'm looking to pick up an '80 bare Goldwing 1100 with 44,000 miles on it for $800. Since I like the feel of that nice wide (by bike standards) radial on the back of my 650 I would like to go the same route on the back of the Wing if I decide to get it. Is there any info on 17" radials available? I know it has to be tall and skinny, like I used to be. Skinny that is.

When your "DARK-SIDDING" remember to keep your tire pressure up.   My last dark-ie  ripped a cord on the Dragon couse I let the pressure down to hug the curves better.    

But it was one of the quickest bikes of the day while it held !  

I'm running the Commander II now (S-40) and have about 10,000 miles on the rear now and its only half gone !   That's why I went Dark to begin with , I think Michelin got the message about long tire life.
My Sportster has a Commander II also ... 6,000 miles and still looks new-ish.
