I'm looking to put a Shinko 705 on a GL1100 rear rim. Stock tire size is 130/90/17. My options are 130/90/17, 130/80/17, and 140/80/17 in the Shinko. I believe it's a 2.5" rim for the GL1100. I want a nice beefly look on the back, handling isn't the *most* important, but it is important. I'm going to be running a 120/90/17 up front on a GSXR750 rim. The 130/80 and 140/80 say 2.75 is the minimum recommended rim width, but I don't think .25" is going to make a huge difference... Thoughts? Charles.
