I usually try to stick with the original tyre size for my bikes and was happy with the Metzelers on my GSX750.
The GS1000G came with a 4.50V17 that I can't find anywhere and a conversion chart I found said it was closest to a 120/90-17. I was thinking of a Metzeler Tourance in that size. Looks almost liks a dual purpose tyre that I've seen on some adventure bikes. I like the dirt roads so could be good on both tar and dirt.
I think the Katana ran a similar size. What tyres are you running on you original wheels?
