Very interesting... has anyone compared the 17" tire off the older standards vs. the 18" from the 750/850? I wonder how much of a difference it would make?'79 XS11 F

Main problem with this swap is tire size availability is even worse than the existing 17" wheel...
Doing a search by the needed 130/90-18 size at MotorcycleSuperstore resulted in only four tires coming up; one each from Shinko, Bridgestone, Kenda, and IRC. I got no results at Jake Wilson. This will give you about a 1" gain in diameter, or about 4% more circumference; not very much.
Dropping down an aspect ratio size to a 130/80-18 will get you seven tires, but the change in aspect ratio means the tire is now the same diameter as the OEM replacement size 130/90-17, so there's no gain there. Same thing goes for using a 120/90-18; you get a lot more choices in tires, but no gain in diameter.
Even worse, these 'off' sizes don't have the specified load-carrying capability. The 'larger' 130/80-18 comes in at 660 lbs, or 10 lbs under the factory minimum of 670 (current 'stock' replacements are all at 690+). The 120 is even lower; only 640 lbs.Fast, Cheap, Reliable... Pick any two

Thanks, Steve. I was wondering about this but didn't have time to check the tire choices.Try your hardest to be the kind of person your dog thinks you are.
