I'm not sure I understand what you are trying to accomplish with this post...but if you are trying to find the widest tire for your R1/R6 for purely aesthetic reasons, then look no further than the Dunlop 207 street compound.
This is typically the stock tire found on most of the Yamahas. They may look cool, but take it from me, and others on this board I'm sure, they handle like crap. The trade-off will be slow steering vs. better "looks."
Oh...the R1 has a 6" rear vs. 5.5" for the R6. I'm assuming you're not sure what will fit. Well...the 6" wheel will take up to a 200mm tire (I'm not sure why you would want to do this)...and the 5.5" will take up to a 190mm. Clearance problems shouldn't be an issue; however, the bike will handle like a Freightliner.
Either way...good luck.
