Every tyre is designed for a specific rim width. Two tyres both 90/90-17 can form a very different side profile/diameter if its meant to fit a different sized rim. I'll give you an example, when I was using my bike's stock Zapper FS front tyre, the speedo reading was 88 Kmph @ 6K RPM in top gear. Then I changed my front tyre to a 90/90-17 IRC Wildflare and my speedo then showed 86 Kmph @ 6K RPM. The IRC was meant to be used on a bike with a wider rim, on my thinner rim it formed a taller aspect ratio and thus the under reading speedo.
Since V2's rim is wider, when the same 90/80 tyre is put the 220's thinner rim the tyre will get "pinched" by the alloy, and thus it forms a slightly taller side profile. But how much more from 72mm no calculation that I know of will tell you that.
Yes, it won't the stock requirement of 90/90 = 81mm, but it will be somewhere between 72mm and 81mm.
Thanks now my decision to choose got even tougher
LOLGood you were saved, the PSD is just no good on the 220. I mean it was awesome for the first 2-3K kms but after that it was worse than stock.
