Barn said:Yes I agree they are all running 16.5" rim sizes. They have been experimenting with that for years now but I think it's finally a GP standard. It allows for the tire to stand 1" taller with the same centre line circumference.
As for what I was really after was the width/sidewall ratio. For front and rear. I'm surprised they are only using 190's. As for sidewall ratios, those are some pretty odd numbers.
SPL - where did you find those tire sizes?
Great question. My guess is that the smaller bike still will put out enough HP to spin up whatever size tire they throw on there, so they'll probably stick with 190-205mmballistic04_750 said:Wonder if smaller tread widths will be used next yr in light of the transition down to 800cc machines?
