Never mind what sort of a GS you ride... 650 through to 1200.
If you are travelling at, lets say 60mph, I have to believe that the bottom of the tyre, in contact with the road, is stationary at the very moment it contacts the road surface... it must surely be so! Mustn't it? Or the tyre would be slipping/skidding... but it's not.
If this is the case then the top of the tyre must surely be doing 120mph to overtake, get in front of, go round, back to the bottom to travel backwards, and then be stationary when/where it touches the road surface. Must this be not so also.
How can one part, the contact patch, be stationary, when the rest of the tyre is picking up speed, accelerating, then slowing down to a standstill for a fraction of a second as it touches the ground again!
Gosh... I need a bier
