Dave Moss does 3 sessions on Motorcycle Suspension Set-ups and how Tires and suspensions coincide. I found it pretty handy, didn't know if it was old news figured i'd post about it though.

Oh and went the flash site comes up, click on the tool box on the left.
Start with the first video and go to 3, makes a hell of a lot more sence to watch them in order...trust me...Don't ask... ::)
Post up here if it was useful at all to.
