Almost forgot-not that I think anyone's interested but I'll post it anyway, it may help someone, somewhere along the line- at the 'event', we did a bit of comparing the 06 Speedie to the 07. Apart from the obvious (wheels, pipes, etc) we noticed that the upper fork shrouds on the 07's (inc America) are tapered (thicker at the bottom-look beefier); this may or may not be obvious. The other thing we noticed (don't ask how) is that the chain on the 07's is thicker.
That's it. Anoraks off.
