I've only got one [amusing crashing story] and it wasn't me.
Coming out of Stratford, summer 1998. Pulled up at the traffic lights next to a Triumph Speed Triple.
Lights go green, we both engage beans. Triumph lofts beautifully for about 100 metres. Drops down and then pretty much keels straight over.
I swiftly turn around and go back to the bloke.
"What happened?", said I.
"That's the first wheelie I've ever pulled", he said. "I was that shocked I fell over".
We giggled a bit!
