Christ. That does put things into perspective. Slightly worried by coming off having never rode a motorbike. Is it difficult at all? 125's aren't quick are they?
Ever ridden a bicycle? Exactly the same in terms of balance, in fact it's easier as you've got a motor generating the force to keep you stable.
Most will top out at between 60-70mph but any bike will only go as fast as you let it.
Haven't fallen off on my own accord. Mostly fallen off because people are stupid.
