Come off a road bike, only once, about 40 years ago, when i was a youngster. it was my 1st bike Suzuki GSX250, in those days you could have a 250 as learner.
However I had not learnt enough; so off I slid into an old ladies hedge, out she came "are you alright"
Yes I was fine, lucky really as i landed on soft ground.
I came off because there was dew on the ground, and I had never been round that corner, with it being damp.
Taught me a good lesson.
Trails bike: I've been off a good few times, on rough ground, trying to do too much etc.
Never hurt myself. I used to do off road motorbike tours in the mountains of Spain, 12 years ago. Not I can't even get on a motorbike.
I damaged y back when I was 24.
So that is why I have a small scooter now, so I don't have to throw my leg over.
