Dropped mine a couple of times;
One time late at night just finished work, really tired stopped at some lights & forgot to put my foot down .doh
Another time in Chips i saw a old guy bleeding on the floor his mrs was with him but nevertheless i stopped on a slight hill to help,he said he was ok ,proceeded to get back on the bike & it moved to put me off balance, i ended up on the deck
Funny thing was he then rushed over to me to see if i was ok :-[ :-[
Been riding for over 25 years & still fall off
