I thought she'd given you the money?
Similar sort of thing happened to my workmate, a young woman did a u-turn on him on his GSX600 near work, admitted liabilty straight away and said they would pay cash for the damage (her mum was the passenger).
A week later and the mum said it was her that was driving and it was his fault?
He never got a penny out of it.
What sort of damage are we talking about on your bike?
