I had something similar jan 2011. Picked my brand new gsa up after it was on order for 3 months on the 4th Jan. On the 8th of jan, after 84 miles, i stopped behind a transit pickup at a junction, only for him to start reversing and hit the front of my bike with me and the misses on it.
The claim came to £750. He never informed his insurance company. So i telephoned them, only for them to say they would only act after 3months or if he telephones them and admits resposibility. Had to go through my insurance.
11 months later, a week before we was to attend court, he finally admitted responsibilty and i got my cheque.
Sorry to hear of your misfortune, and i hope you get it sorted quickly
