Accident on 7.5.06

Hello people ! I ask you to do the following accident some time afterwards .. in town .. not faster than 55 kmh. in front of me 2 pkw. the front wanted at ner ampel with yellow still ganzsischen ..ihms not enough and makes a full braking .. the pkw behind also makes a full braking .. I had correct safety distance with the motorcycle ( police proven ) , nevertheless it had not been enough for me .. the motorcycle slips away and I bang right in front of me . The police i had written me without a long testimony survey and so as guilty in the protocol. I told the police officer how it could be that if I had the right distance and the right speed. how I could be to blame. to all happiness is the penner who first braked off and no one has a number plate, but I have about 4 undisputed witnesses who can confirm this. How do you judge this situation? it is known that the , de rhinten up is to blame.. but does this also apply in such a case ? I have no bock to pay the complete front and fork damage to the new r6 itself. thank you for your contributions
