My bike was wrecked but it wasn't my fault

The best thing you can do in this case is take the bike to your local dealer and have them do a damage estimate. They will use factory part numbers and prices. Take the estimate to the insurance company. Do not deal with the person who hit the bike; he is out of the loop now. The insurance company will cut you a check and you can decide what needs to be fixed and what can be overlooked; remember that things like aftermarket levers and signals cost much less than factory parts. Don't forget to make the insurance pay for the damage estimate also. They should also cover the replacement of your damaged gear.
