Because you aren't claiming against your insurance then hopefully you won't lose your NCD while the dispute remains. Like the others said be real clear with your insurers that you do not accept liability, under no circumstances should they pay up. You might have to sit it out for a couple of years if the other folks threaten legal action and see it through but if its the front of her car, side of your bike, then its her who needs the witnesses and without any other evidence (make sure to take pictures of your damage) I can't see you losing. Hopefully she or the insurers will buckle quicker.
