Get 3 repair estimates, include a new helmet, tax and any replacement of any clothing damaged. If your frame got scratched, get an estimate to repaint it. Give her insurance the 2 highest estimates + repaint and make her insurance pay for the full amount of the lower estimate + repaint you gave them.

If you do not get full repair cost, you can then get some factory touchup paint (or closely matching nail polish); do the paint touchup yourself and use the rest of the paint money for repairs.
