Sorry to hear about the accident, but the bike is repairable.
www.framestraightsystem.com can sort out the front end for about the Triumph dealer price on one fork tube.
They did the fork tubes and clamps for Mutato after I crashed.
The shift lever parts aren't that expensive, but the labor is a bi*ch.
If you can do the front end yourself then the insurance might cover the shifter repair.
