Straightening a frame is very easy. It's actually two issues you need to deal with, the bent frame causing the fender rub and the bent steering stop marking the tank. I have a theory why they bend in the first place , its because kids don't have the physical strength to activate the hand brake and the machine hit things dead on. I've straightened two now and haven't been easy on them. No repeat issues so far. PM me if you need straightening pictures.
