Was wondering if 'body change' on bike is legal or not? For cars, I understand, but can bikes don't have a 'body' per se. More specifically, I have a custom paid legal Honda VTR250 and was planning to source a Honda CBR (NCP of course) and get everything out of it - fairing, engine, suspension, electrics, tyres etc and put it on the VTR chassis. Would that be equivalent to 'body-swap' on cars?

Any pointers in this regard will be appreciated!
