Hey I'm looking to swap in a 125 to the kx100 frame aswell as electronics and radiator..theres a second pair of radiator guards on the other side so I know it'll fir but has anyone ever done this swap or tried to do the 125 swap..trying to do this as I will be getting a KTM 144 soon but don't want to part with the kx100 or my 125 engine sitting here. :cool:
