yes a qmb scoot motor will fit I just did my 07 agilty 50 with a new wildfire qmb motor.the only thing you will need to swap out is the stator and put the kymco stator in the new motor so you can use the same wire harnes. other wise you will need to do all the wireing over again. And beleave me you dont wana do that.and the tire size might be diff. Im rideing mine with a 10 inch on the back and a 12 inch on the front and all is ok.looks funny but I get to poit a to point b just fine.
