The number of dealers stocking parts is probably few and far between. Kymco 123 told me they only stock nuts, bolts and
screws. These days to inventory parts can be a costly venture. I just ordered the stator and rectifier for my Xciting 250. I always make a point to compare parts for both the Xciting and my GV. Both have 250cc GY-6 engines. Beyond this the sliders, belts, rectifier and stator are different. Brake Pads however are the same and this is a part that may be found more easily in stock. It's too bad because Kymco does not manufacture each individual part, but source them from other
suppliers. That is... some parts may be interchangeable with Yamaha or Honda. You have to find someone really well
versed in that though. Also remember, your internet part may be cheaper, but there's shipping and taxes on top of that.
I have used Stadium Yamaha with good success, but beware most parts take a week or two to get.
