If the rear sprocket turns but not the wheel then the sprocket fasteners could not be securing the sprocket to the hub and you must have sheared sprocket bolts.

i have a megelli 125 s and im having the same issues can somebody please answer if you know where we can find the help we need i have been on the road for two months and this bike has been broken for 6 weeks of that time its very stressful. PLEASE!

try this links... it ll help u

remove the rear wheel & remove the rear sprocket and sprocket hub from rear wheel. (should just pull out) inspect the cush drive rubbers, chanches are they are destroyed & dissinagrated....replace them. check your wheel bearings in hub & sprocket plate.check axle. sprocket teeth & chain...reassemble and go riding..

just looking for wheels now. I can turn spacers if need be but if discs/sprockets don't match I'll be stuffed.The hubs and bearing sizes are the same but either could be made by AJP or Talon. Some handy things to know are ; 604 sprocket is no good for a 644 unless a 520 chain has been fitted. You will need to turn the rear tyre round if the wheell was on a 604 and its to go on a 644. Talon hubs use a different speedo drive to the AJP,,,
