Hey Austin..Check out my ALBUM phots and I have posted all the dimensions to build your own or you can get a good set up from GASMAN BIKES in Sydney..Remember the back sprocket is difficult to organise and because the frame is eliptical you cant attach to it..I dont like drilling holes in the frame and so the mount I built gets around this and its really stable..Good luck..The Stingrays look mean when there on the road..Use an 80cc motor to compensate for the weight factor of the bike but always say its a 48cc and lie to cops and say it a "heavy SLOW bike"..but it powers well..see ya ENO (Oz)
