Tell me about it i had mine de-rezd and 3 weeks later my exhaust fell off and ripped off its housing with it, not only that the speedo stopped working all together any one reading this STAY AWAY from these MACHINES DONT MESS AROUND WITH A 50CC get yourself on a 125cc the best ones in my opinion available are the HONDA CBR 125 OR RIEJU RS2 MATRIX 125 these are both four stroke so no oil to buy and no expensive repairs you really cant go wrong with a four stroke there as tough as old boots .
