HI Guy's I am currently searching ebay & through bike mags for a 50 for my son so he can learn to ride. I still dont know wether I will go new or secondhand. New seem to be about $1500 - $1800, second hand I have seen for around the $750 - $1000 Mark. (Mid 90's Models Onwards) I think all the 50's are pretty similar, Shaft drive & semi auto boxes etc, Maybe there is no real difference & it's just preference to a brand. Any way I would like any info you guy's could give me on the various types & maybe also which bike people stared their riding career's on. All info received is much appreciated, Thanks in advance. DAVE P.S. Should I consider such bikes as Thumbstar/Yomoto etc found on ebay, the ones with engine brands such as Loncin & Others????
