The original dirt bike used to be the Razor MX650 36 volt 650 watt, I upgraded to 48 volt 1800 watt with a top speed of 29;mph This dirt bike is a little worn out, but all the parts function perfectly. I'm selling for parts but you can still ride it like a normal dirt bike. The original dirt bike cost $700 plus the upgrades cost another $320 for upgrades. It is pretty used up but no problems $600 is a good deal. This dirt bike will fit older kids. This dirt bike is also homemade. Width (handlebars) 26". length 52". height 34". But if you take handlebars of it would 28" high.
