nope.. not for a go kart.. not for an adult..
if you want to convert it to a goKart for a 4yo.. maybe
it's too small, too slow and overall too underpowered..
so frame is of no use for a full size kart,
neither the motor nor the controller is up for the task of getting some fun out of it.
So yeah.. it is worth it if you want to make a micro kart for small kids,
or need a replacement part for your mobility scooter...
maybe even if you want to mess with the motor/controller to power something else...
if you want to make a go kart for yourself.. it's not even close!
