140? wow! when i got mine the guy said mine would run 70 and that to me was crazy but i guess ive been taught what crazy is now. at my house id prolly never get out of 1st gear on that thing lol
that wouldnt be any fun because every time you wanted to ride it you would have to chage the rear tires, i bet it goes trought them like crazy=P would be a sweet quad to customize for hill climb=D
