No they aren't. They honestly suck. The kinda just lug around no torque. I would highly recommend the kx or ktm 65cc. I used to own one and it pulled me around great. It'll totally loop you on your but if you try. However it is a two stroke so they are more finiky and you have to mix the gas. But it really is way better than the 50. Really the only way to get any power outta a minibike is a two stroke. A 65cc two stroke will totally whip a 90cc four stroke by far. Good Luck
