My son started with pedal powered stuff and used to ride it through the autocross courses while we did early morning course walks.
Then graduated to the exact Razor ATV in the Original post.
Now he has a Briggs Raptor powered racing Kart. about a grand gets you in the door. he comes to all the events that run my car in. He is becoming quite good and is off the restrictor plates and throttle stops. As it is geared it tops out about 50 MPH.
