When i was a youngster circa 1969 (12 or 13 years-old) I purchased my very own Bonanza mini-bike just like Ricky, the neighbor across the street, was "driving". This was at the Calif-Kart Sales showroom in San Jose, CA (see add photo). If I remember correctly, mine had no lights, no rear suspension, and a worthless front suspension (hardly any fork travel at all). I changed the jack-shaft sprocket for more top speed. It was one speed with the centrifugal clutch. My next door neighbor Chris, then joined the "club" when he purchased a purple Taco brand machine. I drove mine mainly on Dads 200-plus acre agricultural property in Milpitas, CA. But at home, we had a "circular" type driveway and there I would run laps down the sidewalk directly in front of our house then into the curved driveway and back around again. I did not use the paved street in front of the house. One day I challenge Chris to a drag race. I use the short stretch of sidewalk (as usual) in front of our house and he sets up on the street alongside me. Off we go and up pulls a CHP patrol car. Gives us both citations and Dad has to later accompany me to juvenile court where we met with some government official where I expressed my remorse. (In 1983, I graduated from the CHP Academy, first in my class). I am guessing a neighbor must have called the CHP on us. It was the only time I saw a CHP patrol car in our quiet neighborhood.
