Here I am on my first motorbike. In the neighborhood where I grew up on the extreme far west side of Denver, Colorado, back in 1963/4 all the guys on my block had some kind of bike.
There was no way to get around. It was miles to walk anywhere and there was no bus transportation. So, we were all able to convert that into getting our parents to let us buy a bike. Back then, you could get a driver's license at age 14 (me in the pic at age 14), if your bike was 6 hp or less.
I still love this Yamaha trail bike. I rode it for miles, over all kinds of terrain. There were the mountains to the west. We regularly rode up one of the narrow canyons of Bear Creek or Deer Creek and went swimming in the creek. Or sometimes we would use inner tubes to float down the cold creek waters on a hot summer day.
What was your first bike, and what did you do on it?
