Back in the 70s I had childhood friends Coco & Cleo (twins brothers) which own a Mini Bike. On weekends I passed by their house for a ride around the subdivision. It was fun, loud and smoky little machine. It looks similar to this one
That's a cool little bike. I have 1050 miles on my 125cc Honda Monkey. I always like little bikes and still do. When I take mine out I go from about 2 to 40 miles each time.
