I choose my topic on quads because riding quads is one of my hobbies.  I love to ride quads because its fun and you can cover a lot of ground in a short time.  I have been riding since I was seven years old.  I started out on a 50cc, to learn how to ride.  Riding quads helped me judge distances and how to control a moving vehicle with brakes, shifting, and steering.  There are many different brands of quads such as Honda, Yamaha, Kawasaki, and Polaris.  There are many different styles and types such as racing or utility.  Quads have been around for many years due to their functional use.
