By putting a larger drive sprocket on your Dirt Dog or X-Racer you can raise the top speed of your gas scooter. However, you will sacrifice some power (you'll go faster but it's harder to climb a hill).

The best application for product is to combine it with a powerpipe or a high performance head kit; that way you will have the additional power to muscle the larger drive sprocket.

We sell both the powerpipes and the head kits for the Dirt Dogs and X-Racers on our site.
