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).

Made by Ada Racing. Includes a Chrome Racing Air Filter, velocity stack and gasket.

Improves performance and quiets air intake noise.

This is the first engine upgrade you should invest in. Provides a very high tech look to your engine, sounds great, and doesn't require the oiling like the stock air filter does.

Same combo with choke below.

Add another 3 to 4 MPH with this racing head designed to fit the engine on your ScooterX Dirt Dog or X-Racer. Can be combined with the Powerpipe for a very fast combination. Replaces your existing top end.

This what I run on my Evo Powerpipe (pic on details). I like the look of the straight back exhaust.

I would not recommend running this without the pipe, since the exhaust will shoot straight down on to the scooter.

Same great performance as the original X-Can but with a new twist in style. With the stingers coming out the left side it not only has a cool look but also keeps oil off your rims. You can add the chrome elbows for an even cooler look. Also, a small baffle machined into the inside of the X-Can V.2 increase torque and lowers sound level slightly. Will increase overall performance and speed. This X-Can V.2 Fits the City Rider SX24 and of our Razorback Gas Scooters.

This performance pipe will fit your 52cc ScooterX Dirt Dog or XRacer gas scooter. You can expect a speed increase of 5 to 7 MPH and will notice your scooter is much stronger accelerating from low to high speed. This modification is by far the most powerful modification you can make to your scooter. Comes with full instructions.
