The Trailmaster Mid XRX Go cart is a great intermediate kart for youth riders and is loaded with great safety features. There is a throttle governor on the gas pedal. All you have to do is run the screw in to slow it down or out to speed it up. This has a 200cc engine that puts out some pretty nice power. In the slowest position the go kart doesn’t run much faster than a person can run. Also, this gocart is made to ride two passengers and provides safety belts for both. Some great additions that we have made to this model is to add four wheel fully working and adjustable shocks.
