What Model is My Go Kart?

If you need to order parts for your Trailmaster go kart, it will be necessary to know what model of go kart you have. If you don't have an original purchase invoice or if you bought the Trailmaster go-kart secondhand, you might be wondering how to find out what model go kart you have. The most obvious way to find your go kart model is to look on either side of the main frame or near the front of the body. If this decal is missing, you can use the guide below to help identify your go-kart model.
