Fit Matters More Than Age
Not Sure Which Go-Kart to Buy?
Height alone does not tell us whether a kart fits. Leg length, pedal reach, experience, maturity, terrain and parental comfort all matter. Our guides explain the differences without pushing every family toward the biggest or most expensive model.
Start with the comparison, then contact us if you are still caught between two sizes.
We help you evaluate:
- Brake and throttle reach
- Rider experience and maturity
- Number and size of riders
- Farm, trail or backyard terrain
- How long you want the kart to fit
Experience You Can Actually Use
A Four-Generation Go-Kart Family
We are not a call center, and we do not sell machines we would not buy for our own family. Scott is a master mechanic, and our family has built, ridden, repaired and supported go-karts across four generations.
We have worked with TrailMaster since the brand came to the United States nearly 20 years ago and have helped close to 5,000 customers. That experience shapes our product recommendations, assembly resources, parts inventory and support after the sale.
What honesty looks like here
- We explain which model we would choose.
- We tell you when an upgrade is mostly cosmetic.
- We publish the downsides along with the benefits.
- We help owners find parts years after the sale.

Straight Answers
Before You Order
Is shipping really included?
Yes. Go-karts, mini bikes and dirt bikes include shipping within the lower 48 states. Complete machines ship by freight or parcel service depending on the product. Sales tax is calculated at checkout wherever legally required.
How much assembly is required?
Go-karts normally arrive about 80% assembled. The engine, steering, brakes and electrical system are generally installed. Most families spend around two hours completing assembly with ordinary metric tools, and a second adult is helpful for the roll cage and lifting.
Can you help me choose the right size?
Yes. We look at pedal reach, experience, maturity, terrain, number of riders and parental comfort - not age alone. Start with our comparison resources, then contact us if you are still deciding between two models.
What happens if I need help after delivery?
GoKartMasters customers receive access to our assembly resources, owner education and complimentary product support. We also stock TrailMaster OEM parts and publish free manuals, videos and troubleshooting guides for TrailMaster owners.
What does the Master Warranty cover?
Our 12-month limited parts warranty covers approved replacement parts for qualifying manufacturer defects. It does not replace routine maintenance, wear items, labor or damage caused by misuse. Read the complete policy before ordering.

We strongly suggest all go kart riders wear a DOT approved full face helmet. Operating a go kart comes with risks and you should prepare yourself and other riders with the proper gear. For children, we recommend a helmet and a set of goggles. For adults, there are lots of options with built in face shields. See some of our suggestions below.
