TrailMaster Mid XRX-R Go Kart For Kids w/ Reverse, Electric Start, 5 point harness

Q: What’s the difference between the Mid XRX and the Mid XRX-R?

The Mid XRX-R adds reverse to the automatic CVT drivetrain, making it easier to maneuver in tight spaces and on trails.

Q: What ages/size does the Mid XRX-R fit?

Typically right for riders around 8–12. Height and inseam matter—check seat-to-pedal fit and the Go-Kart Sizing Guide if your rider is taller or shorter than average.

Q: How fast does it go, and can I limit speed?

Real-world top speed varies by weight and terrain. Parents can limit speed using the built-in throttle governor and increase it gradually as skills improve.

Final assembly is straightforward with basic tools. We provide setup tips and an assembly playlist. Always torque fasteners and verify brakes and throttle before the first ride.

Full roll cage, 5-point harnesses, hydraulic disc braking, and an adjustable throttle governor. Pair with a DOT youth helmet and protective gear.

Q: Do you offer local pickup or faster delivery?

Local pickup is available at the Garland, Texas distributor warehouse (often ready in 3–4 days). Freight transit times vary by region; the Pacific Northwest and New England typically take longer.

Q: What maintenance should I plan for?

Top off oil at assembly; perform a break-in service around 5 hours; adjust the chain and check tires regularly; use quality fuel with stabilizer if needed; keep the battery on a maintainer when idle; store covered and indoors.

Q: Which colors sell out first for the Mid series?

Pink typically sells out first during the holidays, followed by other popular Mid colors. Order early if you need a specific color.

❓ Mid XRX-R FAQs

What’s the difference between the Mid XRX and the Mid XRX-R?

The Mid XRX-R adds reverse to the automatic CVT drivetrain. That makes it easier to maneuver in tight spaces or back out on trails. Many families prefer the “R” for everyday convenience.

What ages/size does the Mid XRX-R fit?

It’s typically right for riders around 8–12. Height/inseam matter—check seat-to-pedal fit and our Go-Kart Sizing Guide if your rider is significantly taller/shorter than average.

How fast does it go, and can I limit speed?

The factory rated top speed in around 24 mph. Actual top speed depends on rider weight and terrain. Use the built-in throttle governor to cap speed for new riders. Increase gradually as skills improve.

Is assembly difficult?

Final assembly is straightforward with basic tools (steering wheel, wheels, roll cage sections, battery, etc.). We send a full color photo guided assembly book with setup tips, and our assembly playlist helps you finish confidently with video tutorial.

Will it arrive before Christmas?

Most orders arrive within 10-14 days of initial order. We recommend ordering by Dec 6–7 for the safest Christmas Eve window. Dec 10 is last-chance and can be risky due to freight slowdowns, especially to the Pacific Northwest and New England.

What safety features does it include?

A full roll cage, 5-point harnesses, hydraulic disc braking, and an adjustable throttle governor. Wide form axle makes for easy handling and bucket seats keep riders securely seated. Pair with a DOT youth helmet and gear for best protection.

Do you offer local pickup or faster delivery?

Local pickup can be arranged at our Garland, TX distributor warehouse (often ready in 3–4 days). Freight delivery times vary by region; PNW/NE typically take the longest.

What maintenance should I plan for?

Top off oil at assembly; perform a break-in service around 5 hours; keep the chain adjusted and tires inflated. Use quality fuel (non-ethanol preferred; add stabilizer if using pump gas). Keep the battery on a maintainer when idle and store covered/indoors. We will provide service bulletins for these tasks.

Which colors sell out first for the Mid series?

Pink is historically the first to sell out during the holidays, followed by other popular Mid colors. If you need a specific color for Christmas, order early.

We have 3 trailmaster go karts and several dirt bikes. The Mid XRXR is the family favorite. We can all ride it. It does donuts, jumps, tackles hills and more. Wish it had racing style seatbelts. it was super easy to put together with go kart masters assembly guide booklet.

XRX-R

Posted by Greg Hess on Dec 29th 2024

Kart seems to be good. Shipping not so good. I understand that shipping from over seas is not always good. The mounts that would hold the kart down while shipping were broken. Several pieces of the kart are scratched from being able to move around. Parts bag ripped open with parts missing. Go kart masters has handled the issue with professional help. Would buy from again.

Great Go kart for kids

Posted by Drew Wren on Dec 27th 2023

The kart was very easy to assemble with just one person. The video that was sent with the confirmation email was very helpful and easy to follow. The kart is a great size for a 9 year. I will be buying another kart in the near future.

Decent Kart for the Price

Posted by Nate on Dec 27th 2016

GoKartMasters have been great to work with, and that's always a key plus! I would purchase from these guys again. 30 days into having this kart, I give it 4 stars on performance. It appears to be built fairly well and the engine runs good. The choke leaves a bit to be desired, and the kart will take a few cranks to get started the first time. The description says up to 30mph, but you won't be getting close to that number with an adult and child on board. Assembly- Don't let anyone fool you...with the correct assortment of tools and two solidly minded adults, this product took 2-1/2 hours to put together. Thanks to gokartmasters for this, because the instructions they send you are very detailed vs. the instructions from the manufacturer. A key note here: they've got the instructions for the tires and fenders backwards, which added a solid 30 minutes to our assembly. PUT YOUR FENDERS ON FIRST. If you put the tires on first, like the instructions call for, you'll need some really fancy tool accessories to get to the tight screw holes for the fenders, or more likely, you'll just pull the tires back off to put the fenders on. Oh- for those of you wondering if the $150 charge for the reverse feature is worth it--- YES. And yes some more. We've used it every single time we've ran the kart. The short on this is you're getting a solid kart for the $$$ from a company that stands behind their products and customers. Their are lots of .coms out there carrying this item, but dig a little and you'll find that gokartmasters.com is the best choice across the board.

Great cart with a warranty that is NO JOKE!

Posted by Rob on Dec 1st 2016

I purchased a mid xrx-r for my daughters about 5 months ago. This has been a great cart for them. I can barely fit in it as I am 6'0 for I was able to squeeze in to help teach them how to drive it. For the price I expected a solid cart with a dependable engine and drive system and that is what I got. The only minor issue I had is that the battery took a crap on my. No big deal except that the only writing on the battery is Chinese. I contacted the company purely to find out the specs on the battery so that I could go buy a new one here it town. Upon contacting the company I was informed that the company stood by their warranty 110% and that they would be sending me a new battery at no charge. I was in no way expecting that and didn't even ask for it, but I was informed that the company stands by their warranty and that is how they take care of their customers. I will be coming back when my girls out grow this cart.

Two Different Ages

Posted by Jillian on Aug 9th 2016

The Mid XRX-R is definitely a perfect fit for our nine-year-old. The seat is adjustable so that our five-year-old can reach and drive too. It's convenient that the top speed can be adjusted easily on the backside of the gas pedal.
