Product Overview


 Trailmaster Eagle Series Mid XRX Go Kart with Reverse


Trailmaster Simply Offers the Best Go Karts for Sale Online

We've taken the best and made it even better. The TrailMaster Mid XRX-R is almost identical to the Mid XRX except this kart has reverse just like the larger 150 karts. All the same fun as the Mid XRX without having to get out of the kart to push it to back up.

Premium Comfort & Safety

This offroad go-kart was designed for a 6 year old to a 12 year old rider but can accommodate a small to average size adult. The seating area is roomy enough for an adult plus an average sized 8 year old. The TrailMaster Mid XRX/R has an adjustable driver's seat so that two different sized riders can ride without being uncomfortable. The Mid XRX-R has high side rails, tall top bars for plenty of head room and 5-point seat belts for a safe and comfortable ride. This go kart has large tires and fenders and can accommodate open grass fields, gravel driveways, pastures and intermediate trails. 

Performance & Handling Are Industry Leading

The TrailMaster Mid XRX/R is built tough with an automotive inspired steering and front suspension. The front spindles are tall, which add strength, and the rack and pinion makes for quick and easy turning. The TrailMaster Mid XRX-R incorporates a short wheel base for tight turns. The top speed of the Mid XRX-R is easily adjusted at the pedal from 30 mph down to 8 miles per hour. The Mid's engine is one of the most popular designs in the world with all parts readily available. The TrailMaster Mid comes to a quick stop with hydraulic disc brakes for both rear wheels.


Newly updated in 2024, all Mid size go karts feature a 7.0hp engine with several upgraded components fo rmore durability and lower maintenance needs..

Hands-On Trailmaster Go Kart Research

The TrailMaster Mid XRX-R go-kart is the best mid size kids go kart on the market. It features a very simple CVT drive system which is superior to the 110cc and 125cc go-karts with complicated gearboxes that are difficult to operate and know to have excessive failures. The Mid XRX-R electrical system is simple. The go kart can still be operated even if all of the wires are removed because of the pull recoil starter and self-contained engine (ignition, carburetor, and muffler are made to the engine). The TrailMaster Mid XRX-R is tough and loaded with standard features including reverse (Mid XRX-R only). The Mid XRX-R has the following upgrades compared to the TrailMaster Mid XRS.

  • Reverse
  • Heavy Duty Frame
  • Rugged Suspension with Longer Travel and Larger Wheels
  • Fenders Front and Rear
  • Individual Bucket Seath w/ Quick Adjust Driver's Seat
  • Fabric Canopy Top 
  • Headlights
  • Horns
  • Electric Start & Pull Start
  • Rear Cargo Rack
  • Large Fuel Tank

    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 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.
