TrailMaster Mini XRX+ – Best First Go-Kart for Ages 4–10
Perfect First Go Karts For The Smallest Kiddos
The Trailmaster Mini XRX+ go kart is the perfect go kart for families looking to include the littlest kids in their outdoor fun. This little kart is built with many safety features to give you peace of mind. The seat and pedals have multiple adjustments- so you feel safe putting the tiniest family members in the driver's seat. Most 4 years old can drive. And it fits most kids up to age 10, so you know it's a great investment that will grow along with the kids.
The 7.0 hp engine is a mass produced Chinese small engine and boasts the same power and reliability as brands like Honda. The top speed is 13 mph but it can be governed down to 8mph easily.
This machine can handle off-road trails and obstacles like dirt, gravel, rough trails, corn fields, and most hills. It doesn't have any gears, just an automatic transmission in forward. If you think reverse gear makes it easy to maneuver, check out the Mini XRX-R+ it adds reverse and stops mom and dad from having to drag it out of the bushes (and let's face it- we all know the kids will end up in the bushes at some point).
It's perfect for taking the kids trail riding or just playing around the farm. Owning a go kart is an excellent opportunity for kids to learn about engines, preventive maintenance, and basic repairs. Whether you homeschool or just want to teach your kids practical life skills, a go kart is a great place to start.
Work While You Work, Play While You Play!
But it's not just for fun! The Mini XRX can work too. If you homestead like the Go Kart Masters family, your kids can load up tools and supplies to feed the farm animals, haul things around, and get chores done.
Our Go Kart Masters family is made up of Scott, Kim, and their 5 kids. Our 3 youngest love to ride the mini, and even use it to help on their adventures around the farm. We've put it to work hauling sticks to build forts for our outdoor reading club, taking buckets of feed out to the pasture-raised chickens, hauling groceries up from the truck, and more. We know you will love this kart because we do!
Peace Of Mind For Mom And Dad
The Mini XRX is packed full of safety features. We understand your concerns because we have small children too. This mini go kart is safer than a bicycle! We are 100% comfortable and confident putting our kids in this kart because it comes with the roll cage, safety harness, remote shut off, and more. Plus, we always have our kids wear a motocross helmet. Take a look at all the things that keep your kiddo safe on this kart:
- wide front end (very difficult to flip)
- full steel roll cage (ours crazy kids have flipped ours and didn't even bend a bar)
- 5 point safety harnesses on both seats
- adjustable pedals to make sure they can reach
- adjustable bench seat slides like an automobile style seat
- remote shutoff: simply hit a button on your key fob to shut it down
- 2 governors: adjust the top speed from 8-13mph
