TrailMaster MINI XRX+ Kids Go Kart - 5.5hp Gas Engine, Electric Start, Remote Kill


Description

The TrailMaster MINI XRX+ is a performance-inspired kids go-kart built for riders ages 4-9, delivering a thrilling yet safe introduction to the world of motorsports. Powered by a reliable 163cc, 5.5hp 4-stroke OHV gas engine, it offers real go-kart performance in a compact, kid-sized package. Its sporty design takes cues from the larger TrailMaster XRS, so your young driver will look and feel like they're in a race machine. Safety is engineered throughout - from the built-in speed governor and safety seatbelt to padded brush guards and side railings.

Parents will appreciate the two remote start/kill fobs that allow them to shut down the kart from up to 100 yards away, giving ultimate peace of mind on every ride. With full front and rear suspension, rack and pinion steering, and a top speed capped at 12 mph, the MINI XRX+ strikes the perfect balance between excitement and control for young drivers.

FAQ

What ages is the TrailMaster MINI XRX+ designed for?

The MINI XRX+ is designed for kids ages 4-9. The adjustable pedal and speed governor make it easy to tailor the kart's performance to your child's size and skill level, so it works well across a wide age range within that window.

How fast does this go-kart go?

At full throttle with the governor at its loosest setting, the MINI XRX+ tops out at approximately 12.4 mph. For younger or less experienced riders, the speed governor can be tightened down to limit top speed to around 4 mph - making it a safe choice for first-time riders.

How does the remote kill fob work?

The MINI XRX+ includes two remote controller fobs that allow a parent or supervisor to shut the engine off from up to 100 yards away. This is a key safety feature - if the kart heads somewhere unsafe or the rider gets startled, you can stop the kart instantly without having to chase it down.

Does it come assembled, or do I need to put it together?

The MINI XRX+ ships in a crate and is described as mostly assembled. Some final assembly steps (such as attaching mirrors, the steering wheel, or seat belt) may be required. Most customers complete setup in under an hour with basic hand tools.

What surfaces can this go-kart be used on?

The MINI XRX+ is built for outdoor use and performs well on a variety of surfaces including packed dirt, gravel, grass, and pavement. Its full front and rear suspension helps absorb bumps and uneven terrain for a smoother ride.

What is the warranty on the MINI XRX+?

The MINI XRX+ includes a 30/90 parts warranty. This typically means 30 days on wear items and 90 days on mechanical/engine parts. Factory replacement parts are available. Contact us for specific warranty questions or claims support.
