❓ Mini XRX-R FAQs

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

The Mini XRX-R adds reverse to the XRX model, making parking and maneuverability easier. Many parents prefer the “R” model for everyday convenience.

What ages and sizes fit the Mini XRX-R?

Typically right for ages4-10 and riders under ~4’6”. Both age and experience matter—confirm with our Go-Kart Sizing Guide.

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

Real-world top speed depends on rider weight and terrain. Use the built-in throttle governor to cap speed for beginners, increasing gradually as skills improve. The mini features two governor options.

Is assembly difficult?

Karts arrive 85% assembled. Final assembly is straightforward with basic tools (steering wheel, wheels, roll cage sections, battery, etc.). We send setup tips, and our YouTube assembly playlist helps you finish confidently.

Will it arrive before Christmas?

Most orders arrive within 7-10 days of initial order. Longest shipping time is 10-14 days. 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, disc braking, and an adjustable throttle governor. Pair with a DOT youth helmet and protective gear.

Do you offer local pickup or faster delivery?

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

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.

Which colors sell out first?

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