Youth-Friendly Off-Road Go-Kart with Adjustable Speed Control & Remote Kill Switch

The TrailMaster Mini XRX+ is designed to grow with young riders, combining a generously sized frame, wider seating, adjustable pedals, and a sliding seat to accommodate children from approximately ages 4–10.

Powered by a reliable 163cc, 7HP air-cooled 4-stroke engine, the Mini XRX+ features electric start with a pull-start backup and a fully automatic transmission with reverse. Its two-wheel-drive system uses a centrifugal clutch for straightforward operation, while full suspension helps provide a smoother ride across suitable off-road terrain.

With dual high-back seats, a 5-point safety harness, hydraulic rear disc brake, LED headlight, horn, cargo rack, and heavy-duty frame, the Mini XRX+ is built for supervised recreational off-road riding.
