GMX 125cc Dirt Bike – Red/White Off-Road Motorbike for Older Kids, Teens, and Learners

The GMX Moto125 Dirt Bike in red and white is built tough for riders who are ready to shift into gear—literally.

This 125cc off-road motorbike is a solid pick for older kids, teens, and beginners who want to take the next step into trail or paddock riding with full control and confidence.

At its heart is a punchy 125cc 4-stroke engine with a manual 4-speed gearbox and clutch. It starts with a kick and delivers steady power across different terrains.

From dirt trails to rough paddocks, this bike’s setup keeps the ride smooth and gives the rider full control throughout.

The frame is made from strong chrome steel and welded with precision, giving it the strength to handle bumps and hard riding.

Suspension is handled by a high-performance upside-down fork at the front and a rear shock absorber that soaks up the rough stuff. The bike also features front and rear hydraulic disc brakes, giving you safe and consistent stopping when you need it most.

This model has a taller ride with a 720mm seat height and a 1160mm wheelbase, offering stable handling for growing riders.

The steel handlebar, CRF50-style fairing, and updated exhaust give it a sharp look that matches its performance. With a 4-litre fuel tank and a rider weight limit of 100kg, it’s built for longer sessions and bigger adventures.

It arrives mostly assembled, but for the safest ride, we recommend having a qualified mechanic complete the setup.

With its bold red and white finish, this version of the Moto125 looks as fast as it rides.
