Serious Power For Serious Riders

Zongshen 125cc engine, manual clutch

The Zongshen-brand 125cc, 4-stroke engine with a manual clutch and multi-speed gearbox gives experienced young riders real gear-changing control, powered through a JINGKE PZ26 carburetor.

Go Further, Ride Smoother

710mm inverted front fork and 17in/14in wheels

A longer-travel 710mm inverted front fork and bigger aluminium wheels (17-inch front, 14-inch rear) than the standard 125cc Pro deliver a smoother, more capable ride over rougher trail terrain.

Confidence-Building Control

Hydraulic disc brakes, front and rear

Hydraulic disc brakes on both wheels give riders the stopping confidence to match the Pro X's extra pace and travel, with a durable steel fuel tank and KMC golden final drive chain rounding out the build.

Choose Your Colour

Available in Blue, Red or Black

The GMX 125cc Pro X comes in three colourways with a coloured alloy hub to match your chosen variant, so your young rider can pick the look that suits them best.
