The sound of a 125cc 2-stroke ripping around a motocross track is one of life’s simple pleasures! Step forward the awesome MC 125. This little ripper is fully equipped with everything you’ll need to find the fastest way around any circuit. We’re talking a powerful motor, an updated frame for 2025 with improved handling, a close-ratio 6-speed gearbox, plush WP suspension, and strong brakes. Yep, that’s right, our MC 125 is the real deal, and it sits proudly at the top of the small-bore pre-mix class!

For 2025, our 2-stroke motors are fuelled using Throttle Body Injection – a 39mm Keihin throttle body, to be precise – which works together with the Engine Contol Unit (ECU) to deliver the perfect mix of fuel and air. The end result? Crisp, clean running motors that create smooth, strong power.

So much testing and development went into designing and building the frame last year, but our engineers have worked on refining things even further! Thanks to brand new, lighter, motor mounts, the flex characteristics of the frame are improved without any sacrifice to straight-line stability. Around the upper shock mount a little material has been removed while the wall thickness at the front of the frame is also slightly reduced, saving 300g. With all these revisions, which were tested by Red Bull GASGAS Factory Racing in MXGP, the bike is now much more settled through every corner.

All-new graphics spice things up for 2025 with the GASGAS logo emblazoned in black rather than white for a fresh twist. Still red, still durable, and still eye-catching, the distinctive design is applied using IML technology. This means they’re applied within the bodywork so your GASGAS will stay looking super fresh for a long, long time, even if you ride in gnarly conditions week after week.
