There really is nothing quite like the sound of a 125cc 2-stroke ripping around a motocross track! Sitting at the top of the small-bore pre-mix class with its strong motor, close ratio 6-speed gearbox, plush WP suspension, and razor sharp handling, our MC 125 is ready to shred!
All red and all-new! Fully redesigned from front to back, the sleek bodywork is incredibly ergonomic with larger contact surfaces and an improved rider triangle further enhancing control. The rad shrouds are shaped to help you better grip the bike as you get on the gas. There’s also a super grippy seat cover keeping you sat exactly where you need to be.
A new generation bike is nothing without a new frame, right? Taking the best traits from the old frame, which if you didn’t know combined razor-sharp cornering with confidence-inspiring straight line stability, our engineering wizards have made it even better! They’ve improved the anti-squat behavior for maximum traction when exiting corners. Throughout the frame, the wall thickness has been revised in certain areas to improve rider feedback and energy absorption. Finished with a red powder coating and grippy guards to prevent wear, which provide a little extra grip for your boots too.
For 2024, our 2-stroke motors are fuelled using Throttle Body Injection – a 39mm Keihin throttle body, to be precise – which works together with the ECU to deliver the perfect mix of fuel and air. The end result? Crisp, clean running motors that create smooth, strong power.
Fast is fun but slowing down is essential, which is why all GASGAS motocross bikes are fitted with high quality Braktec calipers and controls. With a 260mm front disk and a 220mm rear disk, both featuring a GASGAS specific design, braking performance is certainly impressive, which inspires riders to push harder, ride faster, and brake later using the redesigned lever.
Small, light, and fast at processing data – just what you need from an engine management system! The Vitesco Technologies component is the best in the business and includes a rollover sensor that cuts the ignition during big crashes, as well as feeding information to the hour meter.
