Full gas, hard on the brakes, rail the berm, scrub the next jump.
Nothing on the planet is more exhilarating than riding wide open around a motocross track.
Lap after lap, the intensity is certainly breathtaking but also massively rewarding. Taking place on circuits with big jumps, braking bumps, and deep ruts, motocross is a high-intensity sport that demands full focus and quick reactions from every single rider. As for the bikes, well, they’re built to handle everything you can throw at them, from their stiffer suspension to take the sting out of heavy landings to their fast accelerating motors. Motocross bikes are purpose-built for good times in the dirt. GASGAS is proud to offer many high-performance motocross models for the smallest of kids through to world champions and everyone else in between. So, which is the one for you?
Loved by little dirt shredders the world over, our awesome MC 50 certainly packs a punch! Looking just like the bigger bikes in our motocross line-up, the smallest 2-stroke we make features adjustable ergonomics that can easily be altered as children grow. Guaranteeing post-ride ear-to-ear grins, the MC 50 makes laps at the track so much fun for kids who just love to ride. Boasting best-in-class build quality with performance to match, the MC 50 is a mini motocrosser designed for the next generation of berm bashers to take on full-size circuits in style!
Our awesome little MC 65 is where riding pure motocross really begins. With its smooth-shifting manual transmission, this might be the first dirt bike on which kids learn how to change gears and, most importantly, when to do so to find the fast way around any circuit. Beyond this, the MC 65 is assembled with plenty of parts that you'll find on our bigger motocross bikes, but obviously scaled down to fit, underlining just how serious we are about making a competitive 65cc machine. We're talking the hydraulic clutch, all-red bodywork, MAXXIS tires, TWIN AIR air filter, and WP suspension. Yeah, we're stoked on our MC 65 and we know you will be too.
Together with our global team of talented, young test riders, we've developed what can only be described as an incredible 2-stroke motocross bike! From the new frame and WP shock to the improved motor and redesigned bodywork, just about everything is new, making for a seriously fresh MC 85 in 2025. As well as the increased performance, the riding experience is considerably improved too. Slimmer ergonomics and a handlebar bend created specifically for younger racers inspires confidence and makes laps at the track so much more enjoyable. The end result of all the changes is a bike that delivers incredible performance and rideability for such a small motorcycle. And if there's one thing that we can guarantee, it's that kids will absolutely love it!
The GASGAS MC 85 is the ultimate 2-stroke motocross bike for young riders ready to step up and show what they've got. Developed with input from international test riders and packed with race-proven tech, this bike delivers serious performance, confidence-inspiring handling, and full-size bike vibes in a scaled-down package. From its lightweight frame and WP suspension to its punchy motor and rider-focused ergonomics, the MC 85 is designed to help kids progress, compete, and have a blast doing it.
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, a frame with smooth 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!
