The small but ultra-performance 125cc 2-stroke engine needs no introduction, apart from knowing it's the Junior 2021 Champion.

Thanks to intense research and meticulous work on the cylinder, piston and connecting rod, our 125 has never been so powerful and enjoyable to ride.

The cherry on the cake is the Kehin 38mm carburettor which, thanks to a solenoid-controlled power jet, further enhances performance when it's needed on the track.

The XX125 boasts the most competitive frame and suspension in its class. An exceptionally precise high-tech semi-double cradle frame in aluminium for optimum rigidity and lightness, weighing just 8 kg. How does it feel to ride? Maximum precision and responsiveness for top performance in any conditions.

Kayaba suspension has been the benchmark for off-road bikes for years and needs no introduction.  The Kayaba SSS (Speed Sensitive System) 48mm closed cartridge pressurised forks have 300mm of travel and are fully adjustable for pre-load, extension and compression. Perfect adaptation for any level of riding, from beginner to race professional. The mono shock absorber is also Kayaba, with 315mm wheel travel.

How's the track today? Wet sand? Perfectly packed dirt? No problem.

The XX125 comes with two engine mapping settings accessed from the handlebars. 

The Soft Mapping delays ignition timing, giving a more gentle delivery and is recommended for a more treacherous terrain, for a bike that's always responsive and manageable, without sacrificing the adrenaline rush of maximum power.

A fantastic chrome-plated expansion pipe will tell the world loud and clear about the wonders of two-stroke.

Our R&D department worked hard on a component that's key to performance and designed specifically for high-level MX use.

Thanks to the cast aluminium silencer, we also ensure compliance with FIM regulations.

100% race ready!
