XX 125

XX 125 Launch Version

Whether you're a rookie or an expert rider, the 2-stroke roar of our XX125 will lift your heart at the first rev.

By the end of the first lap you'll have fallen in love with the perfect combination of ergonomics and manoeuvrability, agility and responsiveness.

So much fun, but also top class performance, to see off your rivals with a smile under your helmet!


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.


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.


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.



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!


But how cool is it to change a filter one-handed? No tools required, and ready to go again in a few seconds. What really counts is time on the seat, not pitstops.

So simple, it rhymes with performance.

Following careful flow analysis and trial runs with our riders, the Fantic engineers chose an optimised sizing for maximum performance. The new design also guarantees minimum impurities, so only fresh air enters the TwinAir filter.


Supplied with the bike in the form of additional extras, the launch kit mainly relates to chassis and ergonomics, and includes exactly the same components used by the Fantic Racing champions of the official MX and Enduro teams. The braking system has been completely revolutionised and features a 270mm Newfren floating disc at the front and a 240mm slotted disc at the rear. The brakes come with a set of Fantic Racing sintered brake pads. The new Factory Feeling design features 28mm Reikon handlebars and a set of Domino lock-on rotation-resistant grips. 

An extra crown wheel is provided, to always ensure you have the right drive ratio for the particular route or race circuits. To protect the chain and the crown wheel, the kit includes a chain guide specifically designed for racing. The official livery also extends to the red anodised components for the braking system and the engine oil feed. 

And that's not all: Motorex, official partner of Fantic Racing, has decided to provide all new riders of the Black Edition with the same products that official riders use for oil changes (Motorex Cross Power 2T, Motorex Racing Gear Oil 10w40).
