A bike designed for racing, but at the same time easy to handle. A racing ‘machine’, extremely performing from the moment the gate is lowered to the checkered flag. The XX 125 is the perfect combination of handling, design and ergonomics, agility and responsiveness. The Yamaha 125cc 2-stroke base, highly appreciated for performance, reliability and range of use, was an excellent starting point for the development of the XX project.
The Fantic 125 is the ideal bike both to accompany rookies in their competitive growth and for experienced riders looking for ambitious goals.The Fantic package, designed and built entirely in Italy, is the result of the work of expert motorists in the field of two-stroke and severe testing especially on the track. A perfect combination of engine performance, extraordinary chassis, ergonomics, agility, that overcomes any limit.


The Yamaha 2-stroke 125cc engine developed by Fantic demonstrates a perfect balance between linearity of use from low to medium RPM, accompanied by a significant explosion of power in the high rev range. The CDI control unit, developed directly by the Fantic Racing department, guarantees perfect combustion at every RPM. The expansion pipe by Arrow is specifically designed for MX use at high RPM. An aluminium silencer body and the 38mm Mikuni TMX carburettor complete the technical package of the engine. The high performance has been achieved by working on the optimisation of the engine, exhaust and CDI. This locates the new XX 125 at the top of its category.


Frame, suspension, rims, hubs, brakes – The aluminium semi-double cradle frame guarantees high levels of rigidity and lightness. Kayaba’s (KYB) suspension has been the benchmark in the off-road world for years and needs no introduction. KYB SSS (Speed Sensitive System) 48mm forks have 300mm of travel and are fully adjustable. These adapt to different levels of riding, from beginner to race professional in any condition. The mono shock absorber is also KYB, with a 315mm wheel travel. Brakes are by Nissin, delivering power and control for both front and rear, with a 270mm disc at the front and a 245mm disc at the rear. The equipment is completed by Excel 21 x 1.60 – 19 x 1.85 rims, on which Pirelli MX 80/100-21 – 100/90-19 series tyres are mounted. Standard gear ratio is 13:48.


Saddle, tank, plastics, etc – Fantic designers have worked in conjunction with the race test team, developing the ergonomics according to the requirements of modern motocross and supercross riding. After much research by the Fantic Racing department, the ergonomics delivers outstanding comfort and control to the rider. The introduction of a very slim tank, radiator covers, side panels and seat, allows the rider enhanced freedom of riding position. The central section of the bike is characterised by a slender line, delivering maximum control and stability at speed. The reduced central space enables a firm rider grip in the knee area and allows for greater freedom of movement and control in corners, jumps and whoops. The handlebars are made of 28mm aluminium.
