Anyone looking for a candidate for victory at the Junior World Championship can hardly ignore the 125 SX. Its speed-hungry engine, always good for a sprint, has recovered even more performance for the current season. It is impossible to ignore the 125 SX, neither on the cross track nor in the career plan of a future champion, if only because of the completely new frame and the new progressive rear suspension. indirect.
New intake pipe
The flow-optimized intake flange of the 125 SX, between the airbox and the carburetor, now ensures even better engine breathing. The water-cooled two-stroke engine thus revs even better and offers more power over the entire range of revs..
New muffler
The new silencer of the 125 SX has not only improved in quality, but its optimized silencer, in conjunction with the exhaust control, provides an additional, explosive but controllable power take-off..
New frame
Completely redesigned, the frame of the 125 SX, made of high-quality chrome-molybdenum steel, is not only extremely light and torsion-resistant. It is also distinguished by its particularly balanced geometry which combines childlike handling and formidable precision..
New Linkage rear suspension.
Now even KTM’s MX program two-stroke comes equipped with the complex link-link rear suspension. The articulation of the shock absorber by means of a connecting rod system provides great progressiveness as well as a wide adjustment range. The 125 SX is thus subscribed to the podium, even on the most brutal Motocross tracks..
New swing arm
The new Linkage rear suspension is mated to the new cast aluminum swingarm, designed for optimum resistance to lateral torsion and perfectly defined longitudinal flexibility. The 125 SX owes a great deal to him for its great in-line stability, extraordinary handling and extreme traction..
New setting of the telescopic fork
The inverted telescopic fork has been further improved, featuring closed cartridge technology and a little tighter adjustment for even less bottoming out. The WP fork with its 48 mm (1.89 in) tubes thus contributes significantly to the extraordinary handling of the 125 SX..
Bodywork
The trim of the 125 SX with the slim lines of the saddle and the spoiler and its excellent contact points further perfects its ergonomics and makes it even easier and more precise to drive..
