The KTM company was founded in 1953. Austrian engineer Hans Trankenpolz.

The company name is derived from Kraftfahrzeuge Trunkenpolz Mattighofen. Mattihoffen is the city where the plant was located. Trankenpolz was initially involved in the repair, and then the production of bicycles and motorcycles.

By the beginning of the 90s, a unified concept and philosophy of the company had developed: before a model reaches the consumer, it must be tested in competitions.

KTM's motto is simple - all machines are Ready to Race. And in this philosophy there are no exceptions.

KTM always strives to present the best and the most refined to the consumer.

The basis, the skeleton of any bicycle, is the frame. The "character" of the bike, its behavior on the track, depends on the frame.

The stiffer the frame, the better the handling, the responsiveness of the apparatus, the clearer the trajectory, the easier the lift, the less energy is wasted. In a word, you press the pedal - and all efforts are instantly transformed into movement.

Rigid frames offer outstanding rolling performance on both highway and soft terrain.

On rough terrain, the rigid frame loses roll, the bike "shuts up", even the best suspension fork does not save.

The movement continues only as long as you "screw in". For a good roll over the "intersection", the frame needs to dampen (ie partially absorb) vibrations.

The classic solution is the active rear triangle of the frame, consisting of "active" - profiled feathers and struts. When driving on rugged terrain, the feathers function as powerful springs, i.e. slightly deformed, springy, removing vibrations from the rear wheel axle.

The stances also "play" providing some movement of the feathers and partially absorbing vibration.

All this work is practically invisible to the naked eye, but even a non-professional can feel the difference in movement, and especially at long distances.

However, this design also has a pronounced negative point - the combination of a rigid front triangle with an active "tail", as a rule, leads to insignificant mobility (buildup) of the carriage assembly.

Those. the frame loses torsional rigidity, which leads to, albeit insignificant, but still a loss of energy during active pedaling (for example, when climbing a hill while standing). Some of the forces are wasted - on deformation of the frame.

The bike becomes "sluggish", worse "tears" from the start, worse "writes" the trajectory.

This behavior is acceptable, and even good for marathon or touring cars, where some comfort or the ability to "take on board" a hefty load will not interfere. But for a professional racing machine, this is completely unacceptable.

In addition, the racing frame must be extremely lightweight and have maximum safety margin.

At the same time, it is desirable that it should be resistant to mechanical damage, therefore, have a good service life.
