Front shock Ohlins TTX T36PR1C1 for BMW R 1250 GS Adventure 2019 NO ESA MODEL (cod. BM 149 type: TTX)

How the TTX  system works
New revolutionary internal hydraulic  system was born, where the main difference is represented by the work of two  internal chambers which, thanks to the help of two valves, manage and regulate  the flow of the oil.

TTX hydraulic damping in the compression  phase
In the diagram you can see the oil path during the compression  damping phase.
The double chamber inside the shock absorber body is well  highlighted, the advantage of which is the reduction of the internal working  pressure as well as the reduction of the mechanical friction thanks to the  smaller piston.
A similar system for the front end, both the fork and the  cartridge work on the same principle

TTX hydraulic damping in the  extension phase
As for the compression phase, even during the  extension phase, the oil path and the influence that the double chamber has in  reducing pressure are highlighted.
This new way of interpreting and dampening  the stresses

The Advantages of the TTX System
Complex laboratory tests and  data acquisition on the track have finally written on paper the following  advantageous results:

Minor overheating of the mono
Less internal  working pressure
Constancy of operation
Better record sensitivity
Large  recording field
Better sensitivity in terms of perception of the obstacle of  the single shock absorber
Longer oil life
Longer life of mechanical  components
Less friction coefficient

OHLINS  SHOCK ABSORBER TTX GP
The most advanced, efficient and most reliable shock absorber from Ohlins, TTX GP is the top-of-the-range TOP shock absorber from top-of-the-range competitions such as MotoGP and SBK.
Suitable for all sports maxi, it is equipped with a 36mm  hydraulic piston with low friction coefficient, 14mm stem, and is equipped with  a renewed system of compression adjustment, extension and spring preload, more  precise and performing, as well as having the 'variable distance. Particularly  compact and light, it is also equipped with a separate tank pressurized in  nitrogen.

The new adjustment knobs make it easier to make changes with  or without tools.

Features
The most advanced double  tube TTX technology
Adjustment of return and compression obtained directly  from the MotoGP
Adjustment needles with different flow restriction behavior  to improve frame feedback
More extensive and more precise regulation  range
Fully separated extension and compression editing functions
