It's probably Hyperpro's Type 469 3D Shock as listed for the Versys. The rising-rate full progressively wound spring is available in purple or black.
"The 469 shock is named 3D due to the design possibilities of this shock by developing a motorbike specific shock. This full adjustable shock has proved its qualities on the racetracks and roads through the world for several years already. The successor of this shock will be Type 462.
Feature: rebound adjustment / high/low speed compression / optional length adjustment / optional hydraulic preload adjuster."
"Because we believe and we know there is room for improvement, Hyperpro has developed the new 3D shock. Hyperpro is able to guarantee one hundred percent quality, because this shock is manufactured totally in-house. The many light-weight billet aluminium parts have been CNC machined in the Hyperpro factory as well. We never use (more fragile) cast parts for our products.
The compression and rebound damping are both completely adjustable with high and low speed adjustments for compression damping .
We use a rising-rate full progressively wound spring for better absorption of small bumps and pavement "chop" while still offering good control on bigger bumps or for higher rates of speed.
We use a larger shaft diameter for more strength and more oil displacement which allows better fine tuning of damping. Larger diameter also allows for greater durability.
Our 16mm shaft (2 mm larger than Ohlins shock) has a CNC - carbon nitrite coating to minimize stiction (just like you see on high end forks).
Hyperpro uses a new seal design which has been proven through the rigors of motorcross in Europe to provide superb durability and very low stiction. Tests between this seal and the standard competitors seal show 3x the life...
The Hyperpro 3 D shock utilizes bladder technology in the reservoir to separate the oil from the nitrogen gas. Other manufacturers use a floating piston. A floating piston has to overcome stiction before it can react. A rubber bladder does not "know" friction and reacts smoother and faster to pressure changes."
