Sprenger KK Ultra – Aurigan Rings


  • KK-ULTRA Bits take advantage of the exceptional sensitivity of the tongue.
  • Adapted to the anatomy of the horse’s mouth.
  • No pressure put on the palate.
  • Clear instructions given as the tongue’s sense of touch is utilised.



SENSOGAN® is a new bit material developed by SPRENGER and is the result of two years of research and development aiming to improve on the AURIGAN material which has made SPRENGER bits so popular with so many professional and amateur riders.

SENSOGAN® has improved properties but also a new appearance. The white-gold colour gives the bit a discreet and elegant look and due to the improved material mix, SENSOGAN® does not tarnish easily as the chewing activity of the horse is optimally supported. The bit will stay true to its white gold colour for much longer and can also be polished to a high shine at any point in its lifetime. The new SENSOGAN® range is identified by its unique stamped black ring on the cheeks of the mouthpieces.


The special challenge in developing SENSOGAN® was to maintain the positive features of Aurigan yet to intensify them, giving an even more delicate and sophisticated connection to the horse. In the twenty or so years that Aurigan has been available, many companies have copied its colour but never its properties. Sprenger knew the time was right to launch their new optimal bitting collection with an unmatched look anywhere else in the market.




It is the distinctive composition of Copper, Manganese and Zinc that makes SENSOGAN® so special. The reduced copper content combined with the manganese results in a more regulated process of oxidation. Tests with the veterinary college of Hannover and the German Riding School in Warendorf  showed without doubt this combination of metals has a positive influence on the horses satisfaction, motivation and willingness to perform.


Manganese is known to assist with building up connective tissue as well as for muscle and energy metabolism, it is also known to reduce histamine and can help prevent skin reactions. The feed industry has recently recognised manganese as an important feed additive for competition horses.


Available in a wide range of the popular bit styles and sizes from Sprenger including the KK Ultra, Dynamic RS, WH Ultra and Turnado ranges, plus many other individual weymouths, bradoons and jumping and training bits. Different bit rings can also be ordered to match stainless steel or bronze coloured bridle work.





About the KK Ultra Mouthpiece


The KK ULTRA bits take
advantage of the exceptional sensitivity of the tongue. Did you know
that because the tongue is extremely sensitive it multiplies perceptions
in this area dramatically?

You might also recognize the feeling if the human tongue finds a
little how in the tooth it gives the impression there is a huge gap. A
horses tongue works in much the same way, whilst eating it can filter
out small stones from the food. In collaboration with SPRENGER, the
Veterinary University in Hanover started a new project. They examined
more that 70 horses heads and used various methods to take

The analysis of this information produced unexpected results:


  • The interior of the volume of the mouth was less than had been previously thought
  • The palate was both smaller and very often flatter than previously imagined
  • The space left for a bit is therefore very limited





SPRENGER used this new information for the development of the KK ULTRA. The aim was to improve the bits bit not make them too



How can the sense of touch be stimulated to obtain the desired effect?


  1. As the palate is narrower than originally assumed the lozenge in the centre was shortened (no pressure on the palate).
  2. The angle of the link was turned at 45. This ensures that when the
    reins are pulled the rounded link rests fully in the tongue without
    squeezing it.
  3. The tongues sense of touch is utilised and clear instructions are given through the reins.





Important Information


Make sure the bit is fitted correctly in the mouth. The arrow must always be on the left hand side pointing forwards.
