KK-Ultra bits take advantage of the exceptional sensitivity of the tongue.
-As the palate is narrower than originally assumed the lozenge in the centre was shortened (this results in no pressure being put on the palate).
-The angle of the link was twisted by 45°. This ensures that, when a contact is taken up via the reins, the rounded link rests fully on the tongue without squeezing it.
-In short, the sense of touch in the tongue is utilized and not abused, enabling clear instructions to be given through the reins.
