Double jointed mouthpiece, where the olive shaped centerpiece is shortened and inclined forward at a 45° angle. Only at this angle is the centerpiece particularly soft on the tongue. These bits therefore allow for a familiar, leaning and very fine reins. 
The innovative KK Ultra bits use the sense of touch of the tongue, which is as sensitive for horses as it is for humans.
The tongue is a very sensitive organ and amplifies the reception of signals coming from the rider's reins into the horse's mouth. When the reins are tightened, the midsection of the KK Ultra prostheses fits precisely on the tongue, without pinching and putting pressure on the palate. The connecting rings with the center roll over the tongue. Because of the new position of the middle and lateral parts of the dentition, the tactile sensation of the tongue is increasingly addressed. The rein aids of the rider land more accurately and sensitively in the horse's mouth. The KK Ultra bits offer an incomparably sensitive contact between rider and horse. When switching to a KK Ultra bit, an immediate improvement in alignment is usually recognizable.
