The ergonomically formed mouthpiece lies perfectly in the horse's mouth resulting in soft and even pressure on the entire tongue area, encouraging the horse to chew. In addition, this bit supports the contact to the corners of the mouth in a very effective way, keeping the horse on the bit. The gentle joint in the middle which is angled forward - the characteristic feature of the KK ULTRA - and the fine eggbutt design makes it a very friendly bit. The mouthpiece is made of AURIGAN, the material that activates the chewing activity of your horse. The new DYNAMIC RS bit gives soft but very effective instructions for a better contact between horse and rider. 70mm flat stainless steel rings. 16mm thickness.
