Leatt STX Road Neck Brace
Neck injuries can be of the most serious upper body injuries in motorcycle road accidents. Leatt® STX Road, the all-new neck brace for street motorcycle riders, forms an essential part of your personal safety system. It functions in conjunction with your helmet and is designed to help protect your neck from extreme movements and overall neck loading in the event of an accident. The Leatt® STX Road is engineered with Leatt®’s proven Alternative Load Path Technology™ (ALPT™) and features seamless integration of function, movement and looks for street motorcycle riding, on the road or at the track.
Features of the Leatt STX Road Neck Brace include:
How does the Leatt STX Road Neck Brace Work?
In a typical face-plant type accident without a Leatt-Brace®, the force of the impact is transferred from the ground to the helmet, through the helmet to the scull and scull base where it is then transferred through the neck to the back (thoracic spine). With the Leatt-Brace® fitted, the force will instead transfer from the ground to the helmet, through the helmet onto the Leatt-Brace® once contact is made, some of the force will therefore be transferred to the brace and dispersed to the less vulnerable parts of the torso. If the impact is significant enough, the brace is designed to fail in crumple zones (similar to those seen in cars), thereby helping to absorb some of the energy of the impact.
What dynamics does the Leatt STX Road Neck Brace help protect against?
The Leatt-Brace® helps protect against the following main scenarios:

Thoracic Strut
Positioned at the rear of the Leatt-Brace®, between the shoulder blades, on the para-spinal muscles surrounding your spine (and not the actual spine itself), the primary function of the thoracic (pronounced “thor-as-sick”) member/strut is to stop the brace rotating backwards in a crash. But that’s not all it’s been designed to do, in fact like a crumple zone in a car, the strut has been engineered to give way under certain stresses and absorb some of the forces associated with certain impact scenarios.
It’s made from a carbon fiber/woven Kevlar® compound, that bends without shattering, the strut is designed to break at approximately a third of the force that would otherwise be required injure your back.
Several prototypes have resulted in the optimal strut size; big enough to help protect, but small enough not to restrict movement.
Anatomical Design
The Leatt-Brace® has been designed to ergonomically fit around you. The materials Leatt use are tested and certified safe.
In order for Leatt®’s Alternative Load Path Technology™ to perform at maximum potential, it’s necessary that your brace fits you properly. All Leatt-Braces® offer independent adjustability to ensure the best fit. This adjustability also means that it can be used in conjunction with various chest protectors and body armour.
Collarbone (clavicle) Cutout
A specially designed collarbone cut-out section on the Leatt-Brace® reduces contact potential with one of the most fragile bones in your body - the collarbone. It has been designed to accommodate the collarbone and allow for free movement of the arms without the collarbone coming into contact with the brace.
A small amount of force can cause a collarbone fracture, which is why these kinds of injuries are so common. It is also important to remember that the collarbone can be fractured in a number of ways – if, for example, the rider lands on an outstretched arm, where the force travels up the arm and into the collarbone, a fracture can potentially occur. In addition, a direct fall onto the shoulder and a helmet rim strike can also potentially produce such an injury.
While a Leatt-Brace® is not designed to help protect against these kinds of injuries, it does however help reduce the risk of injury to the collarbone by preventing the helmet from striking the collarbone.

Crumple Zones
Like a crumple zone in a car, all Leatt-Braces® are designed with integrated crumple zones to help absorb impact* energy and divert this energy away from the neck in part. Specifically, the rear upper member of the brace is designed to deform and give way in a controlled manner in an accident. Other crumple zones are also incorporated into the front member and strut design.Sizing Chart
