There is currently no other neck protection system available for motorcyclists that can effectively help prevent all of the above potential injuries. The design rationale behind the Leatt-Brace(R) is to bring the head to a controlled stop. This is achieved by providing a padded rigid structure that acts as an alternative load path for neck forces. Helmet impacts otherwise transmitted from the helmet to skull and then to the neck are re-directed from the helmet to the brace to other body structures in a safe way. The design of the Leatt-Brace(R) prevents the helmet/head from projecting over the brace and therefore prevents a fulcrum action, which has been documented in literature pertaining to the use of collar devices. The Leatt-Brace(R) GPX Club works with most types of body armor and chest protectors. It is also suitable for use by Superbike riders. Over long distances, the Leatt-Brace(R) will also offer some relief from neck fatigue. Only leathers with a hump require minor modification. The X-Strap (for upright riding position) and GP-Strap (for Superbike leathers with a hump), included with the MOTO GPX, are designed for the extreme rider who may experience 'float' at high speed (Superbike) or in a big air and flat-out whoop situations (motocross). Note: Not all riders will find the X-Strap and the GP-Strap necessary. The Leatt-Brace(R) GPX Club is compatible with all motorcycle helmet types and our design allows riders an adequate range of movement. The Leatt-Brace(R) MOTO GPX is designed for use on all motorcycles and ATVs for competition use, recreational riding and daily commuting. Leatt-Brace(R) has been tested by BMW Munich, KTM Works Riders, the SABS (South African Bureau of Standards). It is also endorsed by MSA (Motorsport South Africa).
