The Leatt-Brace™ is an injection produced glass reinforced nylon or carbon fiber and Kevlar neck brace system designed by medical professionals and motorcycle enthusiasts to help prevent:
 

• Hyperflexion: extreme forward head movement
• Hyperextension: extreme rearward head movement
• Lateral Hyperflexion: extreme sideways head movement
• Axial loading: compression of the spinal column due to the effect of force on the helmet
• Posterior hypertranslation: rearward movement of the head/helmet on the neck.

The design of the Leatt-Brace™ 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™ MOTO GPX 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™ 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™ MOTO GPX is compatible with all motorcycle helmet types and our design allows riders an adequate range of movement. The Leatt-Brace™ MOTO GPX is designed for use on all motorcycles and ATVs for competition use, recreational riding and daily commuting. The Leatt-Brace™ 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).
