Safe System. The design of the insulated air chambers makes it impossible for air to escape.
Easy Handling. It only takes a couple of minutes to adjust the WP AER 48 to the rider's specifications such as weight, track conditions or riding style.
Lightweight Construction. Weight saving: approximately 1.4 kg.
The best of both worlds
A combination of hydraulic damping and pneumatic suspension unites the advantages of both technologies. Hydraulic damping enables the manual adjustment of compression damping and rebound damping. Pneumatic suspension saves weight and makes it easier to adjust the system to the rider's preferences.

Easy Handling. It only takes a couple of minutes to adjust the WP AER 48 to the rider's specifications such as weight, track conditions or riding style. Simply reduce or increase the fork pressure – all with a simple hand movement. A single valve is all it takes to adjust the pressure of the WP AER 48.
Lightweight Construction. Weight saving: approximately 1.4 kg. This equates to valuable seconds during the race and much lighter handling. Its well thought-out design makes the WP AER 48 especially low-maintenance.
Safe System. The design of the insulated air chambers makes it impossible for air to escape. The forks retain their shock absorbing function even in the unlikely event of a malfunction.
The WP AER 48 is a set of split-system forks consisting of an air suspension unit and a hydraulic damping unit. The forks are suitable for motocross models of all brands. The system is characterized by the ease with which the air suspension system is adjusted to the rider's weight and riding style and the specific features of the track or route. The WP AER 48 offers an average weight reduction of 1.4 kg in comparison to conventional fork systems. The compression and rebound stage also features an integrated and fully adjustable damping unit. The forks are extremely responsive thanks to friction-optimized surface coating on the outer and inner tube surfaces and optimally designed sealing systems.
