After both quit EnduroGP, a new series has been announced with top riders signed to both teams.
The WESS series intends to run a multi faceted series using a variety of disciplines, although most of the races are existing Hard Enduro Red Bull races. The intent is to mix hard enduro, traditional enduro, cross country and beach racing to determine a champion.

All of the races will run amateur events at the same time, which is a major factor in the teams making the move to get mass exposure with potential customers.
