It"s a pity that the Avikan racing gate - fast and slow - work only with the Keff, Blink Keff and Veronas Sparrow, but not with every other hoverbikes in the game (vanilla or modded).
However the normal racing gate, which is a proximity sensor for vehicles, work with any vehicle (the only problem is the time it stays activated, which is too short comparing to the normal proximity sensor).

Is there a way to fix that ? It would be cool to create some tracks with any hoverbikes and not only the ones from Elithian races. :)
