We have the solution for that. It is just not been installed yet. We are going to be using a mesh like metal, thing decorative diamond shaped holes. It will be on the lower front opening, and the upper rear opening behind my helmet. Than, a window net where I will be going in and out of the set. The lower rear opening is behind the seat completely. Is there a need for any barrier there? And the lowest part directly next to the seat, is under the structure of the seat as well. We may put a barrier there, but we are also adding one more bar on each side under the door bar from the rear "x" to the door bar. Just to complete the traditional "x" look. It won't be perfect, but we think it will be enough to not be haggled about.
