I also need some helmet buying advice. In 2015 I may be running a laydown enduro so I don’t think my HJC AR-10 will do the job, aero wise. It hasn’t done me any favors in my laydown sprint kart. Would a motorcycle be any better or worse? I’m looking at the Bell Revolver Evo right now. The price is really good also. My only concern would be the chin area as your head is forced down in an enduro kart.
