Thank for the review. I crashed in a AGV k5s. I use to have HJC Helmets I went away from them because they fogged up way to much. I had the CL 17, and I had the CS r3 helmet. Surprisingly the CSr3 helmet was way better than the CL17. After those Helmets I went to scorpion exo r2000 helmet and my back up was a Vendetta 3 helmet which is now owned by Fly Helmets 1 with a drop down visor. I own a bussa now and it's hard to find a stable helmet at about 150-180mph on my busss. I saw this helmet and was wondering about fog, stability, does it have a chin guard, and how much air flows through it while they are closed and open and how far from the ears are the speaker pockets? By the way I use to own a 2008 Yamaha FZ1, I sold it for the bussa.
