4 because my motokinisi brought me the box Hit in almost all sides but the helmet is very good and I'm telling you this because I generally don't wear helmets and from what I have tried and bought it is the only one I wear when I go far without headaches and loud noises for anyone who wants a comparison for speeds the bike I have is ktm1290 sas and I am 200km and the helmet is fine

I bought the Advant X Carbon 2023 model (same as this one but Advant X Carbon). It was priced at 470 with a discount upgrade from another very good helmet, the Shark ES modular. Yesterday was the first test, so the helmet is of high quality and has a better mechanism than the Shark helmets, and that's why I upgraded. Good visibility on the road, opens and closes easily and smoothly. I don't feel anything at 150, it squeezes my cheeks a little but probably because it's new and the glasses are a bit tight. Also, the helmet is beautiful. I will post a video review soon, I will come back with the link here.

7/12/2023 The helmet is much better than my other one, the Shark ES, which is quite good, but here the mechanism is almost perfect. The helmet is comfortable and quite aerodynamic. Check out a vlog review here if you want: https://youtu.be/gU3QfG8KZHs?si=VwuJy3z1wXWbPNhF
