this one is $300 retail, 4 star crash rating, DOT and EC approved (sunvisors and quick strap exclude snell). AGV has some that are 3 star. My scorpion is 4 star with lower forehead hit score.
I tried on A LOT of helmets. Only a few models fit adequately. I also ride bicycles those helmets that are all styrofoam and a hand ripable cover of lexan.
