Hey guys and girls just purchased a new helmet, the scorpion exo st1400 carbon. This thing is a shiny carbon fiber 4 pound something with drop down visor and got to say looks great, feels great, light, aerodynamic and not too bad for noise too. Honestly I think we should ride with ear plugs, but this is not too bad. My head is 56.5 and a med fits just tight enough. Paid $507 can all in on amazon and personally i think it's a nice bang gor the buck. Not wanting to criticize the shoie snd arai followers. Hope it gave good info that someone can use.
