i'm new to this here helmet game since coming from a turtle shell off a harley. this is what i've learned so far:
1. helmets WILL expand a little with wear, they will "break in".
1a) different manufacturers, and different models within have different outer
shell shapes for different shaped heads. you want a snug fit ALL around.
i am selling all 3 of my helmets because if this. i had a shoei X-11 [sold], a scorpio exo-700 [sold], and a nitro 800 [available, ad in classifieds section of org.].
2. check for features:
2a) proper venting to cool you off in summer.
2b) light weight.
2c) aerodynamics of helmet.
2e) wide screen opening for better vision.
2f) screen that blocks suns rays so you dont get burnt while riding.
2g) screen that shuts tight or locks shut.
2h) screen with anti fog.
2i) screen that stays open a fraction of an inch for extra cooling in summer.
2j) fully removeable and washable interior.
2k) different size cheek pads for custom fit.
3. legal and safety ratings, dot, and snell raitings, also good are ece [european
standards], acu gold [british?], and i believe there's another one....british?
bsi?
if i missed something chime in.
