I have (had!) a helmet with one of those internal sun visors that slide down when you want it and slide back inside the helmet when you don't. From a utility point of view it was great.

Then the attached photo happened in what I perceieved to be a "small off", low side, with no marks on the outside of the helmet at all.

The crack goes right through and if I were to provide a bit more thumb pressure there I think the whole forehead section would snap off. Fairly clearly the helmet is a write off like that, I guess that's why we buy them, but for such a small impact it seems a bad way to fail.

It seems that the gap between the foam and the shell where the visor slides in and out - about 15mm at the widest, means that there is nothing to stop the foam breaking at that point. In a larger impact I could imagine the foam could have fully broken forward giving the helmet an instant 15mm or more of play in which to move about on your head.

What does everybody else think?

I really liked the internal visor, I REALLY liked it, but...

I was looking at a HJC that does that last weekend. I had a look online and notice that it only has a DOT rating not DOT/Snell. Now I know there is a big argument about ratings and helmets but it made me wonder....... (he he now I have that Led Zep tune going through my mind ohhhhh she makes me wonder).

The one I pictured above meets (so they say) ECE 22.05, same as this (and bought from same place)

I would not be at all impressed if that happened to my helmet.

Get a flip up one next (Nolan N103), they're great.

Thats a valid point you raise about supportwhere the insert dark visor recesses. I have a shuberth with that system and I am happy with it, but from now will keep a close watch on that area.

Tks for posting

Both Snell and DOT are pointless. if it is ECE22.05 you're all good. Comparatively.

looks like a Nolan to me....

How does the N103 handle the gap where the internal visor goes though, is there support for the foam in that area?

Check out the Sharp standard rating for your helmet.

http://sharp.direct.gov.uk/

Site is a bit loopy but you can compare different models of helmet to each other where results come from actual impact testing.

except that some brilliant helmets which are known to be fantastic get poor ratings....example arais rx7 corsair.

Until they release details in their testing process, it firmily goes into the bullshit category.

I'm sure that'll buff out.
If it doesn't a bit of tape will cover it up OK.

Oh - and the lyrics are "...and it makes me wonder."

It's not rated by Sharp last time I looked unfortunately.

Marks to cnell (S & S Products), got an email today from them simply asking me to send it back for replacement.

I'm still undecided about the internal-visor design of helmets though. Some "recognisably named" manufacturers seem to be coming out with them, and I've read of people also feeling unsure about similar things, but that testing shows that it doesn't make much difference. Of course, all tests have flaws :-/

I'm beginning to conclude that it's a tradeoff. Having an internal visor makes it a little less secure in the forehead region (with the helmets I've seen) so it might be a little less safe in certain types of crashes.

But equally the internal visor may help prevent some crashes because you've always that shade there when you need it, and not when you don't, meaning your ability to see is probably improved on average.

Sharp isn't a standard.

It's an ABS plastic helmet. That is probably quite a good result.


The reason Arai eg doesn't rate well in sharp is because it uses variable density materials.

Thicker at highest likelihood impact points - thinner at lower likelihood.

Sharp rating impacts them the same all over the helmet.

I have a Caberg, purchased in the UK & it has saved my bacon a few times going from sunny to dark. I would trade off any safety doubts against better visibility every time. Ever seen what happens to sunglasses in an accident? It's not pretty.:woohoo:

I find the Interal Visor in my Givi helmet to be invaluable.
Wouldn't buy another helmet for everyday use that didn't have one.

I don't think the gap for the visor is a significant safety issue. Much rather have the ability to flick down the visor and see where I'm going - or flick it up when the skies darken.

The other day a workmate crashed into a parked car (he was in his car not on a bike) because of sunstrike.
Silly bugger tried putting on his sunglasses rather than pulling down his sunvisor. By the time he had them in his hand he'd collected the back end of a VW.
