If they both fit perfectly well and you have no issue with the cost of either helmet then go for the one with the features you like. I have the Shark lid you are looking at and I must say that the internal sun visor has been incredibly useful, especially at this time of year. The downside to it is that it doesn't fit my nose properly so I had to modify it a little. On the other hand a pinlock insert is easy to fit if the posts are already on the visor.
If you really can't choose between the two, buy the one with the design that you like ____________________ Theory test - 19/8/09, CBT - 11/10/09, MOD 1 - 16/8/10, MOD 2 - 27/10/10

Without pictures or knowing how they would fit.
It would be the Shark for me

Get the one that fits you best mate.
I'd be getting the one that felt the best and 'tighter' out of the two.
Then go onto features and gizmo's.
I have a Shoei-XR1100, without a sun visor. This is hardly a 'con' because you can get dark / smoked visors for when it's sunny. Personally I don't even think twice about using one. Just saying incase you didn't know these are available!

Thermoplastic versus tungsten carbide fibreglass is a non issue according to this study, which also notes that in practice, helmets that are only Snell rated are the least protective.
ECE (275g) and DOT (400g peak but practically 250g) are both stricter than BSI/Snell (300g).

Sadly, that. And you'll only find that out when you flip it down, i.e. exactly when you need it most. Found that one out this morning.
We need a pinlock for sun visors... ____________________ Biking is 1/20th as dangerous as horse riding.

I have also heard that the sun visor can mist up but I imagine you would have the same issue sunglasses ?
The alternative is two visors but that is a pain, particularly in winter when the ride to work can be sunny but the ride home dark !
In the summer, you might be able to get away with one I guess |

By who, and on what basis?
Genuine question, since "fibreglass" can be (re-enforced) thermoplastic. |
The manufacturers themselves for one, and also the Snell Foundation:
"Like most major helmet manufacturers, Arai subscribes to the Snell Memorial Foundation benchmark of five years as the suggested usable lifespan of a motorcycle helmet. Why? Think of a helmet in terms of your body. No matter how good it may look, or how well you take care of it, age still takes its toll. Even with minimal use, a helmet is affected by things like the acids and oils in sweat, haircare products, pollution, exposure to UV rays, etc. At about the five-year mark, helmet interiors begin to show wear and/or deterioration, which should serve as an alert to its overall condition. The helmet's fit may begin to feel a little "loose", not as snug as it once did. This unseen aging and deterioration of the EPS liner and fiberglass shell can affect the helmet's ability to perform in an impact as it was originally designed. If a helmet suffers an impact and any doubt exists as to its further ability to protect, it should either be returned to the manufacturer for competent inspection or discarded and replaced.
These are the reasons to replace your helmet after five years. Of course, if your helmet becomes less than snug in fit, or damaged, it should be replaced before the five year mark. And when you do, you may want to remember that Arai was the first company willing to warranty its helmets for the full Snell-recommended usable lifespan."
Thermoplastics suffer more from UV degradation so the lifespan drops to 3 years.
You should of been told this on your CBT also as it is what the DSA teach us at Cardington to pass on to the trainees.
Do what you like, ignore the lifespan if you want because at the end of the day it is your head and brain, not mine. I don't wear thermoplastic lids and i replace them every 5 years or sooner. ____________________ stinkwheel: He had an animated .gif of a cat performing fellatio. It's not socially acceptable.

Perhaps I was unclear. I'm specifically interested in this issue:
Matt B wrote: | Thermoplastics suffer more from UV degradation so the lifespan drops to 3 years. |
Helmet manufacturers have a vested interest in encouraging replacement, and in market segmentation to give reasons to buy their more expensive helmets.
Snell do indeed recommend 5 years, but I can't find one word about 3 years for pure thermoplastic shells. Nor can I find anything at SHARP, nor the US Department of Transportation, nor in the Shoei, Arai or Shark FAQs. Where should I be looking?
By the way, when you buy a GRP lid, do you check what sort of P it is? Are you sure it's not the same thermoplastic as in a non glass-fibre lid? Why?
Matt B wrote: | You should of been told this on your CBT also as it is what the DSA teach us at Cardington to pass on to the trainees. |
I've been told a lot of stuff by a lot of people over the years. Much of it has turned out to be apocryphal.
I did replace my helmet after 3 years, but I'm not entirely sure why. ____________________ Biking is 1/20th as dangerous as horse riding.

Hey, for what it's worth I tried on several helmets at Infinity in London and found the Caberg Ego to be a good fit for me.. £114, has the good safety rating, the sun visor, pinlock etc. And comes in a nice Matt Black finish..

True, but as manufacturers of safety equipment they also have a duty to inform customers of the lifespan of the product so we know that the item is as safe as possible. If manufacturers failed to state or overstated the lifespan then I'm sure any fatal injuries sustained wearing an old helmet could result in litigation.
Rogerborg wrote: | Where should I be looking? |
In the FAQs on the manufacturers websites, or email them and ask if you really want to know what they say. TBH you can take the advice or not, end of the day it is not my brain in danger.
https://www.smf.org/helmetfaq#aWhyReplace
https://www.araiamericas.com/support.asp?page=support/warranty.asp
https://www.agv.com/us/faqs
Snell have been testing helmets for over 50 years, if they say 5 years lifespan then I'm happy to go along with that. SHARP have no real interest in lifespans, they test impacts and that's all, however even they quote 3-5 years.

I don't buy plastic lids so I can't answer that. I use AGV, and my current road one (due to be replaced soon) is an S-4. It's shell is Fibreglass and Kevlar ACF2 (Advanced Composite Fibre ) and was built with varying shell sizes. They are smaller and lighter than plastic therefore more comfortable and less strain on the neck. ____________________ stinkwheel: He had an animated .gif of a cat performing fellatio.

Hi
I have a Shark S900 Enigma (black and white)
Brilliant helmet from the crappy duchini I used to have, pros and cons:
Brilliant anti fogging - Never had it mist up once on a cold day EXCEPT for in the freezing fog, where it started to form ice, but that's unavoidable really
Also the integral sun visor isnt anti fogging at all, have it down and exhale and it will fog right up BUT
Its so well ventilated that it takes any fogging away instantly
BUT
It's so well ventilated that the wind noise is really bad! At 50-60 on a windy day I can't hear myself on the red line. Also cold as fuck because it sweeps wind all in the helmet and around it so I find without a scarf or something your face gets freezing, i've tried playing with the vents on the forehead and mouth, closed, opened, closed while riding, make no difference however they are done, still freezing wind pouring in.
Very comfortable though.
Sun visor is brilliantly useful, although when the suns low and bright it doesnt completely take the edge of, although it's much better than just having a normal visor definitely. I often have the visor up and the sun visor down and ride around like that
Great quick release strap, had it a few months now not worn down or anything and very easy to get on and off even with gloves on, couldnt stand the double D straps.
Didn't know about pumping up cheekpads, lol wut? Maybe not on the enigma version?
Also thought I had a big head, last helmet was medium, had to get a small size for the shark to fit
So be wary if you're buying online

With respect, Matt, your helmet is glass-and-kevlar-fibre re-enforced plastic. I'm not sure why you'd be confident that the plastic matrix isn't subject to UV degradation.
None of those links make any distinction between thermoplastic shells and any other sort, and I'm as yet unable to find any that do.
Fair enough though, there is a fair amount of documentation of UV degradation of some unstabilised thermoplastics outwith the context of motorcycle helmets, and there's doesn't appear to be anything in any helmet testing regime that tests for it.
To be clear, I'm not arguing against the sense of replacing every 3 years, but it's more because of a lack of information, and that bugs me. ____________________ Biking is 1/20th as dangerous as horse riding.

Thanks for taking the time to provide your view on the S900. That was really helpful.
As regards the cheek pump, I think that is only in the newer 2012 version, the S900C. |
