New Snell ratings?

[C. Ludwig]

Anyone know when the SN05 helmets will be available? Or are they already?

I'm reasonably certain that the helmets should go on sale about mid-October. I think the SA05 spec was released to begin testing in August and manufacturers were not allowed to start selling 05's until mid October.

Remember, SA95 helmets can be used through 06 (they are no longer accepted after 1/1/07).

Thanks. I did think this was the last year for the 95s. I'll be looking for a new one anyway. Thanks Bill!

There was a GREAT article in a motorcycle magazine about the relationship of the helmets rating, and it's actual effectiveness in an impact.

The net net on it was that you might want to think seriously about what the statistical liklihood of your potential crashes is, and buy accordingly.

I will try to locate it. I can scan it if anyone is interested. If I had read this before I bought, I might have done things differently.

Found it. it is Motorcyclist, June 05.

I wonder if Baker has read this and what he thinks.....

Since I won't bother to find the article and read it can you fill me in on your take?

Negative.

I dindt bother waiting, knowing how badly I sweat out a helmet I will be lucky to get 5 years on my new helmet. My last one was only 3 years old and already wasnt good for more then autocross use. and I only used to for 3 years of AX and a few track days.

Using a balaclava helps to keep your helmet a bit fresher b/c you sweat into the balaclava instead of into your helmet liner. I recently started wearing a balaclava with my antique SA95 helmet - let's just say that the odors are less than before but it's like wearing a miniature oven on my head...

I've read it and the Synopsis is....

Increasing energy requirements make the helmts stiffer than they really need to be resulting in higher gee loadings. Their example a dot certified helmet might deliver an average of 198 while a hard Snell 00 fiberglass might be up around 235 average. The main arguement is that Snell should also work on reducing gee loadings in addition to higher energy. I think the 05 rating is done for two hits that would pass the 00 rating. Fancy fiberglass helmets that claim delamination as a way to reduce gee loads don't work. Also discussed was surviability of head trama and combined head and body trama with age related factors. A side point was that Snell has become a marketing tool and the periodic upgrades are simply to out mode the old equiptment.

ps. I'm in the market for a new helmet too, so I found this article :119:

I'm thinking about keeping it in the car so that it'll repel the mice...at least I'm not as bad as a certain former CRX driver who works for a local fabricator. He came into our shop to purchase a new helmet this year. Since he was purchasing an SA00 with the SA05 just around the corner, I had to ask "Why?". He was a bit coy about his response up to the point that his cat had been using it as a litterbox over the winter
:119: :119:

I have a cat myself but would have had to use restraint to keep from making Kung Pao Kitty out of him had that happened.

Out of curiosity, what does cat pee do to a Snell rating?

Note that the M helmets are different from ours. I think what the article is essentially saying is that helmets more like SA helmets would result in less injuries to motorcyclists. If you press on the shell of an M helmet and one of our helmets, you'll see the difference. My Simpson Voyager has a soft shell...you can really see it when you have to drill the holes for the Hans...it deforms if pressed hard. This is why you should discard it after any impact...the shell could look perfect but the foam inside will be deformed and you won't know it. So ours are designed for a single blunt impact. The M helmets are designed for multiple blunt impacts (like a curb). One other thing to do is to get the good rollcage padding, the hard BSR stuff, not the soft pipe covering that most people use.

Good point, one must remember this is written for a motorcycle publication. But I wonder that in some of the more violent crashes that the driver hit's their head on the same spot on the cage over and over. I actually think taking multiple hits is a good thing, but not at the expence of increased gee loads. The compairison between a foam hammer and a wooden mallet :bash_1_:

Don't know about cat pee, but I had a friend whose dog used him helmet as a barf bag while he went to dinner!
