I wonder how they do helmet testing, shoot a head out of a canon against a wall? lolHelmets, like everything else in the motorcycle world, come down to the level of risk you're willing to take. I have a $210 HJC IS-MAX helmet that had the features I wanted and happened to fit great with thicker cheek pads. The more you pay, the more technologies you're typically getting. Some of the helmets use shells that destroy themselves on impact, much like modern cars, to dispate the energy of a blow; others use just a polycarbonate shell that bends and directs the force over a larger area to lessen the impact. Below that you find different foam materials that crush at differed rates and different ways to further dampen the impact force.
That said, I'm reasonably confident a lesser helmet will protect a person's head in most crash situations the average rider faces. As speeds increase, however, the more force your noggin might potentially sustain. That said, it never hurts to have more protection.
As for Snell versus DOT, that's a mixed bag. Snell does have higher standards, but it's also a racing standard. It's named for a racer, Peter Snell, who died when his helmet split in half. I've seen lately that they've begun specializing now between types of sports the helmets are for (e.g. Automotive) and limit the tests. A Snell rated helmet for automotive won't necessarily be tested for abrassion resistance, but be fire retardant. The motorcycle ones won't be fire retardant, but abrasion resistant.
Also, as someone said earlier, it means they meet or exceed the standards, so it is quite possible that a DOT helmet exceeds the Snell standards, they just didn't pay for the Snell testing.
It's all things to consider in helmet selection. I passed on the G-MAX helmets because even picking them up, they just felt like they were poorly made.
Actually it's done with weights dropped from specified heights and they measure the shock transferred to dummy heads inside as well as the deflection and deformation of the foam inside the helmet. Pretty much any helmet should be replaced the first time it hits the ground with a head inside it. It's actually a myth that even if you drop the helmet on the ground it needs to be replaced. If your head isn't in it, the shell will act like a spring when it hits the ground and it won't damage the inner foam which is the majority of the impact protection. But if your head is in the helmet when it hits the ground, that energy will go through the shell, into the protective foam which will deform to protect your head. Once that foam is deformed, the helmet is done.I wonder how they do helmet testing, shoot a head out of a canon against a wall? lol
That is my favorite helmet, but in red (in case you don't know who is Kiyonari... [ame=http://www.youtube.com/watch?v=KycZk1M7g24]SBK 2008 - Donington Park - Kiyonari Show - YouTube[/ame]). Also design wise I would like to be able to pick up a RF-1100 Conqueror, Red.....Might upgrade I technically have 7 days
:spank::spank::spank: Might shoot for the x twelve
My buddy at work runs with the IS-16 Scratch in red. It's a sweet looking helmet.the HJC IS-16 is simply a fantastic helmet, imo... and, i absolutely love mine! before buying it i also tried the Scorpion EXO-1000, but it was difficult to get on/ off, it was heavy, and it also didn't fit the shape of my head that well. sadly, the HJC IS-16 Scratch graphic is now discontinued. so, i looked online and found a close-out deal on it last week. and, i bought an extra one- just in case i drop mine or damage it. <lol> (a nosey kid at the griffith observatory almost pushed my helmet off the table onto the ground.) the new IS-16 graphic that they have looks too weirded out to me.
That helmet looks amazing, I'd love to get one even just to make a Master Cheif halloween costume. Haha.I just spent $399 on my AGV AX-8. And I don't even have a bike yet! lol
