    The old argument is that the MX helmets may not protect you as well in low speed crashes. And of course, ventilation is pretty poor sometimes. And I guess weight comes into play too.

    They're fine as far as protection, but they're hot as hell and heavy.

    motorcross helmets are usually going to be heavier but thats besides they have higher crash standards then a full face bicycle helmet like a giro mad max or a troy lee d2. Not all motocross helmets are going to have poor ventilation, like many people say, you get what you pay for.
    Just ride.....

    Until someone starts selling replacement brains I am going to stick with moto helmets.

    I started using a moto helmet this past year and didn't notice any big difference. The difference that you will feel go away after a day of using it.

    Good job! Motocross

    I use an Arai motocross helmet, for shuttle days at Diablo. I like my brain in my skull so I went with the best I could find.

    I have an Answer M8 when they were DOT certified and love it. I have cracked three helmets before this one and the extra protection is well worth any extra wieght and ventilation issues. I wear mine for BMX racing DH and riding trails back to Dirt jumps and stunts and I feel it's crazy to do this stuff without it or a lesser helmet. I kinda need my brain for work and stuff.

    Ofcourse moto helmets are better.. for high speed
    their higher weight is good for a high speed crash, where you need the extra padding and protection, but when going at a low speed (10-15mph orso), the weight throws your head around so much more than a light mtb helmet, and may cause neck damage or whatnot

    My HJC carbon is lighter than my D2, and moto helmet on any situation offers more protection than your regular full MTB helmet. More protection is all ways better.

    ..common dude, use some common sence. somthing our country seems to lack...

    It's not very complicated. Helmets consist basically of two parts, an outer hard shell and some sort of foam designed to absorb the force of the impact. In a helmet designed for high speed impacts, this foam is going to be very dense and firm, so that when you hit a brick wall at 60 mph, it can absorb the force from the impact. Conversely, a bicycle helmet is going to be made of a a much less dense, softer foam that will protect you from small falls etc. Now, if you were to wear a helmet designed for high speed impacts, and suffer a low speed impact, the foam in the helmet is not going to give very much, because it is designed for high speed crashes. This means that you won't be very well protected. Bicycle helmets are designed to offer maximum protection at bike speeds, motocross helmets are designed to offer maximum protection at motocross speeds.

    Oh, and another thing our country seems to lack is the ability to spell simple words.

    Well said. I was hoping that other people would realize that, but apparently it is not I that lacks common sense.

    Thats a silly argument.

    The fact is the MTB helmets offer nowhere near the protection of MX. The styrene density and overall design do of an MTB helmet do not provide a safer helmet for 'low speed' crashes - this is as risiculous a supposition as "Marlboro lights cause sterility. Besides, if I were going slow - I likely wouldnt be needing the fullface.



    Weight shouldnt be a huge factor - a decent helmet should be 2.5-3lbs regardless.

    ventilation can be an issue as MX riders are going alot faster in general - ventialation designed accordingly.

    That said - I will never wear an MTB specific full-face. Must be DOT and Snell certified or F-it...

    The reason I went with Motocross

    My motocross helmet is SNELL M2005 certified. So are all my street bike helmets. I basically only wear Arai mostly because how well they fit my head. And if you talk to any helmet manufacturer they will tell you how well a helmet fits your head directly correlates to how well it will protect your noggin.

    I don't think we can lump all motocross helmets as one standard and all bike helmets in another. Different manufacturers make different helmets to different standards.

    It is my understanding that SNELL rated Motocycle helmets are tested to higher standards and will theroeticly protect you from higher velocity hits.

    Also don't base your decision on what some guy on the Web says, base it on facts and not everything said on a Bulletin board is fact.

    I think before you go out and buy a helmet you find out what standards that helmet has
    been tested too and also what you feel your head is worth to you.

    http://www.helmets.org/standard.htm

    http://www.smf.org/stds.html

    I would start there and find out the real facts.

    just my two cents.

    If you are just doing DH with shuttles then your good, other wise riding with a motorcross helmet is like sticking your head in a fish bowl.

    Hmm, Its hard for me to consider that common sense. I really don't think the average common folk usually think about the density of the foam inside their helmets

    Alright, then go by what the first link says, under information about Snell. "Some helmet experts feel that the resultant helmets [ones designed for the highest impact testing] are usually too stiff in impact response to perform at higher drop levels, and may well offer less benefit at lower impact levels where the stiffer foam may not crush at all."

    Basically what I said.

    I use a moto helmet for downhill because on many downhill courses you can reach motocross speeds. For freeriding and pedaling uphill I use a bicycle DH fullface helmet so my head doesn't overheat.
