I am a statistician.
helmets reduce fatalititestosteronehopping 41%. They redseverity juries by nearly the same amount.
white helmets reduce fatalities by an additional 24%.
This means that a motorcyclist wearing a white helmet has about a 55% less chance of a fatality than one not wearing a helmet at all.
Yes this is true. It was first studied in New Zealand in a ten year study of bike colors, clothing colors, and helmet colors. This was a very well done study (yes I did read it in its entirity). This study showed that clothing color or bike color did not matter in either crash or fatality statistics. Only helmet color mattered and white reflective helmets reduced fatalities by 24%.
Subsequently a similar study was conducted in Europe. This second study occurred in France and Germany primarily. There were a few Italian data points and a few from UK. But not enough data from outside of France and Germany to make a difference. This was just as well for the Italian data because the motorcycle driving laws do not provide credibility to any Italian based data.
I was consulting on the European study and found the study to be fairly credible. The study had a couple of problems. For one, it did not differentiate between "quality" helmets (for us that would be DOT approved) and low quality helmets. The European study showed between a 24% and a 33% fatality reduction for white helmets. Unfortunately, the investigators did not develop a rider assessment. As a result, they were unable to determine if the observed life-years saved were solely due to white helmets, or whether people who wore white helmets we just more safety minded. I spoke with them about this three or four times, but they claimed that they did not have funding for the additional analysis.
Consequently, I always use the lower number of 24% reduction.
Clearly there are differences between motorcycle driving in New Zealand or Europe and here. However, with a number as large as 24% I am doubtful whether an American based study would result in a significantly lower statistic. What I mean is, even if the statistic was off by 50% it would still be very significant, and should not be ignored.
I tried to develop numbers for trikes (3 wheel motorcycles). However there are too few 3 wheel motorcycle fatalities to be able to make any scientific statements. It is good that in 2011 there were only six deaths on 3 wheel motorcycles. However the lack of data points prevents any science-based statements regarding trikes or Spyders.
Your arguments against wearing a helmet do not have any evidence in support. The arguments are at best anecdotal and are rife with belief.While you are quoting stats, what stats show the years of riding experience? I don't always wear a helmet, in SC it is a personal choice, but I see these younger sports bike riders, full face helmets with video cameras on top of the helmet, I see them burning off their tires, slinging rubber hither and yon. Running their tach's up around 10 grand before hitting their shifter.
They NEED a helmet, and they NEED to fill it with brains, instead of testosterone! I've survived with and without a helmet, but never felt the need to videotape my ability to be stupid! I've got 55 years riding experience, from little scooters and minibikes, to dressers, Vespas, Hondas, Harleys, 2 strokers, even an old Indian. But I have always driven 'like they are out to get you.' Because they probably are. When a helmet becomes a substitute for common sense, I'll take common sense, when bravado is a substitute for thinking defensively, I'll think safely. Stats can be made to say whatever position the person formulating the statistics wants to say. I've worked emergency departments on 3 continents, and I've seen 2 motorcycle wrecks where their helmets saved their lives but sheared their spinal cords, their lives revolve around letting students learn how to insert a catheter into their bladder because they are totally paralyzed and can't pee on their own. In their case, they wished they hadn't had their lives saved, they hit to upper door edge of the car that "didn't see them in the road", thanks but no thanks! They were different accidents in different seasons.

I noticed that not one single HD rider was wearing a helmet. It has been my experience that when I see someone on a HD, they are not wearing a helmet. Could someone please explain, is it an unwritten rule that if you ride a HD, you can't wear a helmet?
:roflblack::roflblack::roflblack::roflblack::roflblack::roflblack::roflblack::roflblack:Yep, It is a rule, When i bought my Two Harley's in order to learn the secret Harley wave' i had to promise not to wear a helmet..![]()
I didn't suggest that you shouldn't wear a helmet, my examples were not statistical, they were real patients, not anecdotal stats, their helmets were pressed backwards, rotating on the axis of their head, shearing their spinal cord. Both had less than 1 year riding experience. I could probably go to ABATE's website and pull up statistics to support my thesis, my point is that statistics don't drive cars and not look for motorcycles and a lack of experience is generally the primary cause of most of the motorcycle accidents that I've treated. Yes, I am using stats, but they are my personal experience stats. I've never been published, but I have reviewed my own past.Your arguments against wearing a helmet do not have any evidence in support. The arguments are at best anecdotal and are rife with belief.
Perhaps you could provide some published, reviewed, and non-feeling based evidence. That is the very least you could do--after all, that is what I did for you.

I've never seen one of ABATE's studies which were scientifically valid. If you know of any, please forward the citation to me.I didn't suggest that you shouldn't wear a helmet, my examples were not statistical, they were real patients, not anecdotal stats, their helmets were pressed backwards, rotating on the axis of their head, shearing their spinal cord.

I was at my dealer on Saturday to get my recall done on my RT-S. This dealer is primarily HD but they also have Can-Am and Suzuki. They were having a memorial ride for a club member. It was all HD and 1 Ninja. I noticed that not one single HD rider was wearing a helmet. It has been my experience that when I see someone on a HD, they are not wearing a helmet. Could someone please explain, is it an unwritten rule that if you ride a HD, you can't wear a helmet? I myself wear a half helmet when it's warmer and a full helmet with face shield when it's cooler. For just riding around town, I usually don't wear a helmet. My wife always wears a helmet, no matter where we're going. I'm not judging anyone. I just want to get some different viewpoints and opinions. Thank you.
But some of them wear those non-DOT approved novelty helmets....you see them--they look like old WWII German helmets. Then to make it even worse they stick things like spikes on the helmet. I guess denial is not just a river in Egypt.
