I took a little ride at Road A on Sunday and managed to let the rumble strip meet my new Arai. I'm more upset about my helmet than my bike... Either way, will this pass tech?
just thinking...if its good after the inspection, sell it to the squids but yeah probably a no go for tech...
That has been my understanding. I have a very similar Arai paperweight like that. I sometimes wear it on street rides since it's so much more comfortable. On the other hand, I have another helmet that took a tumble in a gravel trap. It only has light paint scratches and passed tech every time up until it's 5yr expiration.
The main purpose of a helmet it to expel the energy of an impact to reduce brain trauma. The foam inside can do that once. If the foam in your helmet has been compressed, it should be replaced. Seems to me that evaluating scratches and scrapes on a helmet is not a good measure of it's integrity. Take a belt sander to a brand new helmet, does that directly affect it's impact absorbtion potential? No. Indirectly? Possibly. Any damage to the outer skin can make it more susceptible to failure. However, is it likely that you will ever scrape all the way through the shell and then the foam to your bare head? Probably not. The original question though. Will it pass tech? Depends on the inspector and how deep his evaluation goes. A by the book black and white guy will see scratches in fiberglass and say no. Someone else who believes that it hasn't taken any impact may say OK. Is it a false start if you move in the box? How do you determine intent?
We can't tell about the internal structure easily - so we look at it and the outside and err on the side of not sending riders to the hospital. I don't care about intent with jump starts, what's that got to do with anything?
Personally, if there are any visible scuff (not light scratches) damage to the outer shell in the upper area (temple, forehead, back, etc.) I won't use it again. However, anything below that I would (ie. chin, lower jaw, lower cheek, etc.) but that's just me.
Just a point about how rules are followed. Do you follow the word of the law, or the intent? Since the jump start thing was such a debate last year in AMA I thought it was applicable. I like analogies. I get your point that since you can't judge helmet internals easily, you err on the side of caution. History is full of examples of simple rules to protect the most people.
Totally depends on the rule. Intent is usually factored in when we're deciding the penalty portion, with a jump it's a moot point. We use common sense in the enforcement to begin with so the penalty is always a stop and go. We always tell the grid marshals to err on the side of the rider in making a call like that. The whole moving in the box when putting it in gear thing would never have been called a jump.
I've taken an Arai to the guy at the AMA nationals in worse shape then that, he didn't say anything lol
