Interesting comments on this, I may be the only Sikh here who wears a turban and can chime in...
My dad grew up riding bikes as well, we're from Kenya, there were no helmet laws and he rode with a turban. He's had 6-7 accidents, and all were without a helmet, he tells me luck was more on his side on walking away, he did break a bunch of bones. Today, we both ride, and don't get on a bike without a full face helmet, its a no brainier
As for the law, it should be for everyone, not a particular group imo. Just like some states in USA, and alot of countries around the world. Otherwise, I don't take it personally, and its their heads, brains, and life, they pay for the bike, and know the risk, politicians aren't in it for safety, just votes and money, never trust them to start with.

I like bikes because they make you forget about politics, work, problems, etc... and focus on the next 5-50 feet using all 5 senses, whether I'm christian, Buddhist, or Sikh has nothing to do with bikes, so I don't see why I should associate them with religion to start with.
As for the folks saying Sikhs can't rely on God, we don't have a God :lmao: We have Guru's, much like Buddhism the word Sikh literary means "Student, or to Learn" and thus devote life to learning, seeing the oneness in life, and how all beings are equal. The turban itself is a symbol of this practice, just as Gotema (the Buddha) tied he's hair in a knot above he's head to signify enlightenment. It's fairly simple, and very close to Rastafarianism, why they use lions and keep their hair too. Things like Ego, desire, and lust are no no's, like the Buddhist seven sins. Too me (personally), wanting to constantly show a turban while riding a bike (which is a costly hobby, you can sell and feed the poor, as a true Sikh, remove the desire for material I guess) is a status of Ego/pride, including holding onto a concept rather than practicing what it stands for.
Just my two cents, as bikers, that's what we are as one, it's what unites us and is a common factor, if one of us get's hurt, gear or no gear, I like to think we can help each other. Division from sport riders, cruisers, enduro's etc.. is enough as it is, religion, clothing, and saying so and so should pay more for being in their eye's more free, is further division. I can say a squid riding in flip flops and wearing a helmet, is no better.
