Common sense is also to create a legal situation where if the turban can't come off, create an exemption for it to stay on provided they pay a different insurance agreement that covers the what if it all goes wrong without a helmet (which is what I think the case is now).
So the reality of a Sikh male riding a motorbike is quite rare, not because they are prohibited to by the law, but because it's relatively impractical to pay for insurance based on not being able to take sensible safety precautions. Generally this is an acceptable compromise for religious groups because if it is really necessary then it can be done.
