Unlikely. A Sikh's headdress is their uncut hair wrapped in cloth, so the size and structure of that is very variable. It's not feasible to make a helmet that fits over that without leaving a lot of space, and space makes helmets ineffective.
Inflatable liner might do the trick. They would look like Gazoo though.
Elon Musk can design an inflatable submarine like headdress enclosure that will be 2X better than any helmet and half the weight. Plus it collapses down to a Walnut sized headband ornament when the rider is not in motion. The submarine's inflation mechanism is powered by the airflow proportional to the motorcycle speed.
