If you go by the RTO rule and regulations it is mandatory.
all the motor cycle should be fitted with Saree Guard and number.
Besides, I have seen sometimes how a saree guard can be useful, including a skid launching an avenger with no saree guard very near to me, because the lady’s dupatta caught hold of the tyre. So if you plan to get any lady in kurta/saree, think twice before removing it.
