The cost of shipping a Royal Enfield 350 from Hyderabad to Bengaluru through railway would depend on several factors, such as the weight and dimensions of the parcel, the distance it needs to travel, the specific railway service provider, and any additional services or insurance you may require.
To get accurate pricing information, I recommend contacting the railway authorities or shipping companies that offer parcel services in India. They will be able to provide you with the most current rates and any specific requirements for shipping a motorcycle.
