Typically, the inclusion of a helmet with the purchase of a motorcycle, such as Royal Enfield, varies depending on the dealership and the specific promotions they are running at a given time. Some dealerships may offer a complimentary helmet as a promotional gift, while others may include the cost of the helmet in the overall price of the motorcycle.
Regarding the color and size options for the helmet, it again depends on the dealership's policies and the specific promotion. In some cases, you may have the option to choose a different color or size for the helmet, but this may also be subject to availability and any terms and conditions set by the dealership.
To get accurate and up-to-date information about the current promotions and offerings, it's best to contact your local Royal Enfield dealership directly. They will be able to provide you with the most accurate information regarding the helmet and any customization options that may be available.
