I purchased a motorcycle in November 2024 and bought several helmets. This item has only been tried on and is unused. I will sell it at a bargain price to someone who will love it. Reference Purchase Price Helmet: ¥13,467 Intercom: Unknown Total: ¥13,467 Product Name: Marushin Sports Jet Helmet TE-1 Size: L Color: Flat Gun Metallic Equipped with an inner sun visor Includes the original helmet bag. The installed intercom is included as a service. However, there are no manuals or spare mounting parts. Thank you for looking.
