This is a helmet holder for the DAYTONA CB650R and CB650R. It's the type that is fixed by sandwiching it between the tandem step and the body of the motorcycle. https://www.daytona.co.jp/products/detail/92642/ Please be sure to check the compatibility information on the official page before purchasing. - Brand: DAYTONA - Model Number: 92642 I bought this intending to install it on a used CB650R, but the one I purchased already had one installed, so I am selling this one. It is new, but the storage condition of the box is not good. Please refrain from purchasing if you are sensitive to this.
