This is a 47L model that can store two helmets. I am selling it because I am changing vehicles. I haven't ridden with it installed much, so it's in clean condition with no noticeable scratches or stains. Please refer to the manufacturer's website for product details. https://www.daytona.co.jp/products/detail/76885/ The included universal base is unused and will be included as is. This is a used item stored at home, so I would like to do business with someone who understands this. Please note that when shipping, it will be simply packaged (wrapped in air cells). No returns or exchanges are accepted.
