I purchased this helmet for 22,000 yen at a Yamaha store. I intended to use it, but I bought it without considering the size. It was too large to fit in the under-seat storage of my scooter (Yamaha Vino), and the seat wouldn't close. I ended up buying a jet helmet, so I'm selling this one. I haven't tried it on other bikes, but it might be a tight fit for scooter under-seat storage. I've only worn it twice. There's a tiny scratch on the right side, likely from putting it in the under-seat storage, but otherwise, it's in good condition. Please refrain from purchasing if you are overly concerned about minor imperfections. Size: L I threw away the box because I intended to use the helmet. I will ship it in the included carrying bag and another cardboard box. 【Brand Reliability】 Roll Bahn is known for providing high-quality helmets.
