Yamaha Motorcycle Helmet Jet YJ-20 ZENITH Purchased new online, I tried it on but the size didn't fit, so I'm listing it for sale. I've stored it for about 3 years after purchase. Size: L (Head circumference 58cm~59cm) There is no receipt or proof of purchase. Due to a visual inspection by a non-professional, I haven't been able to check the fine details or parts that require disassembly. Although it was only used for a fitting, please refrain from purchasing if you are looking for a perfect item, as it has been in someone's possession once. Thank you. Size: L size
