You no longer need to tie the chin strap every time, and I feel it's a very convenient attachment. The metal fittings are made of metal, so they should have a certain amount of strength. I have been using this buckle since the day I bought my Shoei Z-8, and I have been using it comfortably for several months. Basically, it should be installable on helmets with a 25mm wide chin strap. For reference, I have listed the helmets that are likely to be compatible below. ・SHOEI z-8 / x-15 / z-7 / Glamster ・OGK Kabuto F-17 ・Others (25mm wide belt) ★Product Condition★ Brand new and unused. Please note that there may be initial scratches due to being made overseas.
