Thanks for your response regarding the top box. Ahh, so it screws on. That makes sense. I was thinking it would get stuck on with some really strong double sided tape. I've decided not to go with the mirrors that I posted earlier. I don't think round mirrors will suit the X-max. In my searching I have found these https://www.revzilla.com/parts/2017-yamaha-tmax-530-xp530?view_all=&page=1&limit=96&facets=6387&price=&price_min=1&price_max=875&is_new=false&is_sale=false&is_made_in_usa=false&has_video=false&is_holiday=false&is_blemished=false&sort=featured I know that I've used the search filter for the T-max (x-max did not show in their filter) but I imagine that mirrors that will fit the T-max will also fit the X-max. I will message them beforehand to be 100% sure.
