I spent years riding sportbikes and had this protective leather suit made in 2006. I designed it based on the Apollo 11 and Apollo 16 EVA suits and had it made by a well-known motorcycle suit tailor. I used it as memorable branding for my YouTube channel for years before quitting motovlogging. That bike is the Honda Vultus, which looks a whole lot like the Akira bike (but in black). Not my bike though.
