This is the nissin brake pin hanger design and all of them are the same (honda, yamaha, suzuki, etc.).
You can buy quick removal brake pins - used for isde setup if you anticipate needing to change brake pads during the event. e.g. you have a short work period each day to change tires & perform other maintenance, etc.
This give you a 8mm hex head vs an allen to remove the brake hanger pin. The disadvantage of this setup is that the 8mm hex protrudes out of the threaded area and can be damaged by impact with rock, etc. Which is why I bought a set long ago and never installed them.
