So I want to remove my exhaust to clean the rear caliper and I guess it came with an allen bolt? (bottom one on the pic) Every video I see of someone removing a cbr 250r exhaust shows it with an hex bolt and yet for SOME REASON mine came with this abomination. Soo... Is this normal? And if so does anyone know the size of it so I can buy an adaptor. Thanks lol

Yeah i've cooled off now lol. Thanks! 🙏🙏
I might buy a screw extraction kit. Problem is its sideways, so im worried tapping hard on it might damage something.
Ill probably end up going to the professional to get it out lol

Man, sorry to hear about that bolt. That's a surgery you don't want to make a mistake with. Good luck, drill straight, and use plenty of penetrating oil (wd-40 or other).
