I can't speak for the Tracer, but on my 2015 MT-09 one side has a conventional clevis pin with cotter pin but the other side is 'permanent', i.e. riveted or similar. Probably needs an angle grinder or something to get it off. Maybe it saved a couple of Yen in the factory, or perhaps it's so the complete assembly has to be replaced after an off, thus generating more spares revenue - who knows?
bobh is correct. I have replaced my standard pegs also - firstly with FJR pegs but when the rubber pad started wearing I fitted a set of specially made Pivot Pegz which work a treat and are really comfortable.
