Knifemaker,I have to say, as always, dude You are right!!, I checked for cracks(LOL), and found another one on the other peg. Holy Sh...t!!! So I called the previous owner as he´s a close friend, and he spoke the truth. He has fallen on everybike he has ever owned at least twice, that bastard!!!.
So I´m actually using the rear pasenger pegs that fit even better and feel better when using the shifter. Now I´m looking forward to buy a couple of used rear footpegs to put on my bike.
