I dont know what to do for my dad. He has an 09 KTM 450 exc. The factory turn signals are pop on and they dont seem to go back on well. They also fall off with hard bumps. I have the 530 exc and dont seem to have that problem with mine. I told him to stop flying off cliffs and the signals would stay on but he doesnt listen. so are there any trick turnsignals that are a must have?
