Hi all, I am thinking about getting a rox ajustable riser for my 06 gsx 550. I would like to get the 2.3"- 4" SS Height Adjustable Risers, my question is that can I use my stock handlebar or do I have to go to a strait handlebar? And if I go to the strait handlebar can i reinstall my old heated grips or do I have to get new ones? And I'm assuming I will have to get cable extensions? I'm new to all this so any advice is appreciated...Thanks!!
