a very important question b4 purchasing clipons. I think that because of the shape of the triangle on the 2018 sv650abs, it might be impossible to use a riser with the clipons. I think I'll be obligated to use a type which is on the same level as the clipons ring otherwise it might not fit.
any specific recommendable type or brand?
I don't about the 3rd gen specifically, but there often is. If you don't restrict range of motion the switch pods on the bars will hit the tank.
I usually glue or JB Weld small squares of aluminum stock to the steering lock tab on the frame.
