I have been looking at some clip ons and it seems inly 2 brands vortex and woodcraft make them with the clamps that are lower on the stem, like below the wire clip that needs to be removed while taking off the OEM bars. All other 'universal' 37mm clamps are as tall as the stem right up to the top bolt or even over a hair. My question is can these still be used? And if so should I leave that round thin wire in place or pop it off. Does it have any other purpose other than not letting the OEM bars slide right up and off? I've researched it a bit and have seen posts in the 500r forums with pictures , and the clamps are even with the top of the suspension(riser?) bolt and he says he has no problems.
