Well after my "little low side" I ordered a new set of frame sliders, tails sliders, and bar end sliders.
After I installed them I was moving the bike around and was reaching for my rear stand ..... arghhhh I lost my grip on the clip on and to my horror (an in slow motion) the bike fell over on its side

.... but wait, its not laying on the ground ... it's floating ... no but it was resting peacefully on the sliders a couple of inches off the deck, not a scratch ... now that I like!
So the answer to your question is a resounding .. yes they do help and they look the business as well.
