I have had them on my R65LS for a number of years, through my cafe phase and now as a sidecar tug. I had mine powder coated satin black and polished the ribs on them. I just like the way they look more than the newer style. People call the older style peanuts or kidney beans. I think the new ones look like a box of tissues for blowing your nose. Just my opinion.
The only problem with them is people value them more than I think they are worth. New ones are expensive and used ones usually have a few broken fins or grind spots from dragging a head through a corner.
