These are the ones I put on my Commando and they improved the front end a lot compared to the springs that were in it when I bought the bike. Not sure if those were original or not. This is my first Commando so I don't have much to compare to though. I suspect these may be Emgo brand from Taiwan and they seem to make reasonable quality stuff.
I fitted cheap RGM "progressives". They seem to work really well....makes a big difference over poor surfaces at all speeds. There don't seem to be any downsides. RGM could be using the same source. They came with no packaging, just wrapped in paper.
