I Installed the RIVCO centerstand yesterday and here are my impressions;
Install is pretty easy, it's a very high quality part.
If you don't have saddlebag guards you are probably better off not installing it, (you would have nowhere to grab to get it up on the stand). This is also made more difficult if you have the saddlebag guard bags installed as this prevents you from getting a good grip on the rail. You could get it up on the stand without the guards, but it would be tough.
If you have the progressive 440 shocks that are 12.5 inches long then this stand would probably be about perfect. With the stock 12 inchers it's a little tough to get up on the stand. The first time I tried to get it on the stand, I thought; no way, but after a bit of practice I could do it. I found that by rolling the back tire up on a 1 x 6 that it was pretty easy to put it on the stand. With the 1 x 6 under the rear tire there was still about 3/4" of clearance between the board and the tire, when the bike was on the stand. For this reason I think it would be about perfect for those with 12.5 inch rear shocks. Also my back tire is due for a replacement at 5500 miles, (it's down to 2/32nds), so I'm sure that this contributed to the difficulty.
I have found that if I get the bike rolling backwards and use the momentum to pop it on the stand it is much easier. I can get it on the centerstand using this method without placing a board under the rear tire if the surface is not slick, (so that the stand legs can get traction).
The bike is VERY stable on the stand and I can easily rock it off of the stand while seated on the bike. I haven't tried it yet but I'm sure that it would be easy two up.
The stand looks like it belongs on the bike and is out of the way when retracted. It's still easy to back the bike up as it is far enough back not to hit you in the calf.
It is GREAT for working on the bike as you no longer have to pull out the jack to raise it level. Makes cleaning the crud off the back rim easy and I'm sure that oil changes will be easier........mobe
