My 550 came from the PO without the centre stand. The bike has an old 4 -1 pipe, so it's a but tricky to have one, I figured I'd never miss it... but then as I did more work to the bike. Chain, sprockets, brakes, tires, etc. it killed me to not have it. I hunted one down and I put it on & off as needed when I'm working on it. I don't use the spring, just the long hollow shaft. I couldn't imagine living without it. I especially like to have the bike on the stand when adjusting the chain. And on that topic, I have become meticulious about keeping the chain adjusted exactly to spec. There's already so much drive train noise and clunks, that a loose chain just make it all the worse.
