Greg, greetings!
As far as I know, none of the 955i series came with main stands - what you need to get is a rear wheel racing jack with a round piece that slots into the stand holder hole in the center of the rear axle and then you lever the jack down, just like you would with a main stand on the bike, but the jack has a long handle that makes the jacking procedure very quick and easy. Unjacking if you're on your own can be a bit of a fiddle the first few times, but the main thing is to REMEMBER TO MAKE SURE THE SIDE STAND IS DOWN before unjacking the bike on your own. Sounds elementary but it's a new check to learn and make intuitive if you're going to use the racing jack much.
Other than that, the only other 955i things I can say (and I have a Speed Triple, a Sprint, a Tiger and a Daytona, all 99-01 955is) is don't try to pull the bike down going into corners like regular bikes - just think it and lean a very little, practically, and it will go there by itself on rails, especially the higher CG bikes (i.e. all with regular handlebars - the Daytona is somewhat of an exception, but not much of one).
Then don't forget that the triples have a wicked acceleration curve, and torque pulls strong from around 1,800rpm all the way through 7,000rpm. This is due to the triple design having the lower rpm grunt of a twin and also the higher end torque of a 4 or 6.
What this translates to is this: take it easy on the gas coming out of curves. Usually one would go into a curve and then lean against the main shaft and camshaft torques of a 4 or 6 cylinder transverse motor because the gyroscopic action wants to make the bike stand up straight when you get on the gas of those bikes. You lean off the side to hold the bike down in its curve while applying the gas to keep it tracking through the apex and exit properly, while adding gas to compensate for your lean.
Do that on a 955i and your rear will want to step out on you in a split second. This will be at least a fishtail, but if you have grippy new tires, it could be be a catch-and-highside just as easily.
So if you want to get into that kind of thing, make sure you ease into it well after you know how your bike is going to behave.
The Sprint is a mild mannered beast compared to the Daytona and ST3 for sure, but it will bite you if you're used to other kinds of bikes.
As with all well-intentioned advice on the internet, please, YMMV, JM2c and HTH. I've been riding since 1975 without grave injury, started on a 500cc Speed Triple and have ridden many different kinds of bikes, including those one had to lean off of to hold down coming fast out of corners... ' )
