If you just need to get the front wheel up for front end maintenance, put the bike on the center stand and the use a small bottle jack with a short piece of 1x4 or 2x4 up against the engine sump. If you have a friend handy, you can use a pair of jack stands instead of the pump. Put the bike on the center stand, have your friend slowly push down on the rear of the seat while you placethestands under the frame tube on each side. Be sure to pad the standsso they don't scratch the frame paint. If you need to do more serious work, and you have open ceiling joists, you can remove the fuel tank and loop a strong nylon ratchet strap around the top frame tube and the joist, and ratchet away.
If you would rather stick with padlock stands, Pit Bull makes some of the best. The one in your link will probably do the job of it will clear your pipes, but those are usually pretty unstable.

I have been using a jack real close to the Black Widow jack for the past 30 years or so. Never dropped a bike off of it while I had it under anyone of my bikes. I use pieces of 2X4's instead of those moveable adapters that comes with the jack, It makes the bike a lot more stable using the pieces of 2X4's. I stack the 2X4's to make sure my header is not touching the jack.
Here is the jack and the pieces of 2X4's holding up my GSXR pictured below.

You can see in some of my clips I struggle a little getting it on the stand. With the 130 tire it's easier but with the 120 I have to pick up the bike's ass end to get it on. (I don't have a grab bar anymore) You have a 16" rim so it has to go up higher than mine. I suggest a 2X6 block of wood under the front tire. You can easily remove it once the bike is on the stand.
BTW, nice bike.
