It's normal for a chain running like that with a wheel off the ground, under no load.
Nothing to worry about, absolutely normal - our FZS 600 does that with a nicely lubed, properly adjusted chain, when the bike is on it's centre stand - nothing to worry about.
Our FZS 1000 and FJ 1200 do exactly the same, and our Aprilia RSV 1000 is much worse - but all their chains are good and all work perfectly, in normal riding.
