I went the other way after buying a 900 ie years ago, second hand. The bike came with 15T front and 41T rear.
Most riding in the country, Australian outback, long haul rides. Bike was very jumpy for me, wheelies in first if launching from lights etc.
Went back to standard, 15T front and 39T rear. In answer to your question, I had to remove one link from same size chain to adjust to fit.
If still considering new chain and rear, just order a couple of extra links, easy to remove with either proper tool, or a small grinder to take off the rivet heads and then punch out the pin.(s)
I did try once a 14T front, but found chain rubbing hard on swing arm slipper, (too close) but mine is older double sided arm, yours may be different.
The Rizoma thing is for using a paddock stand to lift rear of bike, not sure how that one is attached.
Just some ideas,
