I saw a post from this site from somebody who ordered the Versys 650 lowering blocks for the Z650. I have just done the same and can confirm they fit perfectly

It's a 2020. So these blocks will definitely fit the 2021 model. Moto Werk are also very professional and whilst the blocks are not cheap (to buy in Oz), they are worth it. Comfort is significantly improved and still never scrape the pegs, cause they are so high. (maybe I'm not aggressive enough)!

Thanks for the info! I believe you, because the 2020 Versys 650, 2020 Ninja 650 and 2020 Z60 all have the same part numbers for front pegs (34028C left and D right), but I was told the same as @gcorgnet from Moto Werks. I can't imagine what would keep the lowering kit from working on my 2020 Ninja 650.
I just ordered the peg lowering kit for the 2020 Versys 650.

they should be just fine. I asked the same thing for my 18 Z and they said no. I think it's because the Z is somewhat of a sport bike, and they don't want to be responsible for scraping of pegs.
I installed them and have never had scraping issues. I don't corner like mad, but have had some fun in an empty giant lot and cornered reasonably hard and had no issues.
They are rated for less weight than stock though. One peg cannot handle all of my weight I recall, so keep that in mind. (I weigh 243lbs/110kg)
