Information on installing SSB on the new 2021 GSXS1000 is available.
It seems that it can be installed with a little processing of the side cowl.
Apparently, if you make it so as to avoid the cowl, it seems unlikely that you will get the effect and strength of the bumper, so I would like to use the SSB for the old model GSXS1000 as it is.
