The sf brace won’t fit on the new grom. Gcraft makes one for the new grom thoughIf you’re going to be messing about with the shift lever, I can recommend the Chimera shift shaft support: Chimera Billet Aluminum Shift Shaft Support- Honda Grom Monkey 125 2014-2020 and the IMS shift lever: IMS Honda Grom Shift Lever as I have them on my Grom.
With that shift lever, I believe you can tap a bolt into the folding nub, and extend it without rendering your shift shaft vulnerable to accidental damage from drops and crashes. If you have a buddy who welds, welding an extension onto that folding bit would be even better (and less fiddly).
I did the koso rose joint too and the gcraft shaft brace with oem lever and I’m happy with the feel.https://www.takegawauk.co.uk/product-page/zeta-msx-gear-lever
In the end I settled for improving the action with a ball jointed link replacing the bent bar and i am very happy with that for my minor arthritic ankle and foot condition.

Sorry these are UK links but I'm sure you can find equivalents in the US.
