I had this Sato one before SSB crash bar.
SATO RACING Frame Sliders - Yamaha VMAX 1700 2009-2019 [Y-VMAX09FS-BK] | eBay
Luckily I haven't used it but I saw some bike crash video on Youtube, I see same kind(not Sato) bar snaps in hard crash.(well its end of bike anyway kind crash).
I believe, the Sato one will take care air intake from scratch when just tip over, but I have no confident something more than that.
Sato's construction is good, no mod required, just small spacer under airintake.
I got this SSB one because I really don't want get my leg pinched under this heavy bike.....
I did not know this GSG bar, but looking one on Amazon, its not cheap like Sato($220), I would not regret SSB($800) for heavy duty protection.

I'm sold when I saw SSB site with VMAX on ground with bar
