Reminds me of the scream on the intercom when
she scraped her boot on the handling parkour during named safety training (they split that into several sections, the final stage is like "free riding"); well, that's what their getting for sitting like a frog... tuck those toes in

Despite the firmer Wilbers suspension you start scraping parts rather quick on the racetrack-tarmac they have there, OK in that controlled environment, I won't do such on purpose on normal roads...
Before the Wilbers (and the actual reason I welled the $$ out for that upgrade) I had a nasty incident while riding 2 up by hitting a some hump in a RH corner, undercarriage (mainstand & pegs) hitting the deck, forcing the ST vertical and running wide...

I did not cross the line (barely), but imagine someone coming the other direction would have cut that corner...

By the numbers given in the title the payload of an ST1100 are only 200kg/440lbs... 2 up with luggage you're well beyond that...
Had the stuff designed for more realistic 250kg/550lbs max and found it the best investment ever...
(and whenever I switch to my '94 with its OEM suspension it feels like riding a sofa...

)
