Tried the 1-up to 2-up raisal test you asked for. It raises somewhat at least, I have nothing to compare to but something happens.
I don't see any difference when changing EDS between COMFORT/STREET/SPORT though.
With 150 hp and a 170/60ZR17 tire on the back wheel, I'd be amazed if it's not made for wearing my kneeplates out. Scraping the center stand is however FAR from scraping my knee!
