I took my dad's 1100 (not S) for a rip to the black hills, south dakota a few weekends ago, and completely changed my view on it. It is a mean machine, kept up to the jap sport bikes no problem (could be I enjoy driving at 99% of my ability and they're scared to) but it just TORE IT UP!
If you've ever been there, the roads are insanely fun, fast, and twisty. some are slow 15mph sharp corners, quick elevation changes, others are up'n down all around fast but gentle 80-90mph curves. It just so happened that when I hopped on the bike for the first day it was a little soft, so I cranked up the preload about 7 clicks (just the rear) and it just seemed to be dialed in PERFECTLY. The bike and I were a match made in heaven. It felt so effortless to beat on it in the curves and twisties that I sometimes forgot I was driving, and was just enjoying being shuttled down the road.
I can't relate it to an ST3 from a "beat on it" hands on experience view, I've only puttered around on an ST3, down the highway, not riding it hard in the corners...but the multi...man oh man it's a serious machine. The ST3 left me with a "...it's a bike" feel. I'd almost consider giving up my monster for it....ALMOST! well....I just might.
OH! and it wheelies all over the place if you're into that! lol
If you couldn't tell, I was completely BLOWN away by the performance and comfort of the Multistrada.
and just for fun...only about 20mph in the pic so that's why I'm not over further!
