I've done trackdays on my naked KTM 950SM, you can do it on the Multi, though I agree the 900SS isn't a good choice. You want the newest, best maintained, most reliable, safest bike you own on the track.
I don't find the top speed straights particularly fun, they end in corners that will require fierce braking the faster you go. Hitting your lines, getting better every time you see the same corner again, and enjoying the vibe and camaraderie of the track are the highlights. You can have just as much fun on a Ninja 250 as a full-on superbike.
Have fun and don't worry about anyone's lap times, including your own.
