It's a great question. Aside from riding the S1000RR at CSS, I've never had a track bike with ABS. I'm probably not at the level that it truly matters yet, but the ABS system makes the lever feel more spongey. Removing it gives better control, feel, and feedback or so I'm told. Again, it's what I'm use to, so I figure what the hell?!? I'll leave the EBC and TC intact of course.
