Harley's ABS was a first step into Stability Control, as as such it has limitations as in cornering and off-pavement use. Bosch is now showing off the enhanced functions of their latest ABS/MSC systems, which encompass much more, including Hill Hold Control, Anti-Rollover Control, & Anti-Wheelie Control. Here's a link to their YouTube video. No mention of whether you'll be able to select or deselect any function when they become standard.

 

Wow. Very interesting.
I'd be curious to see what a system like that would add to the price of the bike though.
ABS alone is an $800 option on some HD models...

 

Not to worry - I'm sure Harley will charge twice as much as other Manufacturers.
