I guess i'll be the one "crashing" the party here. I bought mine explicitely without ABS. I spend most of my time on dirt roads, and I have seen proof of how well ABS works in these circumstances. Turning it off is a great option, but if you shut the bike off -with the key- and re-start it, it'll be back on, and will have to be re-deactivated. <-- not a real word.
A guy like me after the adrenaline rush of doing a hillclimb, stopping up top to take a break for a few minutes, would then start the bike and proceed downhill with the ABS on and risk a nasty crash.
I just wish the rider could have the option of toggling it on or off manually and leave it as is until he/she decides otherwise.
I do agree however that not a lot of people can outperform ABS on tarmac in almost all conditions.
The Highlander's ABS saved my butt just a few weeks ago.
