Some folks ( like my pal Jimbo ) ride in a style to not need ABS. For him and folks like him ABS is just added weight cost and complexity. My Dual sport rarely sees pavement. ABS would be a waste there too. Non switchable ABS ( if there's no way to piggy back a switch in ) is a deal breaker for some folks because changing direction by sliding the rear is real thing. Sometimes it's a turning technique and once in a blue moon, it's a crash avoidance maneuver. I reckon folks who escaped death or grievous injury by sliding the rear are probably the most insistent about at least being able to switch it off.
