Personal opinion: If it were no extra charge or a minimal extra charge I would probably have gone for ABS. But not for $1,000.00. Sure there are some great safety benefits from ABS in a panic situation, especially for an inexperienced rider. One possible down side is you may get used to it on one bike and then not have it on another bike and get in trouble.
I personally like to take a bike to a large empty parking lot and place some markers on the pavement. Then ride towards them at speed and practice maximum braking techniques in order to get to know your bike in that panic situation. How short can you stop at XX mph with front brake only, rear only, combination, 75% front/25% rear, etc. The Valkyrie will be much different than a sport bike that can do 100% maximum braking with the front brakes only. This bike can stop very good for a big cruiser but it takes practice. The time to practice is when you decide, not when the driver of that car decides.
Of course, that's all relative to the pavement conditions which change. In the rain is where ABS really shines.
