Dunno. Rode it, as I said, low speeds, parking lots, rush hour, relatively high speeds... didn't feel anything strange. Wanna stop - it stops. There's no booster or any enhancement that I felt. Squeeze ligthly - it slows down lightly. Squeeze harder - it simply stops. It acts like any other good bike I rode, difference being in that you actually feel both wheels brake whatever you engage. Kinda hard to explain...
Bill, I agree on the cost 100%. It is probably very expensive now. But give it a few years. Look at cars. Even smallest Kias and Hyundais have it now, and they are still cheap cars.
But why do you think there will be more accidents??   99% of people should not ever sense ABS activating. Rookies may, and it will probably save their butt then - it's a win-win, right?

On the same token - we just got a brand new Ford explorer (exploder) on the job. One of the pamflets that came with it reads  - if you need to slow down rapidly, depress the brake pedal as hard as possible and concentrate on steering. It actually instructs you to rely solely on ABS. That might be a partial problem. Taking control out of your hands (feet).
