I was taught in the MSF course you don't emergency brake while in a turn, you straighten up then stop, course this seemed odd to me cause not all roads are straight.  and when it's an emergency, it can happen in the middle of a turn. and running out of road seemed an issue too.  

abs prices need to come down before this becomes mandated. but I guess it wouldn't stop you from buying used bikes without abs

I don't like anything to be mandated, rewards for good behavior are cool though  

being experienced riders like most of us here ,we should never have an emergency stop, you should be riding safely and antisipate these things from happening.
That is why police and highway patrol never call accidents accidents,they call them what they are, "Crashes".
But as we all know idiots are out there all the time,some times we can spot them by there actions ,and back off to let them crash without  us. 95% percent of crashes are caused by one thing,following to close. speed being another bigee.
I can only drive a car now ,but you can bet your sweet A$$es ,I am your best friend out there, I always give M/Cs if I am lucky enough to pass one plenty of room. and I take extra care at intersections, you will never be hit by a red Miata with a limey in it.
As for abs brakes ,never got the chance to try them,but from what I have read they work very well ,I have not heard a bad report,but then I only read about BMW ,a bike I still call the Rolls Royce of M/Cs.

Dasch, I don't know just how BMW does it, but back when Honda had the linked braking system on their sportbike they did it by activating different sets of pistons in the calipers. The rear had two piston sets, one of which was activated by brake torque reaction from the front brake. The front brake had three sets, probably on each of two discs. Rear brake application directly activated one set of pistons on the front and one on the rear. The front brake reaction activated the second set of rear pistons, so there was one piston set front and two rear working. Front brake application directly activated two sets of pistons (of the three) on the front, and the brake reaction activated one in the rear. There were, of course, proportioning valves. The net result was that activation of either control braked both wheels, but the braking was "stronger" on one wheel than the other. Either control could lock its wheel, but I don't know whether either control could lock both wheels. Magazine reports of the time said it worked very well indeed, but there was the usual carping about not being able to use only one brake. But then I used to hear gripes from truckers about front wheel brakes, too, along with the stories about how they would misadjust the brakes so the steer wheels didn't brake. And there were trucks made with a control for slippery roads which reduced front wheel braking.

Charon, I really don't know either how BMW did it, that might be the same principle, or they simply let the hydraulic pump and ABS computer handle force distribution. Whatever it is, boy... it works. It looked something like this:

A naked bike, weird to the bone, with all the crazy monolevers, paralevers or whatever they call them. Amazing.

Dasch, a while back Fred Rau, in a back-page article for Motorcycle Consumer News, wrote of having mixed feelings about the BMW with the integrated ABS brakes. He said it dropped him once, and saved his bacon once. He said he was driving the bike onto a ferry, which had the obligatory slippery steel deck. At very low speed, he touched the brake (I don't remember which brake); the brakes locked (possibly because of the power booster on the brakes), and the bike went down. In the other case he was running on a freeway in LA somewhere. He looked aside to admire a BMW sports car, and when he looked back the car ahead of him had dramatically slowed. He got on the brakes, said he heard one "chirp" as the ABS took over, then stopped straight, true, and quickly. He credited the ABS for avoiding a crash.

Other articles on ABS say implementing it on a bike is difficult. On cars, it is said the ABS is allowed to quit working as speed drops to about five mph. That is because it becomes more difficult to sense differences in wheel speed at low speeds; cars don't fall down; and those low speeds don't usually cause much damage. Motorcycle systems have to sense speed right down to a stop, because motorcycles DO fall down. My guess is the ABS works well enough from speeds much faster than a walk down through stop, because it already has data to work with. But at very low speeds, such as paddling around a parking lot, the initial lockup which would cause the ABS to start working is itself enough to drop the bike.

I have a chinese scooter that I'm doing some work on for a customer.It has an ABS front disk brake. Not sure if it works, it's just installed where the hose attaches to the caliper.

Can't cost much, these scooters are cheeeaaap!
