How does the ABS brakes work on the Chinese Scoots
« Thread Started on Jan 10, 2007, 10:11pm »

I have a Roketa Fiji 150 and it has what they call a ABS brake on the front disc.
Does anyone know how that works?
As I see it they have mounted some additional cylindrical like device on the caliper. But I can't figure out what it is it is supposed to do.
Thanks

Mine seems to work fine. I guess nobody is real sure how they work, but here's my guess. I think the abs units on chinese scoots are actually pressure regulators. They look much like pressure regulators used for other purposes. They certainly don't modulate braking pressure the way true ABS systems on cars do.

It's probably a pressure regulator of sorts. Like wat they put on the gas meter on your house. No matter how hard you squeeze the brake lever, the pressure maxes out at a pre-determined level. Or maybe it's more complicated than that. I'm sure that the big dawgs will give you a more apt description.

you've pretty much nailed it, that's all it is, a pressure regulator. Real ABS has a wheel-speed sensor, an electro-mechanical switching valve for releasing and reapplying the brakeline pressure rapidly, and enough wiring and computing power to make it all work. all that pressure regulator is gonna do is reduce your overall braking power so that you can't lock the brakes.

if it was me, I'd toss the thing and connect the brakeline directly, letting my fingers do the pressure regulating.

Thanks for the info. I sorta suspected it might be a simple pressure regulator, but I wasn't sure. Since there isn't any computer, and sensors, it is hard to see how they could do it any other way.

Yeah I think replacing it with a plug is a good way to go too.
But I give them the benefit of the doubt and give it a try for a while and see how it behave and works.

Hey robbovious, I like the way you say "Real ABS", because my scoot locks up if I brake hard. I have the X-rays of my left collar bone to prove it . Chinese ABS, what a joke!!!! LOL

the abs on chinese scoots is nothing more than a adjustable pressure regulator/fluid damper. it prevents someone from locking up the front wheel in a panic stop on DRY pavement. I'm sure the device has some usefullness with people not used to riding motorcycles. People that dont know any better than to grab a great big hand full of brake lever in an emergency

On a Chinese scooter I read a sticker that said "ABS = Able to Brake and Steer". Now that's High Tech.

I have long been a critic of the "ABS" claim. I have those brakes on my Matrix and they aren't so bad but it's a gimmick and they aren't true ABS. What a lot of Chinese bikes lack in engineering, they try to make up with gimmicks such as "ABS" and alarm/remote start systems. I find it refreshing that some of the Chinese models are dropping that stuff and trading it in for better engineering and quality. The best brakes I've ever felt on a scooter were Vespa. The second best I've felt are on the Pegasus. Go figure.

I weigh nearly 230#. I posted a couple a weeks ago that I nearly plowed into several deer on the road. The so called "ABS" (short for absent) brakes worked (sort of) I had to lock em up..and the front one didn't dump me and in fact my skid mark was intermitment as if it was a real ABS. In any case I didn't react the way I should have because I didn't pulse the brakes myself. Dennis is right about practicing panic stops. We should and we should often because pulsing the brakes may save your butt. In my case my fat butt.

I have the famous ABS on my Avanti 250. The first 250 I had didn't have enough time to show me what they could do, but since getting my new one, I have practiced a lot of panic stops in different situations and the ABS brakes don't feel like anything special. The bike stops and whether it's a pressure regulator or a true ABS system, it matters very little. I am just getting used to how they feel in every type of situation. Once I know what they actually do (rather than what they are supposed to do or how they do it,) I will feel a LOT more confident on my rides.

Before I go out and remove the "abs" can in my brake line, has anyone done this yet? Any drawbacks? Any change in performance? Thanks

If you had never heard about ABS on a motorscooter, trust me,you would not be worried about it. The only reliable scooter ABS system is learned from practice, practice, practice, until it becomes instinct.

My Lance is suppossedly ABS on the front. I do not know--am not that mechanical. It does stop well and I have never locked it up. But I definately agree--practice and more practice on braking in all kinds of situations is the best ABS there is. The Ohio motorcycle manual says it all: Ride Within Your Limits. There is no mechanical substitute for practice and skill development. I believe it and I practice it.

There may come a time when you wish you could damn near lock the front wheel up, and don't want some dumb restrictor valve in the way. I don't know any substitute for experience. You ride until your machine becomes like a part of your body, and that just takes some time. I can recall several times when my front tire was squalling like a turpentined cat, and the bike still held on to the line. The problem gets out of control when someone panics, and cuts their brain out of the loop. You just have to tough your way past that level. The best time to have a panic attack is after the battle is over.

I've got dual discs on my scoot, whether they're really "ABS" or not I couldn't say. But they're a damn site better than the brakes on my '58 Sportster, which were purely for decoration ... as I learned from experience.

A buddy of mine has a Genuine Blur, and his front brake will throw you over the bar. I think my craptastic ABS braking system helps with one very important aspect: NEWBIE RIDERS. I can factually tell you that I've locked that sucker up, and felt it grind to a halt (right quick) and realized that I hadn't sent myself airborne. It may be less than optimal, but for the first few months, it was probably best for me to have it. I think it's a necessary evil. Think of the average chinarider.... "I bought my new toy bike on ebay, and now that I've got my mirrors duct taped to the bars after I broke the bolts off I'll go for a full throttle ride! Who cares what time of night it is, now hold my beer!!"

Let's be realistic, folks, those people aren't showing up in here. They actually think dog is spelled dawg, and don't understand why we're not posting our pictures of post opertative animals who have had limbs removed.
