Why is there still so many bikes without at least the option?

Disapointing it is not on the Street Triple or the the 675 Brutale (two bikes I am thinking about for the spring, now that I am used to the bandit....!)

Because we don't need to be nannied, and most of the systems have been crap, cutting in too soon and giving odd lever feel.

However the BMW S1000RR, and Honda CBR600RR/Fireblade systems are meant to be pretty decent.

Still won't stop you crashing if you grab a handful of brake mid corner.

Do people seriously believe grabbing the brake mid corner with ABS will save them? God there isnt much hope for them is there! Smile

My understanding is that all the combined ABS systems on the Hondas work well, not just the Blade and 600RR.

In particular, what is wrong with Ducati's systems?

Not heard anything about that system yet.

The CBF600 system was crap, but the brakes were generally crap on that bike IMO. May have just ridden a dodgey one though.

I should add that my motivation for wanting ABS is for a few reasons:

1. It takes pros quite a bit of practice in the wet to stop as fast without ABS as with ABS. I am obviously a long way from that standard. Furthermore it has also been shown that most riders rarely use the full power of their brakes, even in the dry, for fear of locking the wheels up.

2. How can I gurantee that I won't panic brake in the wet if I car pulls out in front of me? I can't.

3. By giving greater confidence and safety in the wet, I can enjoy wet weather riding more.

Seperately, does anyone have any tips how to practice hard (emergency) braking in a safe way, on, say, a closed road, so you know exactly how much you have, etc?

+1 to what Big Ham said.

My firm belief is that as much as you learn good throttle control and learn to accelerate quickly, you must also learn the same action on the brakes. Slamming a throttle wide open doesn't work, it's progressive and involves loading the suspension and Tyre before really opening it up, the same goes for braking, how quickly and effectively you can train yourself to do that without panic is a massively important skill.

I think ABS is ok but as Ham says, it's not going to help when leaned over at a reasonable angle.

I also don't think learners jumping on ABS bikes and ignoring learning good braking skills is a great idea either. Bikes aren't cars and have totally different dynamics, adding sensors that just detect wheel lock/slip/speed aren't good enough. Until you have full fly-by-wire throttle/brakes and sensors on headstock rotation/lean angle sensors and suspension/swingarm movement - and a ton of data you can't really effectively have a fully effective system, and then you still have the bigger issue - a rider chopping the throttle during a small slide or applying rear and front brakes at varying pressures.

At the end of the day TCS and ABS have been going on cars since the 80s, they've only really started going onto bikes. I reckon in 10-15 years they'll be quite good but at the moment, they'll only save you from certain reasonably simple scenarios.

Add in more complex scenarios that have less margin for error and the failsafe systems fail. As Ham has said leaning over and apply brakes heavily can cause a slide. On a car this wouldn't be acceptable, on a bike it is.

Selling a bike marked with ABS without really knowing what that specific ABS system can be worse than having no ABS because you can be giving people a false sense of security.

In the wet it's all about being progressive. Even more so than in the dry. Most modern tyres should have enough grip to lift the rear wheel provided they're used properly.

A couple of ways to practice braking is going to a carpark in the wet and doing a few hard stops to get a feel for it.

Also look at doing a bit of off road riding so when you do have a front end slide, you won't crap yourself.

Fair Point Chris.

The 98 R1 doesn't have it, and no bike, anywhere, ever in the history of bikes has ever gone faster and Chuck Norris rides that bike. Case closed.

To absolutely confirm that, Brussels is about to mandate it on all new powered-two-wheelers, right down to 50cc peds, from around 2016 or 2017. If you think the current systems are bad, wait until you see the 50p worth of engineering that's going to appear on Chinese-take-aways. Shocked

That's a good point, make me an ABS system, you can spend 50p! Hmm.... Wonder whether this will lead to a DFT review of ABS systems on motorcycles and do a rating system like SHARP for Helmets on ABS systems, another nice way to spend tax money on a problem that didn't really exist...

That's a lack of education. The actual reason you shouldn't use full power in the dry is that you'll likely flip on to your head.

The same lack of education may well see riders thinking that they can brake full power in corners as you can with cars.

My bike has TC and ABS. Having these as standard was one of the main reasons why I bought. The ABS is superb and has been exercised fully on several occasions. The TC has cut in a few times when the rear has started to spin/slide.

Of course I would recommend these safety features to any rider but I too often hear the idiotic response of, 'Safety devices are for pussies' from many bikers. These guys would probably ride without helmets, if allowed?

I suppose it's natural selection in action?!

Why would this be a bad thing?

If you brake to the maximum of your brakes, what happens if something unexpected happens that means you have to brake harder?

I probably only use 10% of my potential braking capacity when riding normally, if I use them at all. Maybe up to 70% if I'm hooning. I know full well I'm not braking to the max so if I go into a corner far too hot, I've got a little something left over.

ABS will encourage people to brake to the max all the time. Car drivers have the ABS kick-in once in a blue moon but bikers tend to use it as a performance aid and it kicks in on every corner. If you're already braking at 100% and the corner turns out to be sharper than you thought, what do you do next?

safety features


I look at it like this.

Safety features are all very well when dealing with mass transportation for the masses. People who aren't interested in their vehicles, how they work or improving their abilities can benefit from systems that help them pay even less attention to what they're doing. This is why most people trundle around in front wheel drive shopping cars, stamping on the brakes, completely ignoring the concept of 'grip' or 'feel', happy in the knowledge that the safety features will probably save their arse from their own ignorance. The majority probably don't even understand what ABS is, how it works or what the limitations are.

But if you're an enthusiast, you want the purity of controlling your vehicle directly. You want to learn about it, improve your ability to do it, you treat the whole thing as a skill to be learned, improved and honed. You don't want to rely on safety features, you want to rely on your abilities - that's what is satisfying about the whole thing.

The ideal world would have safety features with an off switch. Sure there are times when it might be nice to have them, just like there are times you'd rather be in a Ford Focus than in a TVR, but they should be always be OPTIONAL.

So what you're saying is that you routinely ride beyond the scope of your skill levels and abilities? Because ABS and TC only kick in once you've exceeded the grip of your tyres.

A good rider would have a bike fitted with traction control and ABS and it would never be activated. If you're giving it 100% on the road, you're going to land up dead, you've got to have a safety margin for the unexpected.

I would question if someone who routinely pushes their bike beyond the level of grip their tyres afford them and has only been saved from a crash by a computer should be riding it on the road.

Also, who's riding the bike. You or the computer? In your case, sounds like it's the computer.

Anyway. For someone so obsessed with safety, you sure as hell chose a strange hobby. Why don't you buy a car? Makes much more sense. They have four wheels so they can't fall over, about ten times the tyre surface area and have all sorts of safety features like airbags and roll cages.

Totally agree, optional safety features are fine. There is a reason why all the GP/WSBK riding gods spend mountains of time on crossers and supermotos in the offseason/when training so being used to one or both wheels void of traction is second nature. They're at the peak of the art. The art being vehicle control (if that's what you want from biking). For me to get what I want I need the features off.

I suppose it's like rock climbing, you can do it with or without a rope. Some people get more satisfaction from doing it without the rope. This is one of those things though, it's based on opinion rather than fact, some people prefer the electronic safeguards, others don't.

I generally dis-engage all the electronics in my car (3 Litre Petrol BMW) - ABS, TCS, Stability Control - and more so in bad weather, not being able to pull out (Jolty start/stop) on a roundabout because of a small amount of wheel spin is not safe IMO, and with small slides good throttle management keeps things happy.

I hardly push my bike beyond its or my limits but, as I said earlier, the ABS and TC has helped me out once or twice.

I live way out in the countryside where single track roads, tractors, caravans and farm animals on the roads are often the norm. Yes, I've been pushing it and suddenly been confronted with any of the above. I've been guilty of grabbing a fistful too, on at least one occasion. Who hasn't? Did the ABS save my neck? Who knows for sure, but I was glad it was there. Do I ride thinking that the ABS will make up for poor ability or stupid risk taking? Of course not.

TC? I've hit a patch of mud or a wet drain cover on a bend before and the TC had cut in (was on highest setting at the time). Did it save my bacon? Again, who knows? But it certainly is nice to know it's there, looking out for me and possibly helping in situations that may be unavoidable.

I came into biking late in life. Of course, I wish I had bought a bike years ago and learned the art of riding and developed my skills throughout my adult life but I didn't for one reason or another. Of course I am capable but I generally ride safely and am open to any device that makes the whole experience a safer one.

Yes, I've bought all the safety equipment available and often paid silly amounts of money for it. Of course, when the chips are down, no amount of safety devices will avoid the inevitable but in my head I feel much better prepared when getting on the bike. And no, it doesn't make me think for one second that these features make me indestructible or faultless.

Biking is inherently dangerous and that fact is unavoidable but why should I, or anyone else, be ridiculed for purchasing a bike with TC or ABS when its purpose is to reduce risk? Wether or not it will keep me alive longer or make up for lack of experience or ability is not even brought to question here...we all know the answer to that one.

I was actually ridiculing you for being so self-riteous about it. I couldn't give a damn if you have ABS or not.

That was not the point I was making. What I was saying was that, statistically, some collisions happen on the road because the rider did not brake hard enough for fear of locking up, or whatever, when if they did brake hard enough the impact would not have occured.

I am not talking about routinly using it, I refer only to emergency stops, which is the only reason I would use it, as I don't think I will ever ride for outright performance etc.

Personally I don't think you (or anyone else) should have any right to decide whether I wear a helmet or not. It's up to me, not you, and the same goes for rider aids as well.

IIRC the penalty for not wearing a helmet is a £60 fine and no points.

+1.

If I want to ride a helmet, I should be allowed to. Give me a higher insurance premium if you must (which might make me wear a helmet) but to make it against the law is silliness.

2 years ago when I went to India, 1 in 5 people on motorbikes would be wearing helmets - on what are possibly the most dangerous roads in the world - when I went back last summer, it was more like 3 in 5, there has always been a law about wearing a helmet, it's just being enforced now. Tis sad to see, even India, a place very much removed from the "health and safety" state of mind, where if you want to engage in some ludicrous behaviour and kill yourself, you are very welcome to, even India is going that way.

But then you always have the option of slipping the policeman who stops you 20/30 rupees (how much it costs for a bottle of water) and he will send you on your way with a smile Laughing
