 Posted: 23:38 - 23 Sep 2023 Post subject: ABS is evil? |
 |
|
Ho-hum, another Fortnine video:
https://youtu.be/sDbWZiaUeDY
tl;dr If you know how to brake properly then ABS is a hinderance.
Nothing revelatory in that statement but the video continually says: "in an emergency most people only slam the rear brake" supposedly because they're scared of flipping the bike by using the front. Is this actually the case?
I've said it before but if I see an orange light and there's no one behind me I use it as an emergency brake testing exercise. Obviously it'll scare the shit out of the pedestrians crossing at that point but fuck 'em Anyhoo, I've always found it best to use both brakes - how odd - and I've surprised myself how sharp you can stop without losing control and without the ABS kicking in.
"Yeah but in a real emergency you wouldn't do that!" Right, so the thing you've practiced over and over you wouldn't do instinctively, gotcha  ____________________ Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |

Mind you, the traffic officer who confidently stated they'd only used the rear brake seemed to be basing it on the fact he'd only seen rear tyre skidmarks.
Well, if you looked at the road after pretty much any emergency stop I've done, that's probably what you'd see because I commonly lock the rear under very hard braking, even if I don't touch the brake because there's no slipper clutch on that bad-boy and the rear tyre is probably hovering just off the road. I do on occasion lock the front too but usually come back off the brake pretty quick when I do.
The whole being able to steer while under hard braking rationale makes sense in a car but not on a bike. Motorbike tyres are extremely grippy under braking and acceleration force OR under cornering force. Not both at once. Start cornering while braking to the grip limit of the tyre and that grip limit will lower. Your ABS will compensate by backing off the brakes.
I find my reaction in an emergency stop, having never ridden with ABS, is to brake as hard as I can in a straight line then if it looks like I can steer round it, do that once the speed has bled off OR just steer round it if it looks like I can do that. Trying to do both achieves neither very well. If a collision seems inevitable, braking as hard as you can in a straight line is probably the thing to go for, it's scrubbing as much energy out of the collision as you can before you hit. ____________________ “Rule one: Always stick around for one more drink.

Thing about laying a bike down is it'll decelerate WAY quicker on its wheels even under 70% braking than it will sliding on its side or you sliding on your arse. Stay on the brakes until you hit. If you laid it down and it didn't hit, you could have stopped it on the brakes.
Only real good reason for laying a bike down deliberately would be if it had undergone a catastrophic loss of control due to a mechanical issue or road surface issue. Only time I can think of where I deliberately laid one down was when I hit the point on the A66 where the snowplough driver presumably decided to go off shift (can't say they stopped because it was impassable because I rode a freshly crashed VFR750 over) and abruptly went from doing 50mph on black tramac to 8" of fresh snow. On the third weave, I got off when it weaved towards the kerb side. Got 10ft further than the following car who landed up nose first into the central reservation. ____________________ “Rule one: Always stick around for one more drink. That's when things happen.

ABS on my KTM was always switched off. It was a hindrance on that bike because it was made to be a tool on the road, couldn't do skids or stoppies. It was on by default next time so you had to turn it off.
My BMW, I wish it had abs, it's been disabled by previous owners. It's a heavy lump to stop and end up having to put more than I feel I should. Could just need better brakes though..  |

Traction control in cars is a fucking pain in the arse a lot of the time. I've been stuck on a wet tarmac slope in a RWD mercedes vito before until I turned the ESP off.
My current Nissan van will grind to a halt and refuse to set off again on gravel roads if I leave the traction control on.
Both ABS and traction control on cars are a liability in snow. I doubt they'd be much better on a bike. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

Having ridden a few bikes with ABS I can comfortably say I fuckin hate it. the pulsating feels horrible and I feel like I cant get a gauge on grip on the front whilst ABS is activating.
That said, as much as I could take or leave it if i was buying a new bike, Im not enough of a fool to say I can outbrake ABS with a non ABS system. ____________________ own: 81 xs1100g...

stinkwheel Well I just had my hands up a pigs fanny. Which makes your concerns pale into insignificance. |

And it works. It works because you need to be able to steer to keep a bike upright. A bike will fall on its side if it can't steer into the side it's leaning into. If you brake hard enough to lose traction on the front, it's not long before the bike falls on its side. So even before you think about steering around an obstacle, ABS helps by keeping the bike upright.
Once upon a time I was riding my old SH300 on a rainy day in Islington, a little bit too fast to stop comfortably, and I applied slightly more brake than the surface conditions would allow. I found myself for a moment or two in a peculiar state of drifting diagonally. I was braking hard enough that the rear was slipping a little, I was steering into the turn to compensate as is second nature, and the ABS was making sure all the wheels kept turning, so that I was in control of the vehicle even while it shed speed as much as traction allowed.
This ended up being a minor blip on my journey. I didn't need to release brakes, recover, then gingerly reapply them in knowledge of reduced traction until I came to a gentle stop in front of an obstacle. Instead, the ABS measured the available traction for me, and all I had to do was keep the bike upright. It was considerably less stressful than it might have been. ____________________ Bikes: S1000R, SH350; Exes: Vity 125, PS125, YBR125, ER6f, VFR800, Brutale 920, CB600F, SH300x4
