Q & A
What is ABS, and how does it function in vehicles?
-ABS, or Anti-lock Braking System, is a safety feature designed to prevent wheel lockup during braking. It uses sensors to monitor wheel speed and adjusts braking pressure to maintain traction, allowing the driver to retain steering control while braking.
How does motorcycle ABS differ from car ABS?
-Car ABS is more advanced due to the four-wheel setup, where each brake is independently controlled by a four-channel ABS system. Motorcycles, however, have two wheels with significantly less contact with the ground, making the braking dynamics more sensitive to weight transfer and rear-wheel lockup.
What are the phases of ABS activation during braking?
-There are three phases of ABS activation: Phase 1 occurs during normal use when hydraulic pressure is applied to the brakes. In Phase 2, the ABS pump intervenes if it detects a slide, holding braking pressure at a safe level. Phase 3 happens if a wheel locks, and the system releases pressure to restore traction.
Why do many motorcyclists use only the rear brake in an emergency?
-In emergencies, about 80% of riders instinctively use only the rear brake due to fear of flipping over the handlebars or losing control. This reaction is often hardwired and leads to inefficient braking because the front brake provides more stopping power.
What is threshold braking, and how is it different from slamming the brakes?
-Threshold braking involves applying the brakes in a controlled, two-stage manner, allowing the front tire to build traction as the weight transfers to it. Slamming the brakes, by contrast, puts the ABS into crisis mode, causing it to constantly adjust and reducing braking efficiency.
Can a skilled rider outperform an ABS system during braking?
-Yes, a skilled rider can sometimes outperform ABS, particularly when using threshold braking. A human can anticipate weight transfer and apply braking pressure more strategically, whereas ABS is reactive and may prioritize stability over maximum stopping power.
Why is ABS still considered a critical safety feature despite its limitations?
-ABS is statistically proven to save lives because it reduces the likelihood of wheel lockup, helping riders maintain control in emergency situations. While a skilled rider can sometimes brake better without ABS, most riders benefit from ABS as it compensates for common mistakes.
What common braking mistake do motorcyclists make in crashes?
-Many motorcyclists fail to use the front brake or use it improperly in crash situations. In about 80% of serious motorcycle crashes, riders either don't brake at all or rely solely on the rear brake, which offers much less stopping power.
How does ABS handle braking on surfaces with limited traction, like ice?
-ABS can extend stopping distances on surfaces with limited traction, such as ice, because it constantly releases and re-applies brake pressure to prevent wheel lockup. This process is similar to driving an old car on ice, where braking control is more difficult.
What practice is recommended to improve emergency braking skills for motorcyclists?
-Riders are encouraged to practice threshold braking, which combines controlled use of both the front and rear brakes. This helps develop the instinctual ability to brake effectively in emergencies and maximizes the benefits of ABS without simply relying on it.

🏍️ Motorcycle ABS System Explained
The script discusses the modern Anti-lock Braking System (ABS) on a Honda motorcycle. It explains that despite the common belief that one should brake gently to avoid locking the wheels, the ABS system allows riders to slam the brakes without worrying about skidding. The script introduces Ryan Austin, a retired police sergeant and crash investigator, who explains that most motorcycle crashes occur due to poor braking, not speed. He notes that while the front brake is more powerful, many riders instinctively use only the rear brake or freeze in emergency situations. The script then delves into how car ABS systems differ from motorcycle ABS, with the latter being more complex due to the need for individual control of each brake. It describes the three phases of ABS operation: normal use, emergency use where the system senses a potential slide, and active shedding of brake pressure to prevent wheel lockup. The script concludes by suggesting that while ABS can be outperformed by a skilled rider using a two-stage braking technique, it is still a lifesaver in many situations.
🛑 The Importance of Proper Braking Technique
This paragraph emphasizes the importance of learning and practicing proper braking techniques on motorcycles, especially when equipped with ABS. It points out that while ABS is designed to prevent wheel lockup and maintain control, it can be less effective than a well-executed threshold braking technique. The script explains that threshold braking involves a soft initial pull followed by a harder pull once the bike's weight is transferred, which can be more effective than simply slamming the brakes. It also notes that ABS systems prioritize steerability over straight-line stopping distance, which can be a disadvantage in certain situations. The script concludes by encouraging riders to practice their braking skills to improve their safety on the road. It also promotes the use of proper riding glasses for better visibility in emergencies, with a shoutout to Flying Eyes for their commitment to safety and the quality of their products.

Transcripts
hello and this Honda is equipped with a
modern ABS system so forget threshold
braking and just slam the pedal and this
computer will stop itself faster than
you can say Fabio carteraro oh
[Music]
what just happened is so scandalous I
worry you'd never believe it from me so
I've baited a professional to explain
I'm Ryan Austin retired police sergeant
major crash investigator
[Applause]
I don't see any skid marks really common
in motorcycle crashes we see 80 percent
of riders involved in serious crashes
either don't break at all or break with
only the back brake we've seen this
through thousands of crashes over the
years it sounds ridiculous every
motorcyclist in their manicurist knows
the front brake has more stopping power
and will use more of the front brake in
daily use however when thrust into an
undaily situation an impending Collision
that will definitely hit and the only
question is how fast that's when a hard
wire in our toddler brain takes over
eighty percent of us go I can't pull the
lever that hard or I'll Endo this big
wheel so we either freeze or slam just
the pedal like a car driver
speed's not the cause of most motorcycle
crashes it's bad braking if everyone
drove around at 200 kilometers an hour
but never crashed in anything why would
I want to write tickets for that it's
not the speed it's bad braking and lack
of practice but that's what ABS is
supposed to fix right it's supposed to
make any meatball a pro level breaker
right well first let's realize the car
ABS is dissimilar and this monstrosity
has four wheels and a combined contact
patch bigger than my inferiority complex
and there's one idiot pedal to engage
all four brakes get a four Channel ABS
system that articulates each
individually to maximum effect
whoa not even the soap opera stars from
F1 could outbreak car's ABS system
but on the motorcycle
[Music]
we're going to test front braking too
but the only way you'll believe the
results is if we first understand what's
happening inside your little puddle here
normal use the lever pushes hydraulic
pressure which flows straight into
pinching the pads
phase one emergency use the wheel's
speed sensor goes damn that's a slide
risking amount of D cell so now the ABS
pump closes its upper solenoid valve
blocking off the lever and holding your
braking pressure at its current level
this is phase two now if our wheel
continues to decelerate and locks the
ABS pump opens its lower solenoid valve
allowing this release circuit to bypass
brake fluid back to the reservoir now
we're actively shedding brake pressure
until the wheel accelerates again this
is phase three
solenoid valves are incomparably fast
your control module can cycle through
all three phases in a tenth of a second
which is faster than a meatloaf can even
register a slide so how did we beat abs
while slamming the rear pedal
immediately puts our ABS system into
phase three that crisis mode bleeds
braking pressure every hundred
milliseconds and when you subtract all
those increments of no breaks you get a
shorter stop every Canadian is familiar
with this and drive a hunk of junk
through winter Peg and you'll quickly
realize the ABS stopping distance is
halfway to Moose Jaw motorcycles are
very much like an old car on ice and the
weight transfer is so severe there's
only five ten pounds over the rear wheel
so the available grip before lock up is
minuscule however the opposite is true
for the front wisdom on threshold
braking says to do a soft and hard lever
pull because the tire can withstand more
braking Force once the weight is
transferred onto it here we're doing
exactly that slamming both levers with
ABS on versus threshold braking with abs
off
two things are happening and the early
moments our ABS is forced into that
third phase lest we lock the front
before it's loaded in the last moment
ABS is again entering crisis mode to
prevent this stopping
see humans can do stuff the computer
can't for one we can predict that atar
will have less initial grip than when
it's loaded by weight transfer and we
can make that two-stage lever pull
whereas ABS is only reactive the
computer must see a slide before it can
make an adjustment second a human can
weigh the consequences of their maneuver
if knocking up a 12 o'clock stoppie
means not hitting the bus I'll gladly do
it whereas ABS systems always prioritize
steerability and they will sacrifice
some straight line stopping distance if
it means keeping the rear grounded The
Unbelievable Truth is that you can
outbreak your ABS system sometimes
nope
I can afford these mistakes in
repeatable skid pad tests but not in the
once for a lifetime moment of a real
world's crash and that's why ABS is a
statistically proven Lifesaver in daily
use and I would never recommend
disabling yours but
you don't have to we know slamming your
abs into phase three is worse than
threshold breaking but threshold braking
should only correspond to the first two
phases meaning you can achieve very
nearly the best stopping distance with
abs left on
summarily when faced with an impending
unavoidable impact the average Rider
will only break with the rear but the
average Rider can learn to instinctually
combine threshold break and the average
ABS system will benefit from that versus
simply slamming the levers so don't be
average go practice and save your life
thank you very much to Flying Eyes and
their commitment to safety that made
this PSA possible look at all these
colors look at all these shapes look how
they slide easily into any helmet the
reason Flying Eyes offers all this and
lifetime warranty is all this is because
I think everyone should have a proper
pair of riding glasses shatterproof
polycarbonate and your prescription
bifocal if need be because you can't
break for the Emergency if you can't see
the emergency
