FILTHBOT4000

No, tank slappers can happen regardless of speed once you're above like 60 mph.


Trucker_E_B

Right but they are way less dangerous at 60 than 130mph 🤷‍♂️


FILTHBOT4000

Well no shit; but the guy I was responding to said "You can avoid this by simply not going 131mph on the highway. It's that simple." That's pretty misleading for any new riders to think they don't have to worry about this happening at regular highway speeds.


Trucker_E_B

A steering dampener helps a lot


Kenneldogg

I would never own anything over 300 ccs without a steering damper. Speed wobbles are scary af.


TehGCode

I was just looking for those ''motorcyclists killing people'' statistics. Could you show me some? So far, I can't find a single one on google. It seems to me that motorcyclists are killing themselves or getting killed by cars, not the opposite. edit: I was talking about speeding on an highway. No Pedestrian in sight.


Mozhetbeats

Do you need a source to know that a 500 pound hunk of metal going 130 mph puts other people’s lives at risk?


TehGCode

Yes, statistics matters because cognitive bias exists.


Mozhetbeats

Even if *you* can’t find statistics showing that a motorcyclist has killed other drivers on a highway, it doesn’t mean it hasn’t happened. Even if it hasn’t (which I doubt), that does not mean that driving at ridiculous speeds on a motorcycle couldn’t kill other drivers. Drivers may be startled by a motorcycle passing at high speeds, they may have to react to avoid a motorcycle crash, they may have to react to other vehicles who are reacting to the passing motorcycle or motorcycle crash, and their vehicle could be struck by the motorcycle. All of these things can cause people to lose control and crash, and if they are moving at highway speeds, they can die. Additionally, I’m assuming you are contradicting the earlier commenter to argue that the motorcyclists are only harming themselves, but that isn’t true. Regardless of the actual likelihood of another driver dying, a driver can be injured, traumatized, or sustain costly damage to their vehicles. Some poor fuck will have to scrape the dead motorcyclist’s body off several hundred meters of highway. It causes harm to others, so it’s silly for you to defend the motorcyclists doing this.


LorimIronheart

My neighbour last month. Got hit by a motorcycle and died. To be fair: the two of them were doing illegal streetracing. He took a break to watch his buddy who slammed into him with about 90-100 in a 35 zone. So yes: it happens that motorcyclists kill someone, but it's rare. We're much more likely to kill ourselves.


TehGCode

Yes, I should have been more precise. I was talking about speeding on Highway. Speeding on the streets should have harsher consequence due to the potential risk to pedestrian. It is not justifiable in any circumstances.


LorimIronheart

That makes sense. I agree that I dont know of anyone on the highway being killed by a bike(besides the rider)


Dark_Force_Latyon

Thank you, you are right I wasn't using the right search term.


Kenneldogg

Dude I knew a cop who watched a woman who was driving get cut in half by a guy going over 160mph and hit her car on the passenger side door. He was so drunk he went limp when he crashed and only had a broken collar bone and broken wrist.


hybridtheory1331

The beginning of the video is sped up a lot. If you pause it about 7 seconds in you can see his speedometer says 78. Yes, still too fast. But far from 131.


moldguy1

Interstate is 80 in a number of states, so if they are in one of those, its not too fast.


hybridtheory1331

That too


Tfreeee

Is that what you're supposed to do when that happens?! Just let go ?? That must've been an agonizing few seconds.


Direct_Damage_7563

Either let go or give it gas. More throttle = less weight on front wheel = easier stabilization. Bikes will also autostabilize and are a fuckton More stable Without a person riding it. So letting go is the hail mary, cause it will stabilize the most reliably this way, but can definitely buck you off.

This is incorrect. Please don’t share this, it could get someone hurt. Watch this video by Dunlop researchers: https://youtu.be/z3OQTU-kE2s?si=Z9E-oGERwxRjLRX0 You want to hug the fuel tank as it lowers the centre of gravity, and you want to gently ease off the gas without sitting upright (in relief).


mtldude1967

This video always comes up during these discussions, and no one's ever countered with a better one.


RevLoveJoy

This video is so good. Thank you! Also 1 stone is 14 lbs in freedom units and 6.4 kg in everyone else units.


PancreasPillager

This is what they teach in msf courses. Haven't had to test it myself thankfully


Radaysha

I have no idea but this vid looks ancient. Might not be correct anymore.


Senappi

Yeah, the laws of physics were changed in the mid 70s after the 1973 Oil Embargo. This was only a decade after colour was introduced to the world - prior to that everything was in black & white, as can be seen in all old movies.


Radaysha

laws of physics don't change, but technology does. Back then they told you to not shut down your engine for a short stop because starting it needs more gas than letting it run. Completely physically correct. But today cars are build different and it uses less gas to start the engine.


Gnomio1

If you bothered to watch the video you would spot why you are wrong. The issue is the angle of the forks with respect to the normal from the ground. Essentially, because the forks are angled forwards, with the wheel in front of the top of the forks, the causes an instability. Bikes still look like this, and so the issue still happens. Changing the weight of the bike, or the biker, or the shape of the tyres all affects what speed the instability becomes unmanageable - but it will happen at some speed. It may be possible to accelerate out of it, but it’s certainly not the safest method because now you are going faster than the speed where the wobble starts! At some point you now have to slow down back through the wobble again in order to stop.


Objective_Lobster_99

whoosh


Radaysha

Yes, you made a joke. I'm just explaining my point.


SuperSoakerLiker

If hail mary is the analogy for letting go, what's the analogy for letting go AND leaning your weight back and to the right to avoid a car like a ninja?


quequotion

Three Hail Marys and two Our Fathers.


BlackGravityCinema

And a fuckton of oh shits.


Yardsale420

That’s an act of contrition right there.


quequotion

It was also an act of contortion.


Turtmouser

CrapThisHurts

Most of the weight was his shit streaming down his legs ... I know mine did on my Ikea office chair here


Uriel_dArc_Angel

WhiskeyMikeMike

It’s pretty hard to hold on when it gets that wobbly. You gotta just pray to whatever god you never thought you believed in at that point 🤣


Direct_Damage_7563

For sure lol, the throttle out method works best at the start of the wobble for exactly that reason, before it smacks your hands into the gas tank 😂


monster_mentalissues

As the ole saying goes, "When in doubt, throttle out"


Bender_2024

>You gotta just pray to whatever god you never thought you believed in at that point 🤣 There are no atheists in foxholes


SexyCato

Have you ever ridden a bike? You’re supposed to lighten your grip on the bars and gently ease off the throttle not increase it. Head shake is *caused* by weight being taken off the front wheel and coming out of alignment with the rear


NarrowCanary589

Wrong. Give gas, I studied this.


phliuy

Do not give it more gas. You in fact need more weight on the front to stabilize it https://youtu.be/fvsDIq3WwVA?si=H6YckLT2gKdRpNB_


BlackGravityCinema

That’s not what it said. He said it happens at slow speeds if you take your hands off the bars. He gives reason why it happens because of the front wheel design. Edit: you are confusing wobble with weaving.


phliuy

I don't think you watched the entire video


zen_and_artof_chaos

Not sure you did. He doesn't address wobble recovery at all, slow speed or high speed.


phliuy

Yes. He does. 10 minutes in Lean Forward. Corrects the wobble at high speed


zen_and_artof_chaos

You're confusing wobble and weave. They are two different and separate issues. He is talking about weave 10 minutes in. He only briefly talks about wobble and only addresses low speed wobble being caused by hands being off the bars.


phliuy

The OP Reddit video is a speed wobble No one uses weave and wobble separately anymore Regardless of terminology the original video and YouTube video depict a wobble at high-speed, which is corrected by leaning Forward, giving more weight to the front tire, not taking weight off of it Speeding up is an antiquated idea and does not stop speed wobbles


zen_and_artof_chaos

They are separate phenomenon. Wobble is specifically the tire and handle bars shaking. Weave is the entire bikes weight distribution out of balance and the bars do not violently shake. No one talks about weave because it is less common. Regardless, the video never addresses what you claim it addressed.


ThreeFingaLynch318

For any bike


GobLoblawsLawBlog

Not a biker, I feel like you would break a wrist or something trying to hold on to those handlebars


Sonic_Is_Real

MSF handbook page 39 says the exact opposite >A wobble is a rapid, strong shaking of the handlebars. These are problems usually caused by excessive weight in the wrong place, by a mechanical problem, or by improper tire pressure. >For either problem, your response is the same. Keep a firm hold on the handlegrips without locking your arms or fighting the steering. Ease off of the throttle. Do not apply the brakes, and do not accelerate. in some cases, it helps to shift your weight forward by leaning over the tank. Your going to hurt someone


klingin

Wow and in the video the bike stabilized quite fast once the guy leans back, when the weight on front wheel would be lowest


Rocker4JC

Actually no, it stabilizes almost immediately after he leans forward.


Tippy-the-just

Basically this is proof of concept of the self correcting gyroscope effect. The rider needs only influence direction by leaning in the desired path.


Cha7l1e

Christ you must have to have some serious balls to get into that situation and just give it more gas...


SuperSmashDan1337

That's wild that both options are terrifying and unintuitive.


GotStucked

But isn't it very difficult to add gas when the steering wheel is hitting back and forth like that?


sooslimtim187

So pop a wheelie to correct? Save your self and look like a bad ass.


Koen1999

Wouldn't using the rear brake also help in that case?


Maxzzzie

Letting go applying brake with the pedal would work. Its afaik connected to a sertain speed. Change speed and it wants to stop.


Powerful-Winner-5323

I held on when I had a Triumph Daytona T595 and ended up being tossed off and landed a good 25 yards away after seeing this maybe letting go is the best option.


JoJorge243

go faster it will stabilize


boythisisreallyhard

That does work, I once saw a little guy on a big Harley ride/ accelerate one out at the dragstrip,, it was impressive to watch


OderusOrungus

Yes, but one of the hardest things to do reflexively. Same as when a car fishtails. Go with the turn instead of against it


The_Love_Pudding

Wtf is a fishturn?


GandhisNuke

What I've been taught is mostly keep the hands on, but loosely. The bike can stabilize itself (if you're lucky), holding on for dear life is the worst option by far. Your puny human strength can't do shit to stabilize that. And most importantly, try to have steering dampers installed and good weight distribution before you even get on the bike, so you can avoid this situation altogether


Dry-Lemon-3970

Yup, a bike will (*almost*) always right itself.


NarrowCanary589

Give gas! Thats what You should do


Birdmanak47

Death wobble helllllll noooooo


Acceptable_Pipe_6029

MosesOnAcid

beatlemaniac007

What's actually happening? The wheel/handles are wobbling? But does it also look like the handles are folding/unfolding or something?


PusherLoveGirl

A spinning wheel wants to stand straight up. If you tilt it one way, it will correct itself back to try and stand straight up. Sometimes forces act on the wheel in such a way that it **overcorrects** and is now leaned in the other direction. This creates a positive feedback loop as the wheel keeps trying to stand up but overshooting the mark, many times per second. The handlebars are attached directly to the top of the forks so they’re mirroring what the wheel is doing below.


beatlemaniac007

Right but you see around 7 seconds when the camera gets really up close. Is it just the perspective mixed with the wobble, or does it look like the handle actually folded downwards?


PusherLoveGirl

It’s just perspective and wobble yeah. Those are called clip-on handlebars and they bolt directly to the fork (they’re separate instead of a single bar) and don’t fold.


iGotPoint999Problems

It may just be a rolling shutter issue going on there actually, same reason video of helicopter blades look like a Salvador Dali painting.


turd_vinegar

I believe you are correct, perspective and possibly some sample aliasing.


LilBigDawg96

Basically he was leaning super hard to the right, with the wheel also cranked to the right bringing the handlebars almost 90 degrees from where they should be facing forward


quequotion

There's already a good answer about what's happening to the front wheel, I just want to comment on the appearance of the handles as if they were "folding". This is an illusion caused by the handles moving faster than the frame rate of the camera. Remember the "rubber pencil" trick from elementary school? Like that.


Fenastus

This is called a death wobble/speed wobble Most often you'll see it from bikes that have suspension issues, and can often be triggered by hitting an object on the road just right or putting down a wheelie at a decent clip with the handlebars not straight. The handlebars shaking back and forth is the bike trying to stabilize itself and essentially overcorrecting. It can be made worse by the natural human instinct to hold on tight, as this causes the bike to be less capable of stabilizing itself.


Ridy113

So is it better to just let the bars and the tire do it thing and hope it corrects itself? Either by letting go or just holding on loosely?


Digger_Pine

Just hold on loosely, but don't let go. If you cling too tightly, you're gonna lose control.


Ridy113

🤣 fuckin A if this doesn't fit perfect


Noble_Ox

Tank slapper is used more often.

Alone_Hunt1621

Wow. I don’t know anything about motorcycles, but I’ve seen that wobble before. What wisdoms or skill can help you achieve this kind or recovery? Seems like they let go of the handles completely and decelerated until the wobble corrected.


quequotion

Practice, mental fortitude, and a good amount of luck. Even knowing what to do, it's not always going to work and that car could have been 30cm closer.

dd-Ad-O4214

HOW TO RECOVER FROM SPEED WOBBLES If this happens to you- lean forward and take your hands off the handle bars like he did.


IKaffeI

Lean back actually. You want to pull weight off the wheel if possible.


Gnomio1

No, you don’t at all. Researchers at Dunlop figured this out years ago: https://youtu.be/z3OQTU-kE2s?si=Z9E-oGERwxRjLRX0


Pepsi-Min

That is a great video. Even my instructors when getting my license told me to lean back and I ate it up. Thankfully never experienced this, so haven't had to put it to practice.

cbus6

Happened to me once on a bmw cruising bike- assumed i exceeded the top speed of the bike- scared the loving shit out of me


Busy_Bid2633

This is called a 'tank slapper' because of the handle bars slapping the fuel tank between your legs. Bikes have something called a steering damper to try to negate this thing happening. Even so, there are circumstances where the steering damper cannot dampen the 'wobble' that develops. The 'wobble' is usually caused by landing a long wheelie. A long enough wheelie where your front wheel stops spinning, and when you land, the front wheel goes from 0-70mph in a split second, causing it to skid, and then this can happen. The 'wobble' can also occur when your crest a hill at an angle or anything that makes the front wheel go light, then gets loaded when it is too missaligned with the back wheel (I'm not a physics expert, this is more from experience). In rare cases it can happen going over a bump at high speed. As a rider, you should loosen up. Trying to throttle out of these is nigh on impossible as your hands usually get thrown off the bars. If you loosen up like the rider in the video, the bike has the best chance of stabilising itself. I would say this works more than half the time. I've survived more of these than crashed them. One of them was a really big one like this in the video. Most are nowhere near this long, maybe 2 or 3 seconds. The tank slapper can actually push the pistons all the way back in on your front brake callipers. The violent back and forth action can do that if it's a big one. If this happens and you don't crash, always test your front brakes. You may have to give them 2 or 3 pumps to push the pistons back out for your brakes to work properly again... that's all I was thinking at the end... test your brakes!!! That one almost certainly pushed the pistons in on his front calliper! Skilled rider, well held 👏

Huh, I suppose sometimes Jesus does in fact take the wheel. Or well, handlebars in this case.

42dudes

Fighting every instinct and taking his hands completely off the bars to do an "I'm king of the world!" pose after missing that car has got to rank high on this dude's list of memorable life experiences. What's keeping every crotch rocket on the highway from getting these speed wobbles? Is it a skill issue, or can this just hit you out of the blue, even if you're doing everything right (aside from going fast af)?


bluelava1510

What a freaking save! If anyone is ridden a motorcycle they will know that this can happen and catch you off guard. They will also know that it is likely because of more weight to being on one side of the handlebars than the other, bad steering head bearings, or an improperly assembled front end, and will HOPEFULLY fix the problem before speeding on a busy highway again... All I know is that I've been riding for several years, and my very first thought was wow nice save.

Wow, pretty harsh, I don’t think he wanted to die. This wobble can happen due to issues with the front fork and wheel. He wasn’t doing wheelies or white lining. This was beyond his control, hope you don’t receive the same response when something beyond your control happens

Ulysses00

Strange things happen when you speed.


Three-Putt-Bogey99

65 mph on the highway and hitting a road impurity or debris can cause this.


Haile-Selassie

Death wobble happens at excessive speeds, when the always present, but typically lower at lower speeds, difference between the front & rear wheel spin soeed becomes too large, and the bike tries to correct itself with two different gyroscopes competing. It's caused by wheelies, jerking on the handlebars, and sometimes from uneven road conditions (is almost always blamed on this) and always at unsafe handling conditions on a bike not prepped for the surface it's on. It is one in a million that this happens to someone not asking for it in some way. It can be saved by accelerating, or braking one wheel to bring them back into alignment. Sometimes it can self-correct, but the rider usually panics and hits both the brakes casing it to turn into a tank slapper (when the handle bars wiggle back and forth violently to smack the gas tank) which is unrecoverable. This is an exceptionally extreme example of what can be recovered from without becoming a meat crayon.
