I'm trying to figure out what made him start to wobble. There's nothing visble, the only thing I can think is side winds?


Naevos

I'm original post comments say he was speeding and popping wheelies.


[deleted]

It was probably a good old tank slapper


rageblind

Yeah. I had a 2004 zx10r was prone to them. Accelerating in 3rd the front would lift for a split second and start off what were thankfully bad head shakes but weren't far off a full blown tank slapper.


[deleted]

Did you ever try a steering damper?

TwoPond

I’ve sold bikes for that exact reason lol, poor right handle control, couldn’t resist the temptation! And I only ever had 600s but the temptation was to real, sold it before I ended myself!


Mcmelon17

Sold mine yesterday for the same reason😢


TwoPond

Having kids made Me realise I need to calm the fuck down lol


jimson69

I crashed mine on the commute home from work... to be fair I was being a dick speeding and weaving through traffic. Came off at 75kph, fractured wrist and grazed hands. Still, saved me from dying on the freeway... I have no self control.


Miturtleessuturtle

Yikes, that’s almost exactly the speed I was going when I totaled my first car and it did a lot of damage to myself and the vehicle — I can’t *imagine* doing that on a bike!


jimson69

Yeah I was *very* fucking lucky. I'm getting another bike soon... hopefully I've learned my lesson but I guess we'll wait and see


[deleted]

Ah fair enough


VTCHannibal

> nothing to stop you dying other than a bit of self control lol. Like all bikes


pm_mba

Owned one of those completely agree.

Steering damper

Nah dw. Thanks for that


gotham77

We both speak the same language, and yet this was incomprehensible to me.

EarlyForest

I’ve only ridden cruisers. Could you accelerate hard to get the front wheel back off the ground to stop the slapping? I realize that would be difficult with it slapping.


[deleted]

[удалено]


EarlyForest

Mine are over a foot above the triple tree so I can’t imagine stopping it on my bike. Though I think it’s less likely on a cruiser.


rageblind

Yeah bike geometry, suspension etc all play a part. I'm sure they happen, albeit less often


sidewinder15599

I found out in heavy traffic that my 81 Goldwing is capable of popping up. Cruisers can definitely get up.


EarlyForest

The gold wing is sort of a different beast though. I don’t imagine you can pop an Electra glide or vtx1800.


sidewinder15599

Oh! I figured with the same rough weight and far more power you could. Mine's only a tired old 1100.


ekaftan

Lifting the wheel won't fix the slap. You need to increase weight on the front wheel and slow down. In a cruiser, if you get a tank slapper, let go of the gas and press the rear brake.


EarlyForest

No I’m saying off the ground. Like pull in to a wheelie and then make contact again.


Kareemofwheet

Late to the party but you abso-fuckin-lutely do NOT brake at all and you SLOWLY decel.


ekaftan

I agree you never touch the front brake... but why not the rear? The goal to stop a tank slapper is to shift weight into the front wheel... right?


[deleted]

How does that work? Wouldn’t hitting the rear break take even more weight off the front wheel?


ekaftan

Pressing the rear brake shifts weight to the front wheel.


Mons7er

That’s the bike I had! That is an amazing bike! Very exciting.


UnknownParentage

I still have a 2005 ZX-6r. The Kwakas of that era had aggressive geometry but weren't fitted with dampers so I have the same issue. I also get the start of a head shake if I hit a bump when leant over and I'm holding the bars too tight.


rageblind

A c1h? That's a great bike. I had a b1h 6r, test rode a c1h and it's a much better road bike. Ohlins damper on my 10 did help a lot of you are thinking of investing.


UnknownParentage

I still love it; I could get something newer but just can't justify it as it is just good to ride. A steering damper isn't really justified anymore for me though as I've stopped doing track days, and headshake is only a problem when I grip the bars too tightly.


David_Jonathan0

What’s a tank slapper?


[deleted]

When you accelerate, sometimes the front wheel lifts off the ground slightly and when it comes back on the ground it turns left and right violently. Usually you just have to ride it out.


David_Jonathan0

Not something we granny riders have to worry about yes?


dfwnerd

It can happen on a cruiser. I had this occur on a 2014 Indian Chief Vintage. We picked up a piece of debris in the front tire (unnoticed before the accident) and over the course of 70 miles or so it slowly went down until the pressure got too low. It started as a weak shimmy in the front end and progressed to a full-on tank slapper in a few seconds. This was at 80mph on I-10. i think we got down to about 65 before the bike flipped and we were launched from it. We now ride a Roadmaster with TPMS.😁


David_Jonathan0

TPMS FTW. Every bike should have TPMS. A simple kit is like $50 on Amazon.

[deleted]

😅no. They are more common on certain bikes and you can get steering dampers which reduce their effect.


EdwardTennant

Yes there was a specific model of harley which was prone to failing headstock bearings, that with the steering geometry being funky gave that bike a much higher chance of getting into a tankslapper


you_do_realize

It happens on bicycles even. But all you have to do here is put your hands back on the handlebars.


UnknownParentage

It can also be caused by other things than wheelies; it is mainly a concern in sports bikes with a short rake angle (so they can turn quickly). On the wrong bike, gripping the bars too hard when you hit a bump can start a wobble.


rromero26

Happened to me in a gsxr 600...sold the sport bike right after...


pikime

Known as the death wobble, happens when your front wheel lands a bit funny and your going to fast to properly recover


Ragnar_Sangfroid

Would pulling another wheelie fix the issue? Of course, assuming you had the time and control to do so.


EdwardTennant

It can do, yes. Generally you want to throttle ouy of it so you can remove weight from the front wheel to allow you to straighten the bars


David_Jonathan0

Because he did a wheelie?


pikime

Yeah Edit: see https://www.reddit.com/r/CalamariRaceTeam/comments/c2tx91/your_worst_nightmare/?utm_medium=android_app&utm_source=share


sublime2craig

Exactly what I was thinking, seen vids of guys doing high-speed wheelies and this happens when they dont put the front down correctly.


DaGhostmeister

I'd recommend watching [this video](https://youtu.be/NsGHbK8McDk?t=136). While a bad wheely landing is a possible cause, it could be a number of other factors, including tyre wear. The video lists common causes for speed wobble at [4:03](https://youtu.be/NsGHbK8McDk?t=240). Also, watch the full crash video [here](https://youtu.be/ezf5oeP3eRE).


[deleted]

He wasn't popping wheelies, just speeding. And he blurred the speedometer for insurance and legal reasons.


citit123

On a grom 125 on a highway? They max out at highway speed, no wheelie power left


bkfst_of_champinones

It’s called [speed wobble](https://en.m.wikipedia.org/wiki/Speed_wobble) and can be triggered by a number of things, like sand or oil or dropping from a wheelie, road imperfections, unbalanced tires, improperly modified bike geometry, excessive speed, and other things. The rider has no idea it’s about to happen. And btw it’s an absolutely terrifying experience.


riverY90

Welp, I've just passed my CBT and am riding this week before doing my A license (full license in the UK). So... Good to know... I'm totally not worried.. at all.


bkfst_of_champinones

Naahhhh don’t worry you’ll be fine. Just have a decent bike that’s properly maintained and unmodified and don’t be riding around like a wanker and you’ll be fine :). Of the two times I got speed wobble really bad, once was in the rain on a bike with a severely unbalanced front wheel, and I had both hands off the bars messing with my helmet. The second time was on a very capable bike, but I was doing about 2x the speed limit on the highway; a highway with some imperfections (cause it wasn’t a GP track ofc), just being a complete teenage wanker. But ever since I started riding like a responsible adult, I haven’t had any problem with it. To be fair though, increased risk is part and parcel of being a rider. As I’m sure you know. I’m not British but I always wanted to use the word wanker so bad and I thought this might be an appropriate situation. Edit: also thanks for using the word welp lol


riverY90

You used the word wanker in the perfect setting, friend! All good tips, I'm 28 so getting on a bike pretty late, at least it's at an age where my brain is developed enough to not be a teenage wanker and err on the side of caution, I would have been in big trouble back then haha


bkfst_of_champinones

:) that sounds very sensible of you. Yeah it’s true, all the real pro riders, in motoGP or MX or any other type of serious riding, started riding when they were five or so. But in terms of being a decent rider for normal street riding, no age is too late. Actually, I take that back. But that threshold is much higher than your age lol. I’m super excited for you, riding is such a wonderful experience!


riverY90

Thanks man! I'm excited too! Always nice to hear from experienced riders to reaffirm my choices haha


bkfst_of_champinones

It is absolutely a great choice if you ask me. Are you planning on doing some kind of celebratory road trip or something? Like maybe over to the next town for a night, idk. Also, I’d recommend finding some riding buddies. Riding alone is great of course but riding with friends is a lot of fun. Or maybe getting into riding is more of a pragmatic choice for you? I’m from the States, but from my limited understanding of UK driving/vehicle laws/restrictions/taxes, and also the nature of UK roads, riding has a lot of practical benefits over cars as well. Is that right?


riverY90

Funny you should ask about a celebratory road trip! One of my main reasons for getting my license is because my bf and I are off backpacking to SE Asia. It won't be a ride trip but it will be nice to have the option to hire scooters (legally and covered by travel insurabce if something happens) at each stop off. I've already got a mate who's been a rider for 10 years and he's introduced me to some of his friends. I'm on the south coast so yesterday we followed the coast over to the next town (which isn't very far, like 20 minutes, everything is a lot closer here than the US). We went back and forth a bit so had a good few hour ride. As for UK roads being better to ride over car. Well, it's not secret we are very congested. You can certainly get to places quicker on a bike than in car. Especially where I live, we are one of the top congested towns, it can take me 45 minutes to get 12 miles to work in my car. Law wise, again it's easier to get a bike. With driving a car you need to pass your theory and practical test before being allowed out on the road. Both these tests are pretty stringent and it takes hours and a lot of money before being independent. Whereas on a bike you can do your CBT (compulsory bike test), which despite the name isn't too much of a test. It's takes about 4-5 hours and suddenly you are allowed out on the independently with L plates. After this test you have 2 years to do your theory and your full A licence or retake the CBT to extend. Some people opt for the matter as a full year costs £7-800, whereas a CBT is just £100-130. So yeah, it's crazy to me that bikes, which are a bit more dangerous, are a lot more lax. But there you have it, it's cheaper and easier


bkfst_of_champinones

That is awesome, you guys are going to have a great time. It amazes me how much more difficult it is to get licensed in other countries compared to the states. Although it makes sense, cause driving is a serious activity and should be given a lot of respect and attention. For me, getting my license consisted of going to driving school (in order to get my permit at 15 instead of 16, but is not necessary to get a license). Driving school included 4 one hour drives with an instructor, and I think about 10 hours in the classroom. I think it cost about $300 or so. The driving test at the DMV is about fifteen minutes and it’s ridiculously easy. Then, to get my motorcycle license (it’s not even a license, it’s called an endorsement and it’s an extension of a regular class C driving license), I took a riding class, which was a course I took over a weekend, half on a bike and half in the classroom. The course cost about $200. I got a certificate after completing the course that essentially said I was competent to ride. I took that certificate to the DMV, didn’t have to take a test, just had to pay $2 to get a new license printed. Anyway, I’m super excited for you, it sounds like you’re going to have an amazing trip!


UnknownParentage

The main cause (other than wheelies) is holding on to the bars too tight on a bike with a low rake angle (where the front wheel is directly under the handlebars). Only sportsbikes are set up in this way (it allows the rider to turn quicker), and these days they are usually fitted with dampers to catch the wobble before it gets out of control. Hitting a bump with a tight grip on the bars can result in the rider magnifying the wobble caused by the bump.


PJBonoVox

Don't worry about it. This isn't a common thing. Try to ignore the 'omg riding is so dangerous, I gave it up' crew as well. They're just out looking for validation on their decision Riding is as safe as you choose to make it.


Rota_u

If you're on a Harley then it can happen for seemingly no reason. Common manufacturing defect for the brand. Nicknamed the [Harley Wobble](https://showmemotorcycles.com/harley-wobblewhat-it-iswhat-it-does-and-how-dangerous-it-can-be/) because of how common it is with them. Ignore the woman on the top of the page, motorcycle forums tend to be like that


bkfst_of_champinones

I heard it is especially bad on 2009 models and up, though I don’t know if that’s true or not.


wrugoin

Is there a method to properly recover or is a fall inevitable?


bkfst_of_champinones

Man there was just a huge discussion about this on a recent post. I could find the post but I don’t know how to link to a specific spot in a thread. Unless you want the short answer?


wrugoin

Just more of a curiosity. I don’t ride, but wondering if there’s a safety action to take once this starts.


bkfst_of_champinones

Okay. Yeah there’s a number of things that can cause it, related to road conditions or mechanical problems on the bike. High speeds make it more likely to happen, but it can happen at low speeds too. It can end in a nasty crash as you can see, but you can definitely ride it out, depending on how severe it is. It helps to keep a firm (hand) grip on the bars, but keep your arms mostly relaxed. If you touch the front brake, you will almost certainly go down. Everyone agrees on those parts. But there isn’t a clear consensus on what to do with the throttle. Some people (like me) say to let off the throttle all the way, gently if possible. Others say to increase throttle to decrease the weight on the front wheel. Some people say to brake lightly with the rear brake (I don’t agree with this one). So it probably is a case by case basis as to what’s best to do with the throttle. Best prophylaxis is to have a properly maintained motorcycle, ride responsibly, and wear a helmet and full gear. I think that was more info than you wanted but oh well lol.


wrugoin

Great, informative comment. Thank you.


bkfst_of_champinones

Awesome :)


PresumeSure

Tank slapper


_BewilderMe_

In the original YouTube video of this, the explanation was that the rear tire blew causing him to lose control.


ClickKlockTickTock

There's alot of things that could cause this, but speed seems to be a huge killer on bikes like this, especially when there's more weight on one side of the bike.

bonham101

Looks like he comes down from a wheelie hard. Right at the beginning


citit123

Speed wobbles, probably a newer rider, or the wind from the semi, a semi drove next to us, we were towing a trailer, and it went on 2 wheeles


DeadassBdeadassB

The cursed “speed wobbles” it happens when you go too fast, don’t really know the cause


MsJenX

In trying to figure out if he slid under the semi across the freeway. First we see him with the semi on the right then we see the semi on the left.


riverY90

Yeah, I think he did go under it without the wheels hitting him. The luck.

Yep. I live in a state where you can ride without a helmet. It sucks when its >90 degrees, but I wouldn't be caught dead on a bike without one. I'd rather be sweaty than get turned into a vegetable.

i’m pretty sure this is a prime example of that quote. obviously he obtained some injury of sorts but imagine how much worse it would be if he wasn’t fully dressed for it


thesteinlab

Oh yeah, all that gear would have really helped out if that 18 wheeler ran over him. I’ve been riding for almost ten years now and the amount of people that ride irresponsibly but think they are being safe because they are ATGATT is astounding. The majority of motorcycle accidents, including this one, are single vehicle ones (ie people taking corners too fast, trying to pop wheelies, etc.). While wearing all the gear is a good idea, it seems like the best advice one could give to a rider is to not outride their skill level.


adioking

What I’d do to see a dash cam video from another angle yikes!


Rooka942

That's some fast and furious shit right there


trollonte

Stuff like this, reminds me why I will never ride a motorcycle again... ever..


EasilyTurnedOn

Did you go around pulling wheelies on the highway like an idiot?


trollonte

No. Regular rider, part-time even. Still can’t control other drivers and the road flaws. All it takes is one tiny mistake and that could be it. Not worth it in my opinion.


TechnetiumAE

Everytime i see this reposted now its sped up more lol


RedBadgerLady

I think i would have sat and cried for a little bit


curvy_dreamer

Uhhh did he just go under that tanker?


mmburntcheez

That's a dry van trailer not a tanker


curvy_dreamer

But did he go Under it?


313802

Yes as the bike hit the ground


Glldinkiering

That was such a tiny amount of space, considering the truck had those guards that prevent decapitation.


curvy_dreamer

So he went behind it?


mmburntcheez

The guards are meant to keep small cars from running underneath the trailer as if one is stuck while the trailer is moving, the car may get dragged underneath the trailer tires and therefore flattening said doomed car.


Glldinkiering

No, they were created to reduce the fatality of passenger car/trailer truck accidents. The front hood of a car can fit under the trailer and the top of the vehicle is sheered off.


WeaponsHot

All wrong. Those are aerodynamics only. You can push them with your hand. They flex. It's to reduce drag. The won't stop anything larger than a pigeon from going through them. Source: 20 year trucker.


Glldinkiering

Weird, that was what my defensive driving instructor told us and said they were legally mandated on all new trailers after a certain year.


WeaponsHot

Mandated in CA as a fuel economy thing. They are NOT undercarriage protection.


sucksatgolf

That's the ICC bar at the rear of the trailer. It keeps cars from going under the trailer. Those are required by law. The side skirts are for better aerodynamics.


Glldinkiering

Thanks for clearing up my confusion! I must have remembered incorrectly.

Are those people fucking dumb? Because this is what happens when fucking dumb people have motorcycles.


VariantArray

I won't argue the 'dumb people' with motorcycles statement...I've seen plenty of them. This looks like he blew out his front tire. At that point, he's going down. The only thing he did 'wrong' was not trying to control that crash. But still, that happens in a second and you better realize what's going on real fast. ​ EDIT: Unless this was caused by him popping wheelies, then I wholeheartedly agree with you. Just fucking stupid.

My comment is made in the context of him popping wheelies, and going substantially faster than the flow of traffic.

I'm realising after my tenth watch that there's only a tiny space to slide under the truck, as it has what I assume is a storage area under the trailer

It’s not. It’s a thin sheet of metal or plastic there to enhance the aerodynamics of the trailer. I good kick could probably disfigure it.
