That was painful to watch. There's a comment that states the person who filmed it says that bike had been doing that for 5+ miles. If that is the case, the rider was an idiot. It doesn't matter what he was wearing or what he was riding, but great to see that's all the narrow minded judgemental stupid people go on about.

Sure. Let's encourage the ignorance to persist.

Most riders are not ignorant to the benefits of protective gear and assume the risk. Most likely the state he is in requires helmets and that is the only reason he had one on while not wearing anything else. His bad choice was not pulling off if his bike was having issues.

Just came from RI where 80% of the riders are not only dressed like this guy but go the extra mile of stupid and ride without helmet.

As for the wobble...
All it takes is a worn out front tire for that to happen on any motorcycle. It can also be cause by steering bearings or whatever.
When it occurs...relax and don't fight it. It will eventually stop. Casual cruiser riders seem to spend more times on "accessories" than they do on tires and suspension upkeep so I'm not surprised. Instead of telling people he panic'd and death gripped a speed wobble until he used his face as a brake, he'll probably tell people "He had to lay it down." or some BS like that.

Seems similar to getting wheel vibration when a rim is out of round. You only feel it at highway speeds. Except it's still balanced since it's on 4 wheels.

**A little cursing at the end**

It's only an 18 second clip. It guys motorcycle starts wobbling side to side. I'm surprised that he didn't slow down. I guess he thought that he could regain control.

At first, it doesn't look that bad but then I noticed that he's wearing a shirt with cutoff sleeves. He's going to have road burn for sure.

Acceleration is more likely to help in a tank-slapper.

LOL

Fat and stupid decides to one hand a bike prone to speed wobble.
Tank-slappers can happen on almost any bike. The stability typically comes from gyroscopic forces and your handlebar inputs barely factor over 15MPH. Most motorcyclists don't even realize that they are pushing the right bar forward to initiate a lean that turns right (the lean is proportional to the force). The wheel points left, not right, but even that is almost imperceptible. Riders learn this and apply it subconsciously. You point the tire like a bicycle only at parking lot speeds.

Not a motorcycle rider, why does riding with one hand cause the bike to wobble like that and when he did grab the handlebar with his other hand the wobble wasn't all that bad, why couldn't he recover?
Definitely wasn't the cause. There are a ton of factors that can cascade into a tank slapped including the pavement, speed, tread, tire type, suspension, damping, etc. Unpredictable and can happen on almost any bike. It's a huge reason why you need to were full gear regardless of your skill/safety on a motorcycle.

Shouldn't be riding one handed like a bellend.
Literally had nothing to do with it.

Most proper motorcycles are supremely stable in that kind of situation (smooth, dry, level road, straight riding), there must have been something wrong with the bike. Though if he was still one-handing it after multiple bouts of speed wobble, he's a knob and he at least partially earned that harsh lesson.
WAY too many factors can lead to it even in those condition many of which have nothing to do with the condition of the bike. About the only thing a second hand would have done was dampen steering enough to change the conditions where this might happen as a slightly different speed or something.

its the POS bike the guy was riding. I ride one handed all the time on the interstate. My BMW has Cruise control and its nice to give one arm a break for a bit. also the road may have been scored with wavy lines and his bike got caught up in the scoring.
Just be aware that it can happen on your BMW too, even when the bike is working perfectly.

Most riders are not ignorant to the benefits of protective gear and assume the risk. Most likely the state he is in requires helmets and that is the only reason he had one on while not wearing anything else. His bad choice was not pulling off if his bike was having issues.

Tank slippers are often unpredictable. Just because this one telegraphed itself doesn't mean his only mistake was not wearing gear. What if he didn't recover from the very first one? He couldn't possibly have known that he would and could pull over to justify his lack of gear. Tank slappers happen on just about every model. The conditions change and are impossible to predict.

My understanding is that it had been doing it for 5+ miles..

Yes. That's why I said it "telegraphed" itself. Doing it for 5 miles isn't what helped him pull out of the first one. Unless they all telegraph themselves and there are no other threats that are potentially out of the rider's control, it doesn't make opting out of gear any less stupid.

My point was aimed more at the report that he had just previously recovered from several wobbles and just kept going rather than slowing down and keeping his hands on the bars.

When I was a kid riding dirt bikes I would just wheelie out of any front end weirdness.

I can't imagine one of these tards on their big ol' hog pulling that off.
