What is the cause of “speed wobbles”?
4 min read
Asked by: Fredrick Edwards
Speed wobble is caused when something, either an inherent misalignment of the frame or components, or an outside force, that causes the wheels to track divergent paths. The frame flexes to allow this to occur until the action is overpowered by the self-correcting forces created by the bike’s steering geometry.
How do you fix speed wobble?
Quote from video: This is our normal response we grab that front brake you can gently use the rear brake to help scrub off some speed.
Are speed wobbles common?
It’s not very likely that your motorcycle would get a speed wobble at low speeds. In fact, this typically only happens when your bike is traveling at very high rates of speed. If you are riding at high speed and your motorcycle gets a speed wobble, this could be extremely dangerous.
How do I stop my bike speed wobble?
Quote from video: You've got a low seat pin sticking out maybe a load of headsets pages here and even an upward turning stem you can have more flex. And more chance of speed wobble.
Why do death wobbles happen?
What Causes the Death Wobble? In most cases, the death wobble will occur when driving at speeds of at least 45 miles per hour and can be triggered by hitting a bump or pothole. Some of the most common causes of the death wobble include poorly installed suspension parts or loose or damaged steering components.
At what speed do you get speed wobble?
between 25 and 35 miles per hour
The bicycle speed wobble — some call it a shimmy — only happens when you’re going very fast downhill. It usually starts somewhere between 25 and 35 miles per hour, and it’s exactly what it sounds like: Your bike begins to wobble aggressively side to side, seemingly for no reason.
How do you recover from death wobble?
Front end speed wobble recovery:
- Keep a firm grip on the handlebars.
- Roll off the the throttle with control (no sudden moves)
- Lean forward into the handlebars or pull the handlebars to you. …
- Allow the motorcycle to decelerate naturally without downshifting or applying the brake.

Can Unbalanced tires cause death wobble?
GET YOUR TIRE BALANCED:

Can wind cause speed wobble?
In bikes, speed wobble starts when something causes the front wheel to accelerate to one side. This could be something as simple as the rider shivering on a cold descent, the rider sneezing, a gust of wind, a bump in the road, or perhaps even a wheel that’s not quite true.
Why do motorcycles wobble at high speed?
Aerodynamics: while traveling at higher speeds or into a headwind, the motorcycle can experience aerodynamic lift, lightening the forces through the suspension and contact patch, changing the effective trail of the steering, which allows the motorcycle handling to become unstable and shimmy.
At what speed does tank slap happen?
