[edit] Single pivot point
I wonder if speed wobbles would apply to any vehicle with single front pivot point. Reflex Action (Apr 2005)
[edit] Speed Wobble
We can have articles link here, but lets not pretend that "Speed wobble" is a popularly used term (unless it is?) AdamBiswanger1 03:32, 14 July 2006 (UTC)
[edit] Speed wobble in cars?
The article says: It can occur with motorcycles, skateboards, bicycles or in theory any vehicle with a single steering pivot point and a sufficient amount of freedom of the steered wheel; this does not include automobiles..
Googling for 'shimmy death-wobble' will produce plenty of webpages describing similar things in cars. Also the article Hunting (engineering) mentions this. So why this remark? -- Han-Kwang 11:08, 15 July 2006 (UTC)
- Nutation requires 2 degrees of freedom orthogonal to the spin axis. Car wheels do not have this freedom. Jurien 01:07, 17 July 2006 (UTC)
[edit] Death wobble vs. shimmy?
It's not clear from the article what the difference is between a death wobble and a shimmy. Han-Kwang 11:08, 15 July 2006 (UTC)
- Thanks for the feedback, I'll make it clearer. Jurien 01:07, 17 July 2006 (UTC)
- When I wrote my comment I didn't realize that you were in the middle of a rewrite. I saw today after you bolded various phrases that it was already there, just not under the heading Shimmy and death wobble where I expected it. I'm not confident to change the article without introducing errors, but I suggest that you start the section Shimmy and death wobble by explaining in simple language what the difference between the two is, preferably without technical terms such as gimbal, nutation, and pivot. After that you can go into more detail. I must say though that I find it hard to follow the article despite a PhD degree in (chemical) physics. A simple picture of the two cases would help tremendously, for example with a front view of the bike and a top view, with in two different colors the different extreme orientations of the bike plus its rider.

- Good idea. This wiki entry is very much under development.--Jurien 04:35, 18 July 2006 (UTC)

[edit] An Inaccuracy.
In the article, you write, "In 2002 Harley-Davidson was sued in a class action suit for injuries associated with high speed wobbles, also known as "tank slappers" because of the tendency of handle bars to move towards the tank." Are you sure? Because I am pretty sure that is not true. If you do not have facts to back that up, I would remove that statement from the article.
- I'll put a [citation needed] on it AdamBiswanger1 14:56, 10 August 2006 (UTC)
Since there has been no citation added and it has been over a week, can I rightfully remove that sentence from the article?
