Position in seat?

**bogan** · 9th April 2010, 19:05

I was serious, whips being a technique used to jump a motorcycle very flat and turn sideways to the direction of travel in the air, not whips as in the S&M tool, i do not want to know p.dath's or r soles experience in those areas

Has p.dath been out p.dath'd??

This is the funniest thread I've ever read on KB. I don't think I've ever handed out so much green bling, and deservedly so. Pure gold.

Next corner, I'm just going to freeze.

Hi, I'm new here to KB. Trying to find my way around.

Don't make any sudden movements and just walk backwards veeeeery slowly.

Welcome to KB

The forum for discussing the physics of motorcycle riding and whether or not to wave at other riders

Oh, and don't forget to mention nazis

Quite possibly.

What a very entertaining and informative read.

And welcome, cb400, to the wonderful world that is kb.

edit, oh and if you or p.dath want to write a wiki on 'whips' I would be greatly interested! some crazy forces going on in those.

Oh OK - that makes a lot of sense too. That'd be the main reason for leaning outwards I guess, as well as letting it break traction quicker. Then again, you probably would want it to hold traction as long as possible right? And not force tractin breakaway too soon. And only once it breaks traction would you revert to realignement of the bike to create an alternate inward force? Is that right?

I know the motard guys break traction on purpose, but I see that sport as being more like drifting, where its not so much about speed as it is about style. Am I right on this?

I have no idea what a "whip" is (at least in the context of MX). I am guessing it is moving the back wheel out of alignment in the air while jumping? While I have never done one, I could try and figure it out on engineering first principles. If its in the air, it would probably relate to the principle of conservation of angular momentum.

And PS Hi cb400 - this place is addictive and you can pick oup lots of tips.

Like I learnt yesterday (too late)- dont polish your tank.

**R-Soul** · 10th April 2010, 11:50

edit- double post. Mine dissapeared?

a lot of mx stuff it riding ruts anyway, so breaking traction rules etc dont really apply as you're thinking.

I watched the motards at bots and the only regular loss of traction was some braking stutter, so yeh, probly the stuff you saw was drifting for style rather than speed.

this is a whip

think it involves more than first principals

Hell thats awesome!!

Everything works on first principles in applied maths - but your video seems like a layering of many effects, all based on the first principle of conservation of angular momentum. On my observatin many things could be causing the overall look.

The effects could be:
- forces caused by moving gyorcopic effects ( by moving the handlebars and hence the spinning front wheel) and their associated rules
- the way that he leaves the jump (already moving to the side and not stationary) so that he can change the momentum back in mid air to cause some other pat of the bike to move in an opposite rotational angular direction to compensate, and
- changing speed of rotation of the wheels by braking or accelerating, causing the bike tp angle up or down.
-optical illusions from him leaving the ramp at an angle that is not expected (which allows him to be more misaligned from the start).

But I reckon his trick looks so good ecause he combines all of these effects...
AWESOME!

So after all that did we get a consensus on if the OP needs to move his seating position or not?
After all that was the question you guys were answering right.

How come you have the same avatar as Squiggles?
