Countersteering Confession

[Motig]

I've been plucking up the courage to say this for a while so here goes. Countersteering is all Bullshit, its a myth perpertrated by people who have nothing better to do in their spare time. There is no way Ive ever used it in my years of bike riding so there!!!!







So I went for a ride the other day.................and I do

So you're obeying the laws of Physics as well!

It's amazing the numbers who aren't affected by those laws.

... ride with just your throttle hand on the bars & start weaving (in & out of imaginary cones) as you ride down the road ... it should all be clear as mud then ...

You may not believe it, but its an established physical principle coming from the gyroscope effect.
I would go into it further, but it'll need someone smarter than me to explain exactly why it happens.
A diagram would help, but I'm at work at the mo so I ain't got no time.

Re-read his post, he does believe in it!

Yup just another admitting he has been doing all along just not realised.

#1. Countersteering is not a religion.

Go to your pushbike, take the front wheel off, spin it up and try and turn it.

See, the result is 90 degrees from the input.

Now, put the wheel back on your push bike, because you will need it when you bin your motorbike.

If countersteering doesn't work, then helicopters can't fly either.

I am learning to ride and I find it so hard cause yeah it is very confusing and it is totally different from my car, but I have a great teacher ( ) and it is going pretty well

They don't.. Helicopters are simply a machine thats trying to crash, and its only the faith of the pilot that keeps them in the air.

Well, I heard it was the fact that they are so ugly that the earth repels them.

However they fly, it is a welcome sound when it is your last chance out of where ever you are.

Its called Gyroscopic precession and in laymans terms it means that if you exert any sideways force on a spinning wheel, the result will be felt 90 degrees in or with the direction of rotation.
Imagine the front wheel of a bike and you are looking at it down the forks from above. Travelling along the road the top is spinning away from you. You push on the right handlebar (or pull on the left one) which is going to try to turn the wheel to the left. In effect you are exerting a force on the rear of the wheel from the left side (or the front of the wheel from the right, though its easier to visualise it on the rear). Following the above principle, any force exerted on the left rear of the spinning wheel will take effect or be felt (after 90 deg) at the left top of the wheel. This will have the tendency to roll the bike right. This is how we lean the bike using countersteer. Then it is all up to the shape or profile of our tyres to provide the turning force.

As a side issue, I often think about that poor tyre relative to the road. The axle (centre of the wheel) is travelling at the speed of the bike. The top of the tyre has to be advancing at twice the bikes speed and the bottom of the tyre (the bit touching the road) is doing 0 (Zero) speed (assuming no wheel spin). A few numbers to get the mind going on tyre forces. A sprot bike doing 300 kays requires its tyres to accelerate from "0" Kays to 600 Kays than back to "0" Kays in one revolution..!
I might be talking shit, but thats the way I see it and the physicists out there will no doubt shoot me down In flames.

The control force on a Helicopters spinning disk is exerted or activated 90 degrees before it is meant to take effect. This tilts the disk in the appropriate direction.

You of little imagination......

A hot air balloon/or helium could of ascended the person out and then just hook that up to the F150 on a long rope and tow back to the morgue.


Or theres the more exciting way of attaching yourself via a cord to a balloon letting that go nice and high and having this fly by
