Countersteering

[GSVR]

It's what happens when people don't use the search function.

What search function that just took me to one of Frostys ramblings?

Hey, there's some good shit in that thread; look for my posts!

In that case I think you fall on your arse

And your wrist & your ankle & your shoulder & your arm, Breaking most of them.

You'll hear other riders going on about countersteering and what it does.
Dunno about you lot but egghead types going on about gyro this or that gives me a headache.
Do ya really want to know what countersteerings all about?
Find a long straight quiet bit of road.
Ride up and down it slowly to make sure its clear of hazards.
Now staying towards the middle ride up the road at 50km/h. Pull back on the left bar and push on the right bar gently. -so you are turning the front wheel to the LEFT
Now do the same again this time pull the right bar and push the left. so turning the wheel to the right
Which direction did the bike turn?
Congratulations you now know about countersteering -easy innnit ?

Yeah its easy alright but what about counter-countersteering. We've all done it probably most of us without even thinking about it. But should it really be refered to as steering?

Let me explain. You go into a corner at speed thinking its going to be alot tighter than it is or theres something in the way or maybe your just procrastinating or indecisive. So your've countersteered way to much and have to counter-countersteer to correct this. If you screw this manovure up you may even have to counter-counter-countersteer to correct or face information overload and countersteer off the road.

So your've countersteered... counter-countersteer... counter-counter-countersteer... countersteer off the road.

Gosh, all those counters, you'd almost want a counter counter to keep track of them...

The real top riders like Rossi can countersteer up to so many levels mere mortals can only dream about. Like a supercomputer doing millions of counterstreering calculations a second.

With all this talk about gyroscopes I'm reminded of my introduction to motorcycling .... I was assured that bikes were immeasurably safer than cars due to the two enormous safety features built into them - gyroscopes - that would ensure they remained upright "no matter what". I couldn't find these highly technical safety features no matter how hard I looked, let alone figure out how they worked ....... yes I was blonde as a child.

The gyroscope thing is all crap. The lighter your wheels are the better a bike is to steer. Gyroscopic effects are counterproductive to riding.

Top racebikes don't have carbon fibre rims fitted because they look good. As well as the lightness making the bike turn better they accellerate and brake better with less moving mass.

So i assume from that, that you have never ridden a 16 inch front wheel GSX1135EFE in anger then.

Are you inferring that a 16" front wheel generates less or more gyroscopic effects than a 16.5" or 17" or 21" front wheel does?

What about that huge crankshaft your making very angry by reving the shit out of. Maybe that doesn't want to move from its gyro axis. Those big old bikes did some funny things at high speed on sweeping corners and even straight bits of road..

Im inferring that the front end of those fuckers had a mind of their own, Ask Scrivy.
I followed him for many hard out kays, him on an EFE & me on a 19inch wheel Katana 1100, he was a one man freakshow, not that it ever slowed him down.

If gyroscopic forces are crap how do explain how a "race bike" or any bike for that matter can lift the front wheel exiting a corner yet still hold it's line? It's not just the mass of a spinning object it's the speed it's spinning at. Less mass just means less effort is needed to change direction. Try holding a bicycle wheel by the axle and give it a spin, quite a force is needed to tip or lean the wheel over left or right.

Think of it this way, certrifugal precession means the input takes effect 90 degrees later in the direction of the spin. So, if you turn the handle bars right you are trying to move the back of the wheel to the left , the result 90 degrees later is the top of the wheel moves or leans left draging the rest of the bike with it.. easy!

I don't wanna get into some long dragged out discussion on your beliefs on what holds your bike up. Whatever you say is ok by me. Just dont fall over.

So why did Yamaha reverse the rotation of the crankshaft on their MotoGP bike a few seasons ago? Reason I'm asking is because I truely don't know and you sound like you would know the answer.
