Valentino Rossi bemoans new Bridgestone tyre direction

Valentino Rossi says he is mystified why a new range of Bridgestone rear tyres will be introduced for the 2014 MotoGP world championship. The Italian spent the majority of the opening day of the second test in Sepang working on the set-up of his factory Yamaha YZR-M1 to work with the new generation Bridgestone tyres. A stiffer construction to help with temperature...

Oh boy

You're welcome to elaborate and bring your technical input, i'm always willing to learn new things.

Funniest thing I've read yet Gasbag - by the way, thanks for allowing others to express their opinion

Again "countersteering" is a miss used of the words, it does help lean the bike not get it sideways in any way.

I believe I already said that

Counter steering is in effect on any two wheeld transport, even on a moped turning into a corner at 10mph, even on a bicycle - it has nothing to do with rear wheel sliding.

Of course the absolute brilliance of Quasimoto's

rear brake / engine braking focused riding technique is not only can you do away with clutch and front brake levers, not to mention handlebars, but it works with any Yamaha! Because every single Yamaha ever built  contains inherent Kenny Roberts Snr DNA meaning regardless of weight distribution, rake, trail, wheelbase length, weight, two or four stroke, twin shocker, cantilever or rising rate they will all behave in exactly the same manner. XS1100, TZ125, no matter  - exactly the same handling mannerisms. Brilliant! Makes you wonder why the GP team bothers to tweak the chassis at all.

Really?

In that case why trying to "correct" my reply to someone else?

When it becomes too obvious you don't even READ people replies before flaming them and then get your wires all crossed, suddenly you "already said so".
The point is, no one get a bike sideways by "counter steering" only and as it is used today, its only effect is to lean the bike over.
Hence my comments on the effects of the slightest lean angle throwing the rear out related to the rear wheel already sliding. What does your "countersteering" BS have to do with that?
As for the correct technical words for this it would be opposite steering not countering.

The term used for what you call 'opposite steering' is opposite lock - something else I said earlier.

You're an overbearing idiot who spouts so much drivel you forget your earlier arguments. Look back through some of that drivel and I'm sure you'll find where you said you use the rear brake to counter steer into corners.

Opposite lock?

 Meaning; you get the opposite steering to the lock. Nope.

There is NO steering the rear wheel needed to do what people call "countersteering" so there is technically nothing to counter, point i alreay made, you can go with both wheels spinning at the same speed into the turn, you have nothing to counter.

What you do technically is to oppose the steering angle to the direction you want to turn into to lean the bike.

My Oxford: Second Edition 1975. Counter: Opposed, opposite, in the opposite direction. Mechanically it is an opposition of action.

If you reffer to this in relation to countering the action of the rear wheel going out of allignement, it would be counter steering,  which is also used in cars, when it comes to leaning the bile the opposite way to where you want it to turn it would be opposite steering to be mechanically correct.

People might well want to use the word for both, it is obviously not the same thing.

And some little detail Xtra: I wish you good luck staying on top of your bike when you "countersteer" and are already at the limit of your front tyre adherence on the brakes, which was my point in the first place.

Hang on

 One of the greatest tools a motorcycle rider can possess is the operational technique of push steering! Also referred to as counter-steering, positive steering, or gyroscopic steering.Push steering interrupts inertia (forward moving power) a result created by riding a ‘single track’ / tandem vehicle – motorcycle – unlike the double track/four wheels a car has. It involves the physics of gyroscopic inertia.

You and the motorcycle must first be leaned in the direction of the turn, and steering briefly in the opposite direction causes that lean.
Ok I did copy this from teach your wife to ride a motorcycle.

 Very basic isn't it? So why are guys still not getting it?  Brought back in its context this exchange was quiet funny, i was replying to a post, just mentioning the fact that rear wheels already sliding, "the slightest lean angle would throw the rear out" (on how i was doing it as opposed to some other guys).

How i did lean the bike is yet another story, something else, i also use the pegs.

You're OK DeGrasse

I'm quite happy to ignore the crap (except when it fills the thread like the backup from an overflowing toilet) and add the occasional comment/opinion based upon information I hear from colleagues, associates or journalist here in Italy.

But you go on Son... seems like you're having a whale of a time and making lots of new play friends!!
