that is a VERY specific condition of oversteer that is quite rare. usuallly, the rears are spinning and have lost their slip angle ...more throttle (faster wheel spin) decreases traction . this can be seen by attemping a 180 degree maneuver.... brakes or increased throttle will often increase the rate of rotation.. if you can time both feed in , for a oversteer condition, and dont have abs as to lock the front wheels, you can sometimes stop the rotation. But, again, this is specific condition......advising this for any oversteer condition is quite dangerous. a normal power on oversteer condition can be controled by matching steering inputs opposite to the rear end, with /or reduced throttle.

not really.......... but close..... in car talk, it then transfers to the over-steer that is over corrected and continues in the opposite direction, and then continues the cycle until it ends up in a full spin generally.
its not the handle bars "breaking loose" its the entire instability of the motorcycle , front and rear, out of sync. it's very analogous to pilot induced oscillation (plane bouncing up and down on a landing approach).

Good thing he had both hands on the wheel, unlike in the prior banking.

If you are talking about this, it is a very specific type of save.. basically both feet in, and wait it out.. the dynamics is that the front that would normally allow for the rear to come around, gets locked up and washes out forward, taking the rear momentum component out of equation. many times this helps (both feet in at a point of not being able to save through correction) from completing a spin . the best way is to have the steering input keep from getting to that point by matching the rear of the car's movement.

Here's a little drift I did through turn seven at Sears Point. Completely unintentional but by that point in the event the Hoosiers were overheating. It was in excess of 120 degrees that day. It's all about practice on the skid pad and applying that knowledge in safe corners.

In this context, I am definitely going for oversteer....

Topical thread. We're taking a bunch of guys ice racing this friday

If you don't have ice or snow covered back roads (with runoff) then +993 for rally school.

That was a perfect catch and correction. of course, it was driver induced to start overheated tires or not.. ......and we have all been there. But the correction was perfectly caught and the release was timed well too as there was no oscillation.

Thank you both for the suggestions!

This was amazing. Why did he straighten the wheels during the slide.
He knew that if he kept it opposite locked, the car would pendulum the other way?

mark kibort

actually, at that point, when locked , there is not much the wheels being angled can or will do. however, feeling the reduction of front grip being locked, allows the rear end to catch up , straightening the wheels before the chassis is pointed straight, allows for an instant recovery (by brake release) when the car ends up being pointed straight..... (easier than timing it) however, if the front wheels were rolling, this would be a different set of conditions.

I thought I was just good at driving - going to let me wife know I'm good at sex as well!

View some old videos of the Ayrton Senna's racing in the rain. At the speed he was going, he absolutely drove his car to the limit....and his car control of recovery is miles ahead of everybody during that era.
