Paul, With either seat the top point of the pyramid of traction control is the seat/driver. The bottom is the tires contact points. The taller the pyramid is will increase the amount of vertical force upon the contact points when trying to change direction. A lay down seat set up would need narrower and shorter contact points in order to try and equal the vertical force that a sit up seat would have. At some point in width and length decreases it would not be able to produce as much vertical force upon the tires. Horizontal forces and dirt reduce grip .

I think I see exactly what your explaining.  I’m not disagreeing with any of it.  I’m going to try to include what you explained and bring it into my way of seeing its application.  I’m trying to look at thing by shaping the triangle to how I choose to use the tires.  … it’s tough to explain…  If my goal is to make sure I get enough grip out of the outside leg of the triangle to use it’s contact point to hold me in, then I’m mainly interested in the height of the triangle.  And I’m only concerned in how the height alters my ability to use the outside leg.  The inside leg will do what it will do when addressing the use of the outside leg.  All I expect and need to get out of the inside leg is minimal interference with the functioning outside leg.  When we need to use the other leg, it will then be acting the same as the outside leg does now.  We will just be shifting and dealing with it in reverse.  Simple cut and dry and I agree it works.

Does that sound ok?

All I’m suggesting is instead of looking at the inside leg as functioning to give us minimal interference with the operation of the outside leg, lets look at what else the minimal interference is maybe doing for us and enhance it.  I’m suggesting to look at the minimal interference of the inside leg of the triangle and having a function.  If your slowing down anyway isn’t the inside leg also helping to hold the back end in.  I’m suggesting to enhance the use of the inside leg while slowing down and cause the load to be split, as much as possible, between the two rear tires.  And then when you apply hp again, you can better control the introduction of the hp, because you previously have included being able to control slip at the inside leg.   It’s the outward direction of force you can use to give you more control over slip at the inside leg.

On a side note controlling slip at the inside rear is not all about gaining an additional tool to control slip.  It’s also about recognizing your also moving along the track while all this control is taking place.  Sometimes to fix a problem or gain a need, it’s simply a matter of preventing something from happening for an instant and your at a new place on the track where the problem no longer can occur.

I’d better stop for now and see what comes back.

Sometimes when things come back up it leaves a sour taste in your mouth. … :)   just more dry humor for my own benefit and fun
