So if your rear wheel is off the ground your ass should be off the seat until the rear wheel settles back down?
I should of posted this on the Flexy post of homeslice/Kenny, but depends whether jump is done in line like elite racers or side ways like hayseeds and how hi the bike jumped for the bang down whether you want to take it in or out of saddle planting. Ya don't have to do much nor can ya do much if launched like these IOM leapers in straight-ish leaps but try to get bike to land evenly as possible and keep head away form bars for the slam down. Best to have rear touch first though.
No one can do turns like me on tri-linked Ms Peel so its impossible to convey even with accurate description, its unbelievable. The leaps I talk about to let modern bikes settle before landing are done by sideways hi side leaps and you definitely better not be out of locked in center of saddle at any point during that maneuver of you will never get butt back in saddle before crashed. You can't do this type phase 4 turn w/o going in harsher faster than racers do in crash video as must go in so harsh you will crash trying to keep bike even in a toe hole of contact.
I crashed a Ninja @ ~120 mph ie: 14000 rpm in 3rd to 4th shift because it stood on rear tire and wobbled bike right out from under to low side then hi side landing on my head with bike on top. I detest unintended wheelies.
You work up to this on moderns till the bike is tank slapping juddering like seen in race video turns, then that tells ya how much faster to go in to let it-make it low side into a tank slap for the hi side save air borne long and far enough the chassis has settled down to take the landing predictably control ably. Its about sharpest way to turn but not always fastest way as harsh acceleration hesitates while air borne. Its just a way not to ever need brakes or loosing momentum in switch back chicances so can accelerate though them more like seires of short WOT upright sprints. All turning in phase 4 is done with bike off surface after the initial throw down/trip out by power and straight steering, as seen in crash of Stone movie.
On Peel I got sense of how much power for the speed and traction/temps to pull this off by snicking gear and throttle UP <where ya see all the rest hard on brake lights>, then I tip her a bit to feel her suddenly trip down by tire spin, then give more power upright and do the turn by series of little tip trips down skips till rear drifts out a bit to hook a jerk back up right for more power increase to be able to trip out the next short straight in decreasing radius turns. All turns become fast decreasing radius done this way. Allows finishing turn and a shift up out of there before normal bikes/riders have even made it to apex max tip over.
Realize it takes more than normal Combat power to do this up to 80-90 mph and it better not wheelie while pulling more forward G's than stands the moderns up on end. I don't think traction and wheelie digital control will allow moderns to do this nor balloon tires on edge enough traction and control to punch through phase two w/o oh oh's.
