this is kinda what im thinking.
i also listened to someone real fast running same tires/ and dropped my tire pressures that day.
Running 20psi rear 25 in the front, and i really think that contributed to it, shoulda left it at 30-31 front.
tires were a gpa slick in the rear and a gpa kr449 in the front, brand new front and 2 TD on the rear
I'm not surprised your front folded.. That's pretty effing low dude.

My 2 cents. Back down the speed a little is my suggestion. Figure out what when wrong, then work back up to pace.
This. This is what my goal was this season after a couple crashes last year, and I've become a lot faster and more comfortable because of it.
28 cold in the front shooting for 31-32 hot psi is usually the goal. 25 cold is a little low but should only make the bike unsettled and lethargic on direction changes. I wouldn't put it on low tire pressure for that spill.
I saw you do it a few other times at different turns. You let off the gas mid turn. This is of course a no no. In this video I see that you let off the gas a little bit and then more lean angle was added. Then as quick as you can say shit, the bike finished the job for you. But as far as I can tell you let off the gas just before you tipped in a little more. That is the quick way to make a front tire mad. The low tire pressure may have exacerbated the the potential, but it was the throttle input that was the nail in the coffin.
I'm no expert, but what I saw was that you were on and off the throttle mid corners fairly often (especially on the longer corners) and on this particular one you rolled off (loading the front end) then decide to add lean angle and throttle at the same time. Because I had/have a habit of that myself, I tend to pay a fair bit of attention to the whole "don't add lean angle and throttle" bit.
On the quicker corners you're okay, coming up to the slow part of the corner then taking away lean angle as you're applying the throttle, but on the longer "patience" corners you seem to toss that out the window.
If you're crashing what you consider frequently, then you're doing something wrong and you need to figure out what it is and slow down till you correct it.
Tire pressures probably didn't help you any, and running them that far off may make a tire give out when modern rubber technology could have otherwise saved you from yourself.
Am I the only rider who successfully lets on and off the gas during a turn?
I am saying this jokingly, cause when you read this thread it reads as if it's the end all, be all of moves that guarantees a crash. When at Jennings, I started to even get comfortable braking mid turn to tighten up my apex to T11. Getting off the gas shouldn't wipe the front end out at an advanced pace when the lean angle isn't maxed out, etc.

I did not read everyone's post, this one caught my eye and I felt I Had to reply, your pressure was WAY too low, and at the pace you were riding, it would have been hard to keep heat in that tire. So no matter what this was the issue, it is the first thing I came to when I watched the video, the front tire never tucked, it folded in on its self.

I hate that pinching feeling. And it ain't easy to pinch a GPA either!! The UK ones are a whole different story though. The carcass is way softer. It almost looks like a V cup too vs the shit we had to run at AMA this season..

Could you explain the difference between those two things? They sound like the same thing to me.

^ this.
im not a new rider.. the corner worker that witnessed it posted on the local forums here too, i was not at max lean angle, even though the cam looks pretty low.
second, there is a big difference between completely rolling off throttle, and easing off a bit to avoid bumps/seams/going wide. i do it all the time when my suspension gets really upset going over some of the transitions on our tracks.
im just glad i learned something and the bike is barely hurt.
just waiting for next season now, dont think ill get any seat time this year.
Thanks for the replies guys , im gonna blame it on the rider and live with it.
