The answer is still yes.
I thought you said as soon as you hit horizontal your bike would steer into the ground.
I actually asked my physics professor about it and he started cracking up. After about a half hour of diagrams and explanations and ponders by both him and myself, we came to the conclusion that under perfect conditions with CRAZY sticky tired and sticky asphalt, it could work. I say we have Rob try it...
Ok, forget what I posted...I just realized that your original question was regarding going below horizontal at a track, in a turn.
No. It would steer you into the ground/inside of the turn.

In a banked turn going below horizontal. And Dr. Pravica at UNLV said it's possible!

I do not think it is possible in a turn does not cause the bike to decrease it's elevation...regardless of the banking.
I didnt think I could fit my fist in my mouth, but let me tell you...
You fit lots of things in your mouth, don't you?

The laws of physics will momentarily allow this based on centripetal force. Based on the picture shown, it would only momentarily be possible.
I'ma go with the guy with the phD in physics on this one... just sayin

Please have him explain how you will not slam to the ground once you cross over the horizontal plane, while at the same time not reducing your elevation in order to compensate for the bike wanting to push itself to the ground.
Im curious, completely ok if I am wrong, and interested in knowing how it would be possible.

Warning: Contains math
Assuming that your speed is great enough there's going to be a torque pulling the tires up along the plane of the incline, basically trying to flip you over. If your tires are good enough, and the road is clean and traction-y enough they would be able to provide a counter-force to overcome this torque. But a by-product of this force, since it's on an incline, is a force going in the y-direct (up). So as long as the sin(frictional-force) is greater than mgh you'd be perfectly fine for however long of a turn. And if it's slightly less than mgh, as long as the turn was relatively short, you'd be fine, just not for a super-sustained amount of time. Of course this is all with large speeds... so I think Rob should try it.

Corrected for the actual horizon line..... still very cool but less dramatic.
