This is the crash analysis forum. Here's my analysis. You were going too fast for conditions and skill. Slow down until you have more skill. You can also do what others have posted. You can learn on a smaller bike with less horsepower.
I think a better choice of street tires most likely would have forgiven your throttle mistake.
Either your tires are completely whacko, or you gave it far too much throttle.
How old are your tires? How worn are they? No one is out there selling new tires that highside coming out of parking lots as normal operation.
i dont think i was on/off the throttle. my instint is to either keep it on or let it off.
Archimedes: not much of an angle. It was a typical exit. I wasnt trying to impress anyone. The bike has is well modded with power commander III. I've never had this issue with Pilot Powers.

Well.. thats what I was talking about. You just asked the same question about what I think made you crash.. That you said you didn't do..
Your supposed to give it gas.
If your tire is spinning and your leaned over and you slow the tire down by braking or letting off the throttle.. it's going to snap the bike into the position of attention..
Command attention from your bike.. Give it gas. Let that tire spin and lean into the turn.. look into the turn.. step on the pegs.. don't let it mount you and start humping like a horny dog.
I think your being too timid.
I highsided a bike entering the hot pits at thunderhill doing the same thing.
True story, I decided to ride my 05 ZX-10R to work this past December. I live 65 miles from my work so I needed to fill up in order to make the round trip. At 6:30am I pulled into the Joe's Travel Plaza to fill up. This is also a Truck stop with a fueling station for big rigs hence there are two driveways exiting the Gas Station. As I was leaving the gas station drive way making a left there was a Semi making a left out of the other driveway to my south. I made the decision that I wanted to get in front of the Semi so I was not stuck behind the big truck on the slow drive down the access road to the freeway. I gave it some throttle to which it spun the rear tire and stepped out to the right. I did not crash, but it caught my attention. Does the ZX-10 always spin the tire at 1/3 throttle... no. Did it spin the tire that morning because it was cold out side, the road was cold and the tires were cold... no it spun the tire because I did not account for the cold air, cold road and cold tires yet I made the choice to attempt to get in front of the truck.
I was able to react and compensate for my poor choice at that moment and continue on in to work. That said I know what caused the problem...me. If you truly want to analyze your crash figure out what you did to contribute to it. A failure to account for conditions and adjust/modify your behavior accordingly is on you not the conditions.
