What is it with me and Left turns

I cant figure out how I lowsided today. Went into a pretty slow left hand constant radius. Went in at a good speed,(maybe 40) had a good line. I was maintaining the throttle thru the apex. When my knee touched. It seemed like it just kept going down. I couldnt stop it.....The next thing I knew I was on my left shoulder looking at the world going by....Then I went in the ditch back first. By maintaining the throttle you shouldnt loose the front of the bike. I never thought I was giving it too much too the rear. I am riding a GSXR 600 with GP 208s that were hot. I had been riding hard for an hour or so. I am a pretty seasoned rider but it seems both times I have been down the case was the same. Except last time was on 208ZRs. I cant tell if I lost the front or the back. It happened FAST.........and yes it hurt!!!!!!
someone school me.....
New riders read.......................... This was also a good example of the difference between wearing protective equipment and not. Had I been in jeans and a t-shirt I would be unable to type this tonight. Was wearing full good quality suit, gloves. My boots are a little on the cheap side(I managed to jam my big toe on my right foot) I was also wearing a good quality helmet.
I didnt get a bit of rash nowhere just a little sore...

Something on the road, or that turn was just a bit more slippery than the turns before?
The key may be that you went into the turn with too much speed. It's safer for a number of reasons to enter a bit slow, and accelerate through-even for a constant-radius turn.

It is likely that you washed the front tire.
Buddy of mine tossed his bike right in front of me a couple of weeks ago at the track. He thought he tossed it from lifting the rear end dragging hard parts but I saw what happened: his front tire washed out on him and he did some asphalt surfing.

its safe to say everyone will lowside at least once while riding a motorcycle. i dont know what caused you to do it. but im glad you were wearing your gear. it is the difference between a trip to the er to get scrubbed out and just dusting yourself off and picking your bike up (unless its a really bad crash, which in case the gear will still minimalize the damages greatly)

I went back up the site where I crashed. It looks like I spun the rear tire mid curve. And it just came out from under me. Maybe too many trips up the hill on the 208GPs. I was looking at some video from the previous week I made with the camera on the rear of my bike facing backward. I did't realize I was spinning that much out of the turns.
Thanks for your concern. I pretty much got up smiling. The thing that aggravated me the most is I had to ride home with dirt and grass all down my back. Very Impressed with my Hein Gerrick Jacket I bought last season. It seemed to do well to protect my shoulder that I landed on. But the Jacket had minimal damage to it, considering I had a pretty hard landing (hard enough to crack my helmet)and slid 60 ft on the asphalt.

I'd agree with Trev. Your time through a short tight radius turn will make almost no difference to your overall pace, so best to enter slow and roll on the whole way. The other thing though, is it possible that turn had some camber away from you? i.e. if it had cambered your effective lean angle might be more than you think. camber can be a subtle thing to perceive but can make a huge difference. take a look at that corner again.

Come to think of it, the turn is cambered away. But just slightly. Could be what did it. I think I will also take Trevs advice of entering more slowly. I do think I rolled on too much. Yes the tires were matched...I guess, I purchased and mounted them at the same time...Dunlop 208GPs Medium compound front and rear. As far as the bike goes. I got lucky. It wend down right onto the sliders on the left side.. All it broke was the toe of the shifter, which I tapped and put a bolt in. Ground the crap out of the stator cover. I just got a deal on another for 70 bucks. And the aluminum piece that the chain tightening bolt presses against broke and bent the bolt a little. The little ear the the swingarm spool screws into bent alittle. I straitened with a brass hammer. No plastic damage what so ever, didnt even touch the bar end or clutch lever. I am just lucky there were no utility polls or road signs.

My experience is that most people don't know what goes wrong when they crash. It just happens so fast and they are left to wonder what they did wrong.
It's possible that the REAR tire slid out on you if, when the bike hit the ground the rear still had momentum to spin around and throw you into the ditch back first. If you ever see racers crash, whenever they lose the front the bike tends to stay going forward while they are left behind. But if they lose the rear they slide in front of the bike because it pivots and spins them around.
Maybe you twisted the throttle a little too much, maybe you tapped the rear brake accidently.
When I crashed my first and only time (knock on wood), I was coming down a mountain road and I didn't realize how steep it was and how fast I was going. When I came to a curve I started applying brakes when I thought I should and they instantly locked up. The only thing I could do at that point was scrub off as much speed as I could before I flew off the road. And then I hit the ditch head first. I was wearing a helmet of course or I wouldn't be typing this today. I was knocked unconscious but at least my thick neck I had from working out all the time kept my neck from being broken.
That was my first bike--Ninja 250. The bias ply tires and single front brake rotor simply couldn't handle that steep mountain road.
Now I am sworn off performance street riding. I have an empty parking lot nearby where I get my lean on (all the way on the Gixxer 1000--spinning the rear tire and wheelying off the exits). Mountain roads are just too dangerous for me.

Um.....so you spend your time riding your GSX-R1000 in an empty parking lot?
Don't blame the "bias ply tires and single front brake rotor" or "dangerous mountain roads" for your crash. It's called "rider error".

Of course it was my fault--but the single brake rotor and bias ply tires (not to mention the loosey goosey suspension) of the Ninja 250 certainly didn't help the situation. I can brake much better and faster on my Gixxer. But I'm not willing to go riding down a hill real fast into curve I don't even know what looks like just to prove it.
And yes, I HAVE FUN in an empty parking lot. What's wrong with that?
Check your ego and lighten up.

And your point? You don't believe me, or are you saying I should be more modest? I'm just telling the truth. I want other riders to know that they can still have fun in the relative safety of an empty parking lot instead of going 150mph on freeways or popping wheelies in traffic.
A lot of us don't have the time, energy, or money to go to track days. But you can still learn about WHEELSPIN and throttle control, as well as trail braking and corner speed at an empty parking lot.
Now tell me I'm wrong cowboy...
