Let's see.. in chronological order...

If you are a kid on a dirt bike, look both ways before crossing the street.

If a driver is sitting there as if to wait for you to pass, don't assume they see you and won't pull out and T-bone you.

Cold tires slip unexpectedly at surprisingly slow speeds. A motard with the acclaimed "Avon Distanzias" will still dump you on your ass if you do not allow the tires to warm up.

If you see your wife and kid outside watching you come home on your bike, don't be too big of a jackass riding wheelies up and down the street.

Dang I wish I'd heeded that advice, would have saved me a lot of grief.  

The front brake is a wonderful tool for slowing down quickly. Applied, even the SLIGHTEST in a "Compromised traction" situation, like, say, on a gravel road, or rolling slowly to a stop sign & theres sand in the road,, & by Slowly, I mean so slow that when that guy touched that front brake to finish the stop, his bike dropped from under him like he was riding a dog & someone shot it out from under him,, & he was standing there with the bike on its side between his feet,, I saw the whole thing,, yes I did,,
Boy that felt weird,, & I felt stupid standing there.

I was setting up to turn around on a gravel road,, slow, not over 10 MPH,.,I Touched the front brake & went down so fast my feet were still on the pegs when I stopped sliding.

WOW!  & all before You Tube I guess,.. That gave me a great mental image, glad you made the whole flip.,.

Oh, I forgot about those low speed fall overs !

Once just like Jog seen,......I was making a very low speed U turn on sandy pavement,......touched front brake,.....not good.

And how could I forget this one,.............
my bike fell over dam near on top of me while I was standing on my head checking my oil,.....doing it the very stupid SUZUSKI way !

1973: Hopped on my wife's little Suzi step-through to go to the store to get a quart of milk. In shorts, sandals and a t shirt. (I was only going a couple of blocks, right?) The city had started a repair at the entrance to the plaza and left it with oil and p-gravel on it. Down I went, slid about 20' on my side. Got the bike up, straightened a bent foot peg by kicking it, and went on my way to the store. I must have been a bit shocky because I failed to notice that blood was dripping off my fingers, running down my leg, and the place between my big toe and the next one was split open. That sandal was gone too. I went to the back and got the milk, and while I was paying for it, I noticed my hand was all bloody and asked for some band aids too. The teen aged girl behind the counter looked a bit pale but got them for me. Got on the bike and drove home, where my wife had me stand in a cold shower to stop the bleeding while she picked bits of road out of my arm and leg with tweezers. Then off to the hospital to get the web (?) between my toes stitched up.
I ave a peppering of barely noticeable scars on my arm and leg and between my toes.
Needless to say ATGATT from then on.

I've only been riding for 13months and barely 11,000miles.
No lay downs or drops, yet.

But now I'm in that dangerous period from 1-3 years of riding where it's likely that I'll feel brave and think I know more than I do, and go beyond my limits. I know I've been pushing those limits further and further for the past few months.

been riding since 1991, (i was Four...) racing dirt since i was 14, as well as the street off-and-on from the same time. (my first bike, a 1984 SL125 when i was a Sophomore, spent more time under the wrench than actually running   )
You can't count the Motocross or Desert wrecks, but on pavement i've been down once- and it led to me buying the Savage i was riding. See i was house-sitting for a friend while he was away, and he told me to "ride the $#!7 out of that little thing" - the 'little thing', of course, being the scuffed up, already-been-dropped-several-times,  not so pretty 2001 Savage he got for his wife to learn on. I thought what the heck, it will be cheaper than my truck on gas, and it's excellent riding weather in Georgia in the summer time! only problem was all that gravel and dirt in the flat left hander at fifty-five miles an hour. i got slowed down a little, but by the time i got in the sand/gravel death mix, the ol' savage wasn't wanting to turn any more and that barb-wire fence was coming up fast. So I hit the eject button. Well, all my moto training paid off in learning how to crash, because before the bike stopped rolling i was on my feet chasing after it. it landed upside down on the handlebars like you used to do when you needed to change a tire on a bicycle, and wouldn't you know, it was still trying to run. i flipped it over, kicked the bars straight and stabbed the start button to get it re-lit after flipping it back over, kicked down to first gear and took off out of there to get back to the house before anyone saw me. the bars were mangled, the right mirror wouldn't stay up, it kept swinging down and smacking my hurt wrist, the left footpeg was permanently folded up, and it broke off the steering stop. got 'er home and laid in bed for the next day and a half. I somehow got road rash through my jeans, even though there wasn't a mark on them. Tee shirt wasn't much protection, but my excellent tuck-and-roll tactics kept the abrasion to a minimum. Leather steel-toes didn't do much for a 350 pound hunk of steel landing on my foot, xrays proved later i cracked something called a "tarsal", whatever that is   i also sprained a wrist and "bruised" a rib. all this would be fine and dandy, if i didn't have to do my M4 qualification that monday, my wrist didn't like the abuse at ALL. after all was said and done, i fixed what i broke but there were some scratches on the metal and a dent in the tank, plus the steering stop broken, that i couldn't fix at the time. My friend had no problem with me dumping it, but wanted it fixed so he could sell it. I simply offered to buy it for the cheap transportation- and now i'm here! funny how stuff works like that.

Moral of the story: Don't ride a cruiser like a sportbike, especially in limited traction conditions!
