60~70 mph turn the bike hit gravel was upright but sliding till it hit the curb threw me way up in the air. Observers said about 15~20ft. Landed on my feet. Bt the bike went all the way to the runway. Me and my buddies were able to get it out of there before SPs and Tower noticed.
Sliding been pretty Lucky, normally start sliding maybe 5 feet then all of a sudden I am up and running. Must be an instinctal thing from all the crashes when I was younger and street skiing behind a truck.

Why did you post this? Are you a masochist???? :cry:
I posted this because I always went back and measured how far I slid and was always amazed at the distance and the shape I was still in. I wanted to know what the normal distance was. I also thought that if someone could come up with some kind of constant to show how far a person would slide from a given speed maybe people on this board would respect the speed of the twelve a bit more. Maybe save sombody a bit of road rash. You know, make us think a bit more, as in being a bit more educated, smat, knowledgable about what will happen in a high speed crash. I know what it feels like and what the results are of a 60mph crash if you don't hit anything. I am a three time winner at that. I don't know what 100 or say 175 mph. would do to a person. I would like to know before and when I am taking the risk and cranking that throttle up. I don't think if you double your speed your slide distance doubles. I think if you double your speed your slide distance more than doubles, but I don't know by how much. That is what I was wanting to know.
I appreciate all the posts but was, along with these coments, wanting sombody who knows about these things to give us a number that we could use to determine the average slide distance at a given speed by multiplying the speed by said uknown number to come up with the average distance.
I don't think I am sick or anything. Just wanted to know what I was up against so I can respect my speed apropriatly.

If that s what you are looking for then, it would definetel be compltel different for the rider and type of clothing they had on.
If somebody knows the coeffcient of friction for [leather or skin] and asphlat (I willl try and look some of them up) Then it would be a freshmen kinematics problem.

uk I have solved based on an average speed of 60 mph = 300ft slide.
Then using this information I came up with the following simple formula for everone to use. I have posted results for a few. Remeber thought this depends on what you were wearing I am pretty sure leather (that most of the motorcyclist wear) will slide farther than skin (i.ie. jeans t-shirts etc)
Meaning you will lose more skin to microkinematics to slow down than leather will.
[(Vi)^2]/(26.2752ft/ss)=distance you will slide (for ease I made the calc = feet slid those of you metric divide by 8m/ss)
using feet/ss you must convert miles per hour to feet per second
using km/hour convert to m/s (this is easy for you metric guys)
Data due to some rounding is ever so slightly off.
10 mph = 8 ft
30 mph = 73 ft (some of you must be standing up early)
60 mph or 97km/hr = 295 ft or 90 meters
90 mph or 145 km/hr = 663 ft or 202 meters
120 mph = 1178 ft or 360 meters (I think most people are hitting other things to stop the slide at these speeds plus we are negleting air friction which would definitely shrink some of these numbers, calc for air friction if requestedd will have to wait till i wake up if anyone is really interested)
200 mph or 322km/hr = 3274 ft or 998m (almost a km! neglecting air friction)

I don't have an exact speed but two years ago a sixth gear wheelie went bad, I passed my buddy on his gixxer 1000 and he said he was doing 280 km/hr and I easily passed him on one wheel.
The cops said I slid 1.2 kms and the bike went 1.7 kms, I was in full kawi race gear thank god or I would not even be here. It was on a flat stetch of highway and my leathers wore through all the heavily padded and steel enforced plates. My buddy said I looked like a rag doll and he thought when he stopped I would be dead for sure.
I don't remember the air ambulance ride but I remember the pain when I woke up, luckily by miricle or supreme intervention no road rash.
Seperated left shoulder, all left ribs fractured, dislocated left hip, dislocated right shoulder, broke my left knee, broke my left ankle and also my left elbow.
Two years later and three surgeries later I am still here and riding.
I agree no more 6th gear wheelies for me.

King, glad you made it through the ordeal.
Before the accident had you ever rode while wearing shorts?
And after the accident same question?
Just figured you would tell everybody to buy and wear their leathers.

Wow that sounds painful King. You were obviously close to 200 hundred or it was a slick area. Or on reading maybe all the rag doll movements kept you off hte grround for some time causing you not to slow as quickly another thing we would have to add to the calcs "bounce factor" :lol:

Never rode in shorts never will, short sleeve shirt guilty.
Bounce factor I believe is relevant.
I really believe in wearing full leathers on the street but I still go out jacket and gloves only, even though they saved my life just stupid I guess. The pics of me doing wheelies on my page are last summer in Florida nothing but jeans and tee shirt and leather gloves just goes to show how dumb I can be I guess.
I have been riding since I was 5 years old and now am 38, have broken almost every bone in my body at one time or another and almost all a couple times. Just a show off at heart, think by the penis die by the penis god made a mistake with me he only made my heart large enough to supply blood one or the other brain/penis and the latter seems to always be on duty.

Do all the broken bones and fractures come from the fall at that speed
or something about the speed that does it? I mean if you low side in a turn and fall 12" or ? onto your padded,reinforced,leathers.. you slide until you stop... if you fall over backwards or highside, then you are falling from anywhere from 3' to 5'+... that is what hurts? opinions? experence?
Again, I only have my 1 over the handlebars exper. to deal with.

Just a personal opinion here.
A couple of riding buddies of mine tell me to tumble when I go down. That way I will spin like a tire (Yeah right, square tire maybe) and not get as much road rash.
I feel like spinning or rolling is just asking for broken bones. As long as I am on a smooth surface ( blacktop, concreet, gravel, or dirt) I have always tried to get me feet sliding in front of me. Don't ask me how it just seems to be a natural reaction for me.
My last get off at 65 mph. I remember going down on my right shoulder. I remember sliding on my right shoulder and face. Next I remember my feet, legs, butt, and back up in the air and my right shoulder and back of my helmet grinding away down the blacktop. The rest of my body came down and I remember squirming around to get my feet in front of me. I got them in front of me pretty fast and then set in for the long slide. I remember leaning to the left until I felt the left part of my butt getting hot and then I would lean to the right until I felt the right side getting hot. Then back to the left and I repeated this untill the ground stopped passing me by.
All of this caused by uneven pavment. Left lane had new blacktop for about 200 feet further then the right lane. No construction signs warning of this either. I just happend to get lucky and change lanes at night at that exact 200ft spot just after calmly passing a minivan. Glad he missed me when I went down right in front of him. When the left side of my front tire caught the higher left lane and the center of my tire caught the lower right lane my bars went full lock to the left instantly. Not a scratch on the left side of the bike but I sheard of the left side footpeg trying to hold her up I guess. Can't think of any other reason the left peg would shear off. The peg was hinged (you know the setup) to fold up so the force that sheared it off must have been a downward force. The same one I was aplying with my foot I assume.
No broken bones. right shoulder was the worse problem. My JC Penny leather jacket failed to save me. The two collar snaps unsnapped and the zipper up the front came down a fourth of the way just enough for the jacket to pull back over my right shoulder and expose my shoulder to the blacktop.
Yes I slid about 350 feet with the bike going another 40 feet.
I remember the bike coming to a stop in front of me. Hearing it idle and knowing there was no way it had any oil pressure on it's side like that.
Then it died. I picked her up and my good ole Kawasaki Ninja 750 fired right up and took me home even though it was missing a few parts.
Be carful out there, remember sombody has to be next.

About 200 yards at 140 mph. That was what was indicated going into the corner when the front end went as I was getting onto the straight. Then I hit the 10 ft concrete embankment. And went over the embankment and the 6-ft bushes at the top (trees,sky, trees, sky as I rolled over). And back down onto the road the other side.

Jeans, steel-toecapped boots, leather jacket and gloves. Toecaps wore down to the steel. Gloves went through at the palm. Jacket went through at the elbow. Legs, well let's just say I was wearing shorts and slops to board meetings at work for the next 3 months.

Cracked and scraped a few bones, lost a lot of skin, but didn't actually break anything until a cracked wrist bone let go 2 weeks later.

It is always ouch in my opinion any speed will do, at close to 200 mph it doesn't matter what you do you are a rag doll trust me on this one. The only thing you are thinking about is your family and if you will ever see them again.
I forgot to mention the insurance company had to replace everything $23,540.00 damage not including the benifits for being off work two years. I guess it is my fault for high rates a little sorry guys.

Talkin' 'bout this sh*t drives me nervous!

All I know is, when I was a kid & fell off - I went home & fixed my bike. Now when I fall off - I go to the hospital & call the insurance man to fix my bike.

Remember when you were unbreakable? What the f*ck happened to that?

I don't remember being unbreakable but I know I used to be indestructable. WTF happened older wiser no I don't think so hmmmm.

I hit a pot hole in the road that is what caused the see ya later I looked over the post and relized I had not put that info up sorry guys. It was a big crack in the ashphalt about a foot long and 4 inches deep by 3 inches wide. OUCH!!!!

Damn...which time? Been down, up and over twice...one time
I gained altitude because of so much air under me...oooh, flying!
Felt like the flying squirrel...

One time I thought I was stopped, so I put my foot down to stand
up, and I guess I was still dazed...anyway, I was still going about
35mph...so I launched again...and the second time hurt a lot more
than the first fall...

One time I slid so far that I felt my leathers getting hot, so I rolled
over on my stomach to use fresh leather, and I tilted my head down
and ground off most of the front of the helmet...no road rash at all!!!
But my butt was burned from the heat...

Another time I grabbed the font end of a Jeep as he was about to run me over...he was right behind me when I blew a wheelie over backwards,
we were going about the same speed, and when I looked up he was right there...I held on till he stopped...heels and sides of boots gone.

Geez...why do I ride these things??? CAUSE I LOVE "EM!!!!!!!

You know...thinking about this for a while...I haven't been down and
busted up in almost 2 years...DAMN....I'M OVERDUE!!!!!!!

It's time to punch another ticket to the house of pain!!!!

Think I'll stop in and say hi to all my friendly nurses that always
patch me up....

"I have gone down at 60 or 65 miles an hour 3 times now."


Do we start to see a pattern here?

Perhaps your time would be better spent figuring how to stay upright on a motorcycle rather than computing your next slide distance. Three strikes you're out?

Maybe another "sport" would be worth considering?

Best wishes
