it turns out that suspension matters...

It was a long day of work and I was so excited to get on my bike for the cold and dark ride home. I pressed the starter button and the bike roared to life, promising that my hours of effort had paid off.

I let off the cutch and gave her some throttle, which jolts me forward so much harder than any other bike I've ridden before. I pull out onto the road and I get cut off by a white truck which I would be stuck behind for the last 5 miles this bike will see for a long time.

Cruising at 55mph, the white truck suddenly turns on its left turn signal, giving me an opportunity to pass him on the right shoulder. The machine roars to life and I overtake him at exhilarating speeds of 70+ mph. 

Before I knew it, the frame became defiant, wanting to snake back and forth. I tried to control it, having never experienced this before. It only took a matter of seconds before the bull threw me off of its back. The last thing I heard was the tires screaming for help.

The next thing I know, I'm lying in the ditch next to the lifeless engine. I look around and quickly turn off the ignition. I check myself for wounds, which i could already feel. I called my brother to take me to the hospital because I could already tell that's was now my new destination.

I can imagine that the suspention is at fault, or my ignorance. I am very lucky to escape with a broken shoulder, collar bone, shoulder blade, nose, and road rash all over. This is just my reminder for those who have not addressed their suspention yet. It is VERY important to the stability of your vehicle and i hope my experience can help others learn from it, especially those close to me.
 
For those curious, almost everything looks good besides the front end and tail section, so maybe look forward to a project bike!

I get the idea this is your first “big bike”, the combination of weight and power will always punish inexperience ( cold tyres, slick surface etc) given the opportunity!!
Tank slappers are normally a result of a tyre or alignment issue, also loose headstock bearings. Backing out of the throttle will normally correct it (like a swaying trailer behind a car)

You live you learn... luckily I lived 

If this was travelling in a fairly straight line and not cranked over,  on a decent road surface it wasn't your suspension..
You should be checking tyre condition and  pressures as well as fork and swingarm bearings and i would have also said check the forks for twist or bent stanchions but you probably already have them now and possibly frame misalignment too.

This was on a straight road, so you're probably right. I hadn't considered the tires to cause something like this... Got any tips for checking frame alignment?

Edit: i should add that from what i can gather this wasnt the "death wobble" where only the front wheel starts shaking. The whole bike was rotating, which was why I got flung off. Tank slapper sounds to be more correct.
