My first bike was a yamaha 600. I made it 1100 miles before lowsiding it in a 30 mph downhill decreasing radius turn I took at 70. Too much bike ? No. Too little experience to be sport riding? yes.
I wish you a speedy recovery and am so sorry about the hard lesson. I got off cheap. Totalled the bike and lost a finger nail. But I learned my lesson anyways...Got a Honda Hawk and took schools until I learned how to ride.
9 years, 3 YZF's, a F3, an SV, and now a '05 ZX6R, several CMRA race seasons later, but it is not the end of my learning. But let these be lessons to you all you don't have to learn the hard way. Go to the MSF school, take some riding/racing schools. Train yourself and be alert. That way you can have fun the rest of your"long" life.
