.....CB1300 - Dropped it...everywhere! Too fcking heavy!......Hayabusa - Dropped it 3 times - too heavy!

Bikes not to heavy, as you said you are not used to a bike which has weight so you lean in to far for speed you are doing..
Learn don't give up... after 18 months of riding my Busa I am just starting to throw it about.. it is a fun bike and responds well but I have been learning to not rely on my body picking it back up but more my wrist....
No doubt I will go beyond my limits and I only hope it wont hurt to much, but then if we don;t test our limits how to we improve?
I know I will probably never get close to my bikes limits though LOL
