Thanks everyone.
Mouse, you probably were driving a motoike before you trauma, so you are used to it. For me - not realy. I was driving a mini-bike only, and in city, not in the highway, so do not have enough skills and have to gain them. I will probably take driving lessons in summer, and then let us see. On the motocycle, even the sliht wrong movemtn can lead to an accident, not even talk about a big jump...
Lisa, I am not realy in large superbikes, I like the motocycles which are not big but can go everywhere. But that sound logical that as you are being more concentrated on driving you are less likely to react on things around you.
Clarie, glad your bike experience was so positive :) I do love high speed and a risk, and I am a former skydiver. However, need motorcycle only for practical reasons.
Sill thinking about that, but thanks everybody.
