I had a 10' CBR 600, at 150 it was pretty scary: smashed face into the tank with so much wind that if you moved it would pry your body off the bike and you also tunnel vision. That being said, the distance that you actually went that fast was not very far. Now I enjoy passing sport bikes and maintaining speed for a prolonged distance, in comfort, with music playing, legs on the highway bars...and watching them scrunched down staying out of the wind
