Yes, these speeds are very doable with modern crotch rockets. The Hyabusa, while testing, was having troubles. Seems that when the bike reached 180 MPH, the force of the air was enough to trigger the front brake lever, causing the tail light to come on.
I have went faster in cars than on bikes. I had my buddies Ninja 600 on the freeway once. I was cruising about 70 MPH when I came up on a group of Harleys. I appreciate all types of bikes, so I gave them all a quick "wave". A couple of them started revving their engines, and before I thought, I just downshifted, and watched them get smaller and smaller in the rear view mirror. I only hit about 107, but it got there real quick, and the bike seemed very happy at that speed. That was fast enough for me. 200 is nuts, especially on a public highway.
On Dave Despains show, he called the guy an idiot. He said he was not impressed with 205. He showed a pic of someones bike on the Dale Jr. pit crew that will do 250 MPH in street trim, and said "now THATS impressive!". LOL
I now have a son and a will to live...I dont need another bike!
