Make no mistake, the difference between 205 and 250 is about a bajillion horsepower.
Top speed occurs when the total drag equals the force applied thru the contact patch. If you apply more power to the contact patch than it can handle, the tire will simply spin and you will not gain any additional speed.
The real difficulty with bikes is the size of the contact patch. In order to apply more power to the ground, you need a bigger contact patch. The larger the contact patch, the less maneuverable the bike is. If you get a large enough contact patch, the bike won't steer at all, which means you can't keep it upright. It's a classic compromise.
