Bikes don't have to worry too much about lift since they are narrow and it is difficult to get air underneath.
Is this true? I would argue that when leaned over, especially at race speeds, lift becomes a major issue. That is why I make the comment earlier about drag not being the only measure of aerodynamic efficiency. Motorcycle land speed racers work great in a straight line. I would bet that making a turn is a whole other ball game.

Speaking of sonic and sub sonic flight, a little trivia...Can anyone guess which aircraft design was the first to come to grips with the air compressability problem? Hint Hint WW2? I will post back later with the answer.
Which air compressability problem -- are we talking about the wing issue or the engine-feed issues for various engines?
For wings, I'm guessing your talking about the Messerschmitt (ME262) swept wing design, which actually originates in the earlier Pfeilfluegel II.
On the engine end, there are a host of aircraft that qualify, some dating to prior to WW2 as well (and the V1 buzz bomb with it's pulse-jet also plays games with air compressibility).
Cheers,

Ain't this debate fun. First forum I have ever been in and a discussion not turned into a flaming potato. Katana riders must be very mature and obliging!!
