There must be some reason that nearly every track record is held by a
4 wheeled vehicle.

Cite?

A couple of results from a quick google. You can do the rest of the work.

Pretty much the only tracks where you'll find faster times for bikes are the tracks specifically designed for bikes. Cars obviously enjoy enough of an advantage from their superior traction, brakes and downforce that it negates the bike's advantage of less mass and better power/weight ratio. Not by a lot, but 6 - 27 seconds (the diff in the examples above) is a lot on a track.

Have fun.

Let's see. All tracks made exclusively with cars in mind. Now, how about
REAL cites? How about the physics behind your ASSumptions? Superior
downforce??? You DO realize, don't you, that a motorcycle, when it leans
INTO the curve is keeping it's CG in line with the forces, while a car
isn't, correct?
