The coefficient of drag is just that, a coefficient.
You have to multiply it by the total frontal area, which is significantly smaller on a bike than it is a car to get the total drag.
I am assuming that the rider is wearing race gear, a good helmet, and is using a race tuck riding position...
And either way, I don't think drag has all that much to do with the race until 120 mph or so, and honestly going any faster than that on a public road isn't a speed contest, it's a retard contest.

The ZX-12R has a frontal area of 6.09 ft2 (0.566 m2), physically larger than the Hayabusa, which is 6.01 ft2 (0.558 m2). But the advantage for the Suzuki is not just in frontal area. With figures for both drag and frontal area, it's possible to calculate the coefficient of drag, which is 0.603 for the 12R and 0.561 for the Hayabusa. The winner of this wind tunnel shootout is the Suzuki. It's worth remembering, however, that neither of these Cd figures indicate a particularly impressive degree of streamlining, since even a typical passenger car has a Cd of less than 0.60 and some models are lower than 0.30.

It is generally accepted that, on a typical car, its rolling resistance and aerodynamic drag become equal at about 50 mph. So at twice that speed the aerodynamic drag is about 4 times the rolling resistance.

0-60s on most motorcycles range from under 3 seconds to 7-8 seconds. Prices are around $5k to $12k. 0-60s for most cars range from 5 seconds to 12 seconds. Prices are around $12k to $35k. The FD has a 0-60 of 5 to 5.4 seconds. Drag spikes up rapidly as the cube of speed. That means if you aren't close to the bike's top speed, drag is a very small factor. Bikes have a low top speed, but it'll still be over 100mph (even 150mph++). Bottom line is, you'll cream the run of a mill motorcycle but any good sports bike will beat you.

Sorry but again you don't know what you are talking about. He was seasoned rider, raced at VIR and knows how to ride. I have raced more than one 900 rr with the same results and btw he weighed 165 lbs.
