The point of the video was not to show an M3 beating a much slower bike.
The point is to show that there was no tire-spin in 2nd gear through 4th with bald 255's in an 800rwhp car (very cool accomplishment IMO). Full power can't be applied until over 100mph because of the tiny tires, and for those that have tried this would understand why. Streetability even under the worst conditions in a super powerful car is our goal and this video demonstrates that.
The HPF widebody car will lay the hammer down on bikes because it has very wide sticky tires and full power can be applied almost immediately.
