you got it the other way around son, if we are talking about a car of the same caliber as a bike (a watered down racecar vs a watered down racebike) the car will always win cars-better brakes, higher top speeds, more traction, and it takes less time to switch directions bikes-weight to power ratio of course it all comes down as to what kind of racing, and where, 1/4 mile, bike wins. Long highway run, car wins. Track with alot of turns, car wins
