Why are MotoGP bikes so fast?

An inline-four, with its extra crankshaft gyro, is more difficult to divert from its trajectory when the rider wants to tip into a corner, but once the bike is in the corner that gyro helps the rider maintain his line. This is one reason inline-four MotoGP bikes are faster through corners.
