Moving objects, motorcycle riders included, cannot diverge from a linear path without lateral g's. It takes force and acceleration to move in anything other than a straight line.
My point was that throwing out a lofty lateral g figure without mentioning that it's in a highly banked curve is misleading, sort of like quoting an awesome 0-60 mph figure, but not mentioning that it only applies on steep downgrades.
