As the name suggests, Simulation offers a more realistic, deeper - sometimes frustrating - challenge. Braking in a straight line without lock ups, hitting the apex while cornering, accelerating gently to prevent the back wheel from sliding...basically, putting yourself in the shoes of a true Superbike professional. To increase the difficulty, the superimposed racing line is completely removed here and replaced by a small icon at the top of the screen (similar to those used in rally games) that will warn you of the upcoming corner. It will also change colors to point out slowdown or breaking zones. http://sbkxer.com/lNL5i
