Summary: This game destroys sbk x in every way. I love bikes so had fun with sbk, but when i got a chance to try this game i went and baught it right away. The physics have MUCH more sensitivity. You actually fell like you can lean and your rider has weight. There is a real sense of speed and great AI. VERY rewarding to custom tune your bike and win the race. it gets very intense and has stayed fun every day i play it.
