Can anyone help me out with setting up my gears to make my bike go faster. I am using a automatic, since the manual gears are too hard to me, lol. Thanks.

There is absolutely no best setup for gears.  The gearing u should use depends on how you plan on attacking the corners.  Will u be a brake slider, a powerslider, a burner, a sim style guy, all will benefit from custom gearing towards that style of attack.  Actually play the game for about a week instead of achievement whoring and posting in forums for quick answers.  However, if you have legitamately played then go to XBOXLIVEADDICTS.COM, Its where I met all my fellow GP racers and there are gear ratio's out the wazuu for you to play with.

Yeah dude, I have played the game for about a month straight when I first got my XBOX 360. This was the game my console game with and although I thought I was alright at it, it just got more difficult for me. I love the game very much, but I stopped playing it after getting to a point in the game where I couldn't keep up with the computer riders. Thanks for blasting me on my achievements and I will check out that site you mention. Take care dude!
