Motocross Madness

Okay to get this achievement simply start up the first trick session in Egypt when you unlock it, this may take a few races and rivals events. I did this with a fully upgraded Lancer but I'm sure a lower level bike could do it too as the score required doesn't seem too high.

Now I advise you just keep doing the huge pyramid ramp in front of you and do whatever tricks you wish. I myself did the Y+Left tricks but you do need to unlock these. I also finished with some B+Left tricks which gave me some nice points. I would imagine if your just starting out then you'd only have the X button tricks but they should be able to do it too hopefully.

The pyramid has a ramp on both sides so simply turn and get a good run up and do it again! I did this several times and it gave me a brilliant amount of points each time, also try to grab the score bonuses above the pyramid.

Video below showing my exact method.

You can do this and unlock the achievement 'seriously?' at the same time. Hold LT + RT and turn left to do a donut until time expires. Nice and easy.
