Before experimenting with leaning your bike forward or back, judge
the decline or incline on the stretch of course where you hope to 
land.

Use the behind handlebars viewpoint for the most realism, the best 
sense of atmosphere, and (surprisingly) the easiest gameplay. 

Use prize money wisely. It's better to spread funds across several
areas of the bike instead of focusing on one of its aspects, as the
latter tactic is detrimental to your bike's overall performance.
