The throttle never comes off, the bike rolls on its own. FULL GAS is
the throttle wide open, and it goes much faster, but it pulls the front
wheel up into a wheelie.
And that is the game: the front wheel only stays up on flat ground.
The moment the ground climbs or breaks up, you go over backwards. Let go
before you get there, or brake to drop it at once.
In the air the button does the same thing, it lifts the nose, and fast.
BRAKE drops it. Let go of both to fly level.
Careful, there are no exceptions in the air. If you take off with your
finger down, it keeps rotating, and it makes no difference whether
it was a ramp or a bump.
Land with both wheels ahead of you.
And there is the prize: a flip in the air is worth one nitro, and
every nitro makes you faster for the rest of the run. You do not have to
nail the full 360, three quarters of a turn already counts, as long as you
land in one piece. Going all the way round a loop pays too.
Crashing empties the tank.
Your best lap is kept as a ghost. It runs beside you on your next
attempts, and when you finish you can send it to someone in a link so they
race against you.
Loops are taken with speed, not with skill. Go in fast and keep it
wide open.
