Cheat: Max Out Stats
The following exploit forces you to mess with computer files and in-game files. Because of this, attempt the following at your own risk.
Head to your Pure installation folder and find the path entitled Data-Vehicles-Handling-Tuning. Open up the DefaultTuning.params file in Notepad, which will allow you to change the values (make a backup of this file in case you mess it up and want to replace it!) Modify the numbers found near StatModifier and StatBase (the numbers appearing in parenthesis represent the set values). Set them to their maximum value, and head back to the game to take advantage of your new-found exploit!

Hint: General Tips
1.) If you can’t place in an event, move on and come back to it later. Winning other events further in the Tour will unlock new parts to beef up your bike. Then come back and ace those troublesome tracks.
2.) Finishing the World Tour requires you to get 1st place in every event in the 10th stage. Do this, and you’ll unlock character-specific ATV shells for every character in the game.
3.) In Freestyle events, go for the Star powerup as early as possible. The sooner you can pull off a special trick, the better.
4.) Holding down a face button while doing a front or back flip will modify your flip and give you even more points/boost.
5.) A purely freestlye bike isn’t always best for every freestlye track. If you’re having trouble winning a freestyle event with a freestyle bike, try your race bike instead. Sometimes being fast over jumps is more important than getting air.
Enjoy
