Set up a public or private race (I chose A class) as myself and my fellow boost partner are not great at bike games and fell off our bike often, simply complete this race in the Sierra Nevada - Club Circuit as this is the shortest track in the game.
I had the following conditions:
Class: A
Physics: Standard
Transmission: Not Important
Laps: 3
Track Selection: Host
AI Difficulty: Very Easy **IMPORTANT TO HAVE THIS SET TO ANYTHING EXCEPT NO AI**
Private Match: Private
Good luck.
