This post has video walkthroughs for all the MotoHeroz Treasure Chest Locations that are hidden throughout the game. You can find 1 on every stage and each contain 50,000+ gold. If some treasure chests are too difficult to reach you may have to upgrade your vehicle.
Most of the the time the difference between a stage seeming impossible and being too easy is just using the right power-up in the right location. Pay attention to the ghost as he will seem to take an unfair advantage at certain points in a race. Those spots are usually where you would use a power-up.
