Quad Extreme Racer is a challenging sport game on www.flash-games.net for free in which you can show your exquisite driving skill. The goal is to complete levels as fast as possible and achieve maximum score points. You can use up/down keys to move forward/backward and use left/right keys to move your center of your gravity on the motor bike. Maximize the score points by collecting bonuses and performing stunts, such as a 360 degree flip or a wheelie! But look out of crashing especially confronted with a peak or a valley. If you control your speed and position on the motor inappropriately, you will suffer a terrible crash which means the game is over. So are you ready to have an exciting journey?
