Motocross Big Air For Dirt Bike Off Road Racers. You ride your dirt bike hard and do things with 2 wheels most people wouldn't dream of doing with even four. You ride hard and hit the jumps fast and get major big air. Great gift idea for dad who is still able to do massive flips and tricks at motocross jumping competitions, perfect for the brother who still races hard every weekend at motocross events. Or maybe for yourself because you just love getting big air.
