Annual 4-Stroke MX Championship at Glen Helen Raceway “The sound of thunder isn’t just during storms anymore. It’s being heard more often in Motocross. At Glen Helen the rumble shakes the ground most noticeably during the 4-Stroke Championship. Each year 4-strokes gain in popularity and each year this event continues to expand right with it. The Pro Purse gets all the top riders out into the storm and the chance to be crowned World Champ brings out just about everyone else. Last year over thirteen countries were represented from all over the world.” - Glen Helen Raceway Now, it’s your opportunity to be the Factory rider you always wanted to be…or at least be treated like one.
