A "moto hoe" is a female that attends motocross races (be it amateur or professional) simply to gain the attraction of motocross racers and to potintually have sexual relations with them. Their knowladge of motocross is sometimes non-existant, but they will still ask for your jersey after having sex with you. Also, a "moto hoe" that goes for strictly A riders or pros, would be considered a "pro hoe".
"Check out that moto hoe in the mini skirt and Lawrence jersey!"
"Well, you know how she got that jersey, right?"
"Let's call her over here!"
