Why do ONLY the Harley's win the awards and trophys at biker shows?

different type of bikes shows like there is more harley's where your looking and that would be why your seeing more of them win.. sport bike have shows too and there a harley would be low on list way to express is vote for the bike you like.. or just kick over the winning bike now that would be a big expression of your outrage really they are other shows to go to sports bike harley like old car or truck they al have their on shows and its being there to look at them and what doe it matter unless your bike is not in there with them
