im a dirt bike guy. never owned a quad. but have ridden many. several years ago when i first started ridding i noticed quads everywhere. now i can go months without seeing a single quad. i live in Colorado and all the tracks i ride, dont allow quads on there pro level tracks. and i dont mind quads on the pro track. just not at the same time as bikes. im curious as to how everyone else feels about this topic. are quads dieing out?
