Many of the Durty Dabber members participate in as sport known as Observed Trials. This unique type of competition is not about pure speed but rather a careful finesse of maneuvering the motorcycle over various obstacles including natural and man-made. The participants are required to make it through a timed section racing the clock and are not allowed to put their feet down (Dab) during the run otherwise face penalties. The Durty Dabbers participate in many events around the country as well as host one here in central PA.
