Columbia Observed Trials Assn. (C.O.T.A.) , as a Trials club was formed in the early 70’s. The Trials story in Oregon begins with the intoduction of what was initially called “English Trials”, which was introduced to America with the introduction of trials specific motorcycles. Montesa’s, Bultaco’s were the first serious trials motorcycles to make there way to Oregon. It is rumored that the club name Cota was inspired from the Montesa Cota. Shortly after the Montesa’s and Bultaco’s arrival, the Japanese manufactures entered the Trials market, introducing the Honda TL 125, Yamaha’s TY 80-175-250, Kawasaki KT 250, and Suzuki’s RL 250. Inexpensive Trials bikes were readily avaialble, which inspired the “hay day of the seventies”, hundreds of riders would attend local trials.

Since the seventies, many bikes have come and gone, events have been held in many locations, popularity has risen and fallen. Now our events are staged in the Tillimook state forest, Mt. Hood National Forest, and private land. On average, a local trial atracts 30 riders. There are 70 to 100 riders that make it out every year. Trials in Oregon is very small group.
