While surfing the Yamaha website I found this little gem from 1980. Please enjoy the trip down amnesia lane.
The Tri-Moto was the first Yamaha ATV sold in the U.S.A way back in 1980. It featured a 123cc two-stroke engine, Autolube oil injection system, CDI ignition, a snorkel air intake and a five speed transmission. It was designed to be a durable workhorse as well as the ultimate recreational vehicle. Voted one of the most ugly ATVs ever by Outdoor Life.
