Yamaha XT550 Ténéré Prototype

.

A strange idea?
  

  Of course Yamaha's European product planning picked up on this new market 
  trend. They caused a surprise in the Yamaha Japan headquarters in 1981, when 
  they suggested to produce a replica of the Rally machines with a 30 liters 
 
  fuel tank and a big single, or even a twin, engine. This was a concept hard to 
  understand in Japan, where the adventure dream had not picked up yet, and  
  nobody could imagine normal motorcyclists wanting to ride around with these 
  big fuel tanks.

  But the engineers finally took up the challenge and created the first Ténéré 
  for the model year 1983!Source
