I tossed it out more to direct the conversation to the scramblers - I'm no encyclopedia on Honda's or Triumphs, BSA, etc..
Calling a Zundapp or BMW a dual sport is ridiculous unless your also prepared to call the Harley and Indians of that era dual sports.
I don't have a problem calling BMW the king of dual sport motorcycles, I just don't believe they marketed the term first. Perfectly willing to be concede I'm wrong there.
