A friend sent me a photo of this clean chopper with a motor I've never seen in a chopper.
I did some googling and found that Yankee just isn't a cool name given to this chopper it was an actual American made motorcycle in 71-72 by a Yankee named John Taylor who was a Bultaco and Ossa importer.
His creation started out as a Ossa 460 modified into a 488 with two 250 cc top ends that resulted in a twin or a twingle.
Dick Mann engineered the frame and good ol' Smith and Wesson forged the triple clamp. Whoda thought a gun maker would jump in on this one?
The bike, like a lot of American manufacturing, was over built making it 344 pounds dry so it over shot it's intended market. Only 764 of his bikes were ever produced showing once again that us 'Mericuns just can't get ourselves to make cheap throw away motorcycles.
That is a big honkin frame. Made to last, I guess, but me thinks with enduro's lighter is better.
I'm sure it would take more punishment that the the other guy's but once that frame is bent it would take more than a good swift kick to straighten it out.
If kinda reminds me of an FXR frame which was costly to produce but stout.
