Wolf is a different Breed of Big Dog, perhaps their finest product. Feel that it is easily a $20,000 quality bike, especially all chromed like this one, however Big Dog has fallen off the radar for many, and a bargain price is going to be necessary to snag a buyer. Are replacement rear tires available in the marketplace. I wanted a Wolf about a year ago, but could not find any source to find their unique rear tires. Wolf is the total package. Great looking, smooth riding, good handling, and lots of power from the X motor.
