The Trail Boss was a stylish entry in the enduro market with plenty of chrome trim. Even the heat shield on the exhaust and chain guard was chrome plated. Compared to the DT-1 or Honda four stroke enduros the Trail Boss is much more rare and you hardly ever see them for sale, let alone in unmolested condition. This bike is claimed to be all original, even the seat. I seem to remember the seat having heat embossed ribbing instead of a flat expanse of vinyl as in this example, but no big deal, there is a guy in Canada making excellent reproductions.
This example has 1,800 miles on the clock and comes with a title and original owners manual. Given the pictures in the ad, I would have no reason to doubt the odometer. Also, looking at the pictures, the tires look original and should be changed if you are going to ride it and not hide it. Other than that, it looks like its ready for tiddling around your neighborhood.
