Addendum: SOLD ON BILL OF SALE ONLY
Coleman Sports were fitted with the 25cc and 50cc engines. The 5.3 was a Sachs engine. These were marketed for use around a campground or carrying in an RV. Ironically, Coleman still sells mini bikes. This one appears to have led an easy life with only minor distressing of the paint on the rear fender. Of note, it is equipped with the federally mandated side reflectors.
