Introduced in 1965, the Suzuki K15 (also known as the Hillbilly) was a 2-stroker for the trail with features like a skid plate, luggage rack, and swappable sprockets.
Basic specs were a dry weight of 155 pounds, and 7.3 horsepower from the 80cc single. Top speed with the trail sprocket was 38 miles per hour, and 60 mph with the street sprocket.
This example runs on premix and comes with some spares. The seller notes that he “lovingly restored everything but the seat, titled and plated in FL.” Find this Hillbilly for sale in Central Florida for $1,000 here on ADVRider.
