CLARKE MANUACTURING CO INC.
Welcome to the Clarke Manufacturing Company Inc. In the beginning Clarke started out wanting a custom
fuel tank for himself. Clarke was tearing up the flat track in Portland Oregon as an enthusiast of the sport
Clarke Hoeltke told his wife Virginia he wanted a cool tank like the other racers had. With 3 daughters he
knew he could not afford the additional expenses for this fancy fuel tank. He made his 1st tank in the
basement of their home in 1963.
Time went on Clarke knew he could do more projects with fiberglass. With the help of friends and family
Clarke and Virginia started the Clarke Manufacturing Co. in 1965 in Milwaukee, Oregon where they
produced tanks, fenders, and seats.
The Early 70’s Clarke had started riding in some enduro events and knew he needed a larger capicity fuel
tank. Clarke started reading up on Plastic Polymers and because of his Machining background he new he
could create a far better and more durable fuel tank. The building of the rotational molder began.
By the mid 80’s The Clarke Mfg Co. Inc. had tripled in size forcing Clarke to start hiring employees, branching
out into the 3 and 4 wheel market for agricultural.
During the late 90’s the Clarke Mfg. Co. had a fire, destroying all the fender molds vacuum former and the
rotational molding area. The building was destroyed. Unsure of what they were going to do Clarke, Virgina
and his family started looking for new property.
