These pictures of a Viking Prototype were acquired, along with the sled, from the "gentleman" who actually built the sled in the R&D department.
The sled was built in 1973-74 in the R&D department of Viking. Note the use of the 1976 style hood and belly pan. The sled has a Kohler K4402AS
engine and uses a jack shaft with hydraulic brakes. The sled was first built with a jackshaft and an Apex brand chain case, but an Arctic Cat chain
case was swaped to add the hydraulic brakes. The Chain case and brakes were bought from Arctic Cat and were being used on the 1975 Arctic Cat Z.
The pictures here were taken 1973-75.
The sled was originally built with a para-rail suspension, but when the Arctic Cat chain case was installed, an Arctic Cat El Tigre track and
suspension were installed. Note the exhaust and steering rod in the 4th picture.
In the 5th picture the sled is pictured with an early version of a hood to be used for the 1976 model year. Take note of the silver 1976 belly pan.
When the 1976 models were being produced a windshield was added.
Today this sled is owned by me, and still looks the same as in the first 3 pictures, but with the 1976 windshield added.
The sled is currently on loan for display at the Heritage Center in Twin Valley, Minnesota.
