Vintage Motorcycle Show Introduction with the '36 Knucklehead & '37 Flathead UL

Every time we hear from Kevin, there is something to be learned. Whether through direct instruction or from conversation, he is a wealth of information on classic American motorcycles and know-how. At the vintage motorcycle show, Kevin shows us two beautiful pre-war Harley-Davidsons: a 1936 EL owned by Jerry Buffington and a 1937 UL owned by Jason Shovert.

Some background on these two motorcycles

In 1936, Harley-Davidson pulled ahead of Indian with their first overhead valve V-Twin, later deemed the Knucklehead. The frame, forks, engine, and much of the styling were all new. Styling at Harley-Davidson reached new heights during this era. The “Comet” tank emblem was used from 1936 to 1939. There were the new oval section Springer front fork tubes, a new style and design for the exhaust system, and a tank-mounted speedometer. The 1936 EL could even be purchased in several two-tone paint jobs.

In 1937, Harley released a new generation of side-valve motors. These U series motors were a dry-sump oil design. Most parts were made in common with the Model E 61ci OHV motor from a year earlier. However, this motor was completely revised with many updates that separated it from the earlier V motor. Changes included new cases, cylinders, and bearings throughout the lower end.

The UL was designated as the Special Sport Solo. The higher-compression motor was available in 74 or 80 cubic-inch size. While technology for the side valve twin was trickled down from the more advanced OHV motorcycle, Harley-Davidson produced three times as many side-valve motorcycles than the OHV.

The UL production in 1937 was 2861 units. These motorcycles sold for $395. Knucklehead motors are highly sought after by collectors. The 61 and 74 cubic-inch overhead valve V-Twins were produced for 12 model years (1936 through 1947).

**More important than classic Harley-Davidsons: Thank you to Jerry Buffington for bringing his HD to this vintage motorcycle show and for his service to our country. You are the reason we can enjoy such a beautiful day & event!!**
