Jack Tracey, life-long member and President of the world's oldest motorcycle club, the Yonkers Motorcycle Club and owner of the Harley-Davidson dealership in Yonkers (NY) asked Stelling & Helling to develop handlebars taller than the original "comfortable" Speedster bars. S&H came up with these ones with horn and dimmer switch mount holes on the left side and a shortened grip area for use with the short Hellings type spirals. These bars are made for in-line Springer forks with the outer holes measuring 4 3/4" (120.7mm) center to center and come complete with parkerized end plugs. Order pinch bolts and two short spirals separately. Grips must be cut to length for this installation. "In-line" forks were originally made for 1936-1940 Big Twin with 28° frame neck, 1941-1945 Big Twin with 29° frame neck, 1929-1957 45CI Solo and 1937-1957 Servicar. Offset forks were stock on 1946-1948 EL and FL Big Twin with the 30° frame neck as well as most reproduction rigid frames with stock 30° neck.
