1930 Henderson KJ "Streamline." The Vero Beach Museum of Art has an exhibit called "Rolling Sculpture" featuring cars of the Art Deco period. The cars are gorgeous works of art but there also are two motorcycles. Just before the stock market crashed in 1929, four motorcycle manufacturers competed: Harley-Davison in Milwaukee, Indian in Springfield MA, Henderson & Excelsior in Chicago and Ace 4 in Philadelphia. It was "The Golden Age of the Fours." The 1929 "Streamline," seen here, could attain 100 mph based on a 1200-cc 40-bhp in-line 4-cylinder engine, a 5 main bearing crankshaft and a downdraft carburetor. O. Ray Courtney used it as a platform in 1930 to build a radically streamlined body with a front like a Chrysler Airflow and a rear like an Auburn boat-tailed Speedster. Only one was ever built. This motorcycle reminded me of the movie "The Fastest Indian" (2006) which is presently on Netflix. The movie deals with New Zealander Burt Monro who customized an Indian motorcycle and in 1967 took it to the Bonneville salt flats in Utah to set a world speed record that still has not been broken. It's a great flick, and his Indian looked a bit like this "Streamline."
That is a gorgeous bike! Love the curves, beautifully captured.
