The 1927Harley - DavidsonBA motorcycle was an attempt by the growing Wisconsin society to pop the question an economical undivided - piston chamber model that still retain some of the fabled Harley power .
Though stinting to buy and run , Harley ’s 21 - cubic - column inch single never sell particularly well during its ten - year production running game .
However , competition versions , known as " pea plant - shooters " due to the sound of their exhaust note , lay claim many victories at the hand of Joe Petrali during the same flow .
Two versions of the single were offered : a monotonous - fountainhead with eighthorsepowerand an overhead - valve version producing twelve HP – an telling 50 - percent increase .
Yet the flathead sold well due to its lower cost and easy maintenance . Both could be fitted with galvanic inflammation like the flathead designate .
America ’s taste for freehanded , powerful Gemini led to the death of these exclusive - piston chamber models in the mid 1930s .
Harley continued for a time with a larger 30.5 - cubic - in single and made several late attempts at sell unmarried - cylinder machines , but it was always V - twins for which the company was well known .
