Your question isn't clear to me . Are you referring to an extra sprocket? If so
maybe to drive a large auxiliary generator to charge those extra batteries. Is
that front stand the inventor's idea or a period accessory ?

Picture and caption from the Los Angeles Herald-Examiner newspaper; A police
radio motorcycle, believed to be the first without an operator in a side-car, were
cruising Culver City as a new weapon of crime prevention. Photo shows Officer L.
O. Lindsay with the compact motorcycle radio equipment which he has invented.
Photo dated: January 16, 1932.
Bike has several modifications,including the cut off chain guard and drive
output sprocket,any ideas on what it's for?
