For the vintage enthusiast, S&S Cycle is showing their new 93 cubic inches KN-Series engine now in production. It is very close in appearance to the Harley Knucklehead but is offering more of today’s features in terms of power and improved reliability.
Aside from the much larger 93″ displacement, the main improvement in design is the 1958-1965 style flywheel assembly, which uses a splined sprocket shaft and Timken® sprocket shaft bearing. Although this necessitates the use of a 1955-1964 style inner tin primary cover and primary chain sprocket, the increased flywheel stability, strength, and power handling capacity are worth a slight departure from stock.
The initial KN93 offering is a standard compression 93 inch engine with authentic generator style crankcases for 1936-1947 Harley-Davidson® OHV big twin chassis. The KN-Series engine comes completely assembled and ready to run with a preset S&S Super Stock™ electronic ignition system and Super E carburetor and is sold with a 12 month warranty. MSRP $8575.
