the 3rd basic type of V-Twin engine called the Knucklehead to replace
the top-of-the-line Flathead VL model. It was named "knucklehead"
because of the unique shape of the rocker boxes. Originally called
"OHV's" the term "Knucklehead"spawned from the 1960's California
chopper culture. A knucklehead engine has round knobs on the cover
resembling knuckles. The knuckle head was replaced in 1948 by the
ultimate Frankenstein Engine in our option would be a Knuckle-Pan-Head, or
Pan-Knuckle, or Pan-Knuckle Pan, whatever you want to call it...its
cool, intriguing, and the shit! Visually its the best of both worlds
for any Harley enthusiast...would it spew oil?...it sure would and you
would ride it with full honors....so we made a tee to honor this
