Harley started a revolution in 1936 with the OHV Knucklehead that is still
going strong today. Arguably the best looking motor ever to come out of
Milwaukee, it still stops the informed dead in their tracks on the street or at
the shows.
Now, with technical innovations, advances in materials, and super-accurate
machine tolerances; big inch, reliable Knuckle-style engines are a reality at
Accurate Engineering. We're not talking trailer queens here, these babies run
and they run strong!
Knucklehead engines are available as Special Order Only.
