When it comes to vintage machines from the Milwaukee manufacturer, those powered by the “Knucklehead” engine are particularly desirable. So-named for the fist-like shape of its valve covers, this 45-degree, overhead-valve engine was built from 1936 through 1947.

This 1947 EL, powered by a 48-horsepower, 61-cubic-inch air-cooled V-twin, comes from the last year of Knucklehead production. The most developed and refined iteration of the characterful powerplant, it would be replaced by the so-called “Panhead” for 1948.

This EL is paired with a genuine, period-correct Harley-Davidson sidecar numbered 47LE1374. Appropriate for a sidecar rig, the motorcycle is equipped with a three-speed-plus-reverse gearbox with a tank shifter. Harley-Davidson-manufactured sidecars sported many details that perfectly complemented their corresponding bike, including decorative fender accents and new-for-1947 “tombstone” taillights. An upright windshield and a covered rear-mounted spare wheel makes this an ideal companion for long-distance touring.

This motorcycle/sidecar pair was restored under prior ownership in a subtle and attractive two-tone cream and copper, with a black leather seat and sidecar fairing providing well-chosen contrast.
