Harley-Davidson, X-90, Shortster, Aermacchi, Mini Bike, Collection Ready

Feast your eyes on this 1973 Harley-Davidson X90 “Shortster”, a rare gem built in September 1972 and destined to be a '73 model. Bearing the authentic VIN X90 2013993H3, it stands as an early, honest piece of Harley history—compact, quirky, and brimming with character.

Refurbished with care, this little marvel features a refreshed 90cc two-stroke with a smooth 4-speed transmission, newly coated frame, a gleaming black tank finished with tasteful AMF stripe decals, and zinc- and chrome-plated trim that catches the light just right. The original 20 mm Dell'Orto carburetor, oil injection, drop-down cross-braced handlebars, 10″ slotted steel wheels, and full suspension preserve its period-correct charm.

The engine rebuild was entrusted to Sonny's Motorcycle Repair & Restorations in Lowell, Massachusetts, a respected name in vintage bike restoration. It now runs strong and, according to enthusiasts, will reach speeds of 50+ mph with ease, outpacing bikes like the Honda Trail and proving that this small Harley packs surprising punch.

The Harley-Davidson 80-mph speedometer shows just a handful of miles since completion, signaling that this Shortster is ride-ready and fun to pilot.

Included with the bike are thoughtful extras like an owner's manual, period ads, and a sales brochure—giving you not just a motorcycle, but a piece of history. Offered with a clean title and transparent terms, it's a standout opportunity in the X90 world.

Whether you're hunting for a collector's conversation piece, nostalgic weekend cruiser, or just something irresistibly unique, this Shortster checks all the boxes and then some.
