80ci Shovelhead Power

At the heart of the 1981 FXS is the 80-cubic-inch Shovelhead V-twin. Reference specifications list the engine at 1,337cc with a 7.4:1 compression ratio and a four-speed transmission.

For collectors, the appeal isn’t simply the displacement. The Shovelhead engine is an important part of Harley-Davidson history and gives the FXS its distinctive appearance, sound, and mechanical personality.

When purchasing a used or restored FXS, buyers should pay close attention to engine condition, oil leaks, compression, starting behavior, carburetion, ignition, and evidence of previous engine work.

Classic FX Low Rider Styling

The Low Rider’s appeal comes from its proportions as much as its engine. The relatively low seat height, FX chassis, and combination of 19-inch front and 16-inch rear wheels create the classic stance associated with the model.

Originality can also have a major influence on the desirability of a vintage FXS. Buyers looking for a collectible example should inspect the frame, engine numbers, paint, wheels, controls, exhaust, instrumentation, and other components for evidence of modifications or replacement parts.

What to Check Before Buying a 1981 FXS

If you’re shopping for a 1981 Harley Davidson FXS Low Rider, condition is more important than appearance alone. A thorough inspection can help distinguish between a complete restoration candidate and a motorcycle requiring extensive mechanical work.

Before purchasing, consider checking:

Engine and Transmission

Inspect the Shovelhead engine for leaks, unusual noises, smoke, and signs of previous repairs. Confirm that all four gears engage correctly and that the clutch operates properly.

Frame and Chassis

Look carefully for cracks, repairs, corrosion, or modifications to the frame. Check steering-head and swingarm areas for wear or damage.

Electrical System

A vintage Harley may have received electrical modifications during its lifetime. Inspect the wiring, ignition, charging system, switches, lights, and battery installation.

Wheels, Tires, and Brakes

Check wheel condition, tire age, spokes or cast-wheel condition, wheel bearings, brake discs, calipers, and master cylinders. Reference fitment data lists 19-inch front and 16-inch rear wheel applications for the 1981 FXS.

Originality

If you’re buying the motorcycle as a collector piece, compare the bike against period documentation and examine whether major components are original, restored, or aftermarket.
