Harley-Davidson Hummer weight overview
This sits at the very light end of motorcycle mass, which is especially useful when the bike has to be moved around by hand or held on uneven ground. The comparison uses dry weight because a usable wet/running figure was not supplied, so the actual ready-to-ride motorcycle will be heavier.

Harley-Davidson Hummer weight FAQ
How heavy is the Harley-Davidson Hummer?
Listed dry weight is 170 lb (77.1 kg). Because no usable wet/running figure was supplied, treat that as a lower starting point rather than the exact on-road weight.
Does the Harley-Davidson Hummer weight change by model year?
Not in the usable weight data on this page. Across the covered 1955-1959 years, the supplied weight figure remains the same where comparable values are available.
How much does the Harley-Davidson Hummer fuel weigh?
The listed tank capacity is 1.74 US gal (6.6 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 10.8 lb (4.9 kg). That is an estimate for fuel mass, not an official Harley-Davidson curb-weight calculation.
How heavy is the Harley-Davidson Hummer with an average-size rider?
A 180 lb rider brings the simple bike-plus-rider total to roughly 350 lb (158.7 kg) using the representative dry figure. Gear and luggage would add more.
Can I treat the Harley-Davidson Hummer dry weight as curb weight?
No. The usable figure is dry weight, so it excludes at least some operating fluids. Dry weight plus the estimated full fuel load is about 180.8 lb (82 kg), and oil/coolant or definition differences may add more.
What is the Harley-Davidson Hummer displacement per pound?
Engine displacement relative to bike weight is 0.74 cc per lb. It can help compare motorcycles from very different displacement classes without relying on cc alone.
Will the Harley-Davidson Hummer feel heavy at low speed?
Its low mass should make hand-moving and parking easier than on most full-size road motorcycles. Seat height and center of mass can still change how manageable it feels.
Motorcycle specifications can vary by model year, market, equipment and the exact dry/curb-weight definition. Calculated fuel-weight and ratio figures on this page are estimates derived from the supplied specifications. Confirm critical figures in the owner’s manual or on the official Harley-Davidson website.
