Kawasaki W1 weight overview
This is neither unusually light nor extremely heavy. For most riders the practical weight question is more about seat height, center of mass and low-speed balance than the scale number alone. The comparison uses dry weight because a usable wet/running figure was not supplied, so the actual ready-to-ride motorcycle will be heavier.

Kawasaki W1 weight FAQ
How heavy is the Kawasaki W1?
Listed dry weight is 399 lb (181 kg). Because no usable wet/running figure was supplied, treat that as a lower starting point rather than the exact on-road weight.
Is the Kawasaki W1 heavy compared with other Kawasaki allround models?
It sits fairly close to the middle of the category. Its representative dry weight is around the 54th percentile among 12 compatible Kawasaki allround models.
Does the Kawasaki W1 weight change by model year?
Not in the usable weight data on this page. Across the covered 1965-1969 years, the supplied weight figure remains the same where comparable values are available.
How much does the Kawasaki W1 fuel weigh?
The listed tank capacity is 3.96 US gal (15 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 24.6 lb (11.2 kg). That is an estimate for fuel mass, not an official Kawasaki curb-weight calculation.
How heavy is the Kawasaki W1 with an average-size rider?
A 180 lb rider brings the simple bike-plus-rider total to roughly 579 lb (262.6 kg) using the representative dry figure. Gear and luggage would add more.
How much horsepower does the Kawasaki W1 have per 100 lb?
Where compatible power and weight figures are available, it works out to 13.11 hp per 100 lb.
Can I treat the Kawasaki W1 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 423.7 lb (192.2 kg), and oil/coolant or definition differences may add more.
What does the Kawasaki W1 weigh with a full tank?
Using the listed dry weight plus the calculated fuel mass, the estimated weight with a full tank is 423.7 lb (192.2 kg). That still may not equal official curb weight because dry-weight definitions can exclude other fluids or equipment.
What is the Kawasaki W1 torque per 100 lb of bike weight?
The calculated torque-to-weight range is 10.15 lb-ft per 100 lb to 10.17 lb-ft per 100 lb. It is useful for comparing bikes with very different overall weights.
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 Kawasaki website.
