Kawasaki Z1-B weight overview
This is firmly on the heavier side. The real penalty is not necessarily normal riding; it is low-speed work, awkward parking and moving the bike around manually. 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 Z1-B weight FAQ
How heavy is the Kawasaki Z1-B?
Listed dry weight is 513.7 lb (233 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 Z1-B heavy compared with other Kawasaki naked bikes?
Relatively speaking, it is on the heavier side. The model sits near the 83rd weight percentile in its Kawasaki category, so it is heavier than most of the compatible comparison set.
How much does the Kawasaki Z1-B fuel weigh?
The listed tank capacity is 4.76 US gal (18 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 29.6 lb (13.4 kg). That is an estimate for fuel mass, not an official Kawasaki curb-weight calculation.
How heavy is the Kawasaki Z1-B with an average-size rider?
A 180 lb rider brings the simple bike-plus-rider total to roughly 693.7 lb (314.6 kg) using the representative dry figure. Gear and luggage would add more.
Can I treat the Kawasaki Z1-B 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 543.2 lb (246.4 kg), and oil/coolant or definition differences may add more.
What is the Kawasaki Z1-B full-tank weight estimate?
Based on the available dry-weight and tank-capacity data, a full-tank estimate is 543.2 lb (246.4 kg). Oil, coolant and market-specific equipment can still make actual ready-to-ride weight different.
How much torque does the Kawasaki Z1-B have per 100 lb?
The calculated torque-to-weight range is 10.32 lb-ft per 100 lb. It is useful for comparing bikes with very different overall weights.
What is the Kawasaki Z1-B displacement per pound?
Engine displacement relative to bike weight is 1.76 cc per lb. It can help compare motorcycles from very different displacement classes without relying on cc alone.
What is the Kawasaki Z1-B weight difference versus the category median?
The model sits about 60.6 lb (27.5 kg) heavier than the compatible median Kawasaki naked bike weight used on this page.
Motorcycle specifications can vary by model year, market, equipment and the exact dry/curb-weight definition.
