Honda CB400A 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.

Honda CB400A weight FAQ
How heavy is the Honda CB400A?
Listed dry weight is 429.9 lb (195 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 Honda CB400A heavy compared with other Honda naked bikes?
Relatively speaking, it is on the heavier side. The model sits near the 75th weight percentile in its Honda category, so it is heavier than most of the compatible comparison set.
Does the Honda CB400A weight change by model year?
Not in the usable weight data on this page. Across the covered 2016-2017 years, the supplied weight figure remains the same where comparable values are available.
How much does the Honda CB400A 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 Honda curb-weight calculation.
How heavy is the Honda CB400A with an average-size rider?
A 180 lb rider brings the simple bike-plus-rider total to roughly 609.9 lb (276.6 kg) using the representative dry figure. Gear and luggage would add more.
Can I treat the Honda CB400A 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 459.5 lb (208.4 kg), and oil/coolant or definition differences may add more.
What does the Honda CB400A weigh with a full tank?
Based on the available dry-weight and tank-capacity data, a full-tank estimate is 459.5 lb (208.4 kg). Oil, coolant and market-specific equipment can still make actual ready-to-ride weight different.
How much torque does the Honda CB400A have per 100 lb?
The calculated torque-to-weight range is 6.52 lb-ft per 100 lb. It is useful for comparing bikes with very different overall weights.
What is the Honda CB400A displacement per pound?
Engine displacement relative to bike weight is 0.93 cc per lb. It can help compare motorcycles from very different displacement classes without relying on cc alone.
Motorcycle specifications can vary by model year, market, equipment and the exact dry/curb-weight definition.
