Kawasaki KH 400 weight FAQ
What is the Kawasaki KH 400 wet weight?
The supplied wet/running weight is 390.2 lb (177 kg) across the model years covered here. That figure is the most useful available number for real-world handling because operating fluids and fuel are included.
Which Kawasaki KH 400 years have different weight specs?
No clear weight change appears in the usable model-year data. Other specifications may still differ by year.
How much does a full tank add to the Kawasaki KH 400?
Based on the supplied 3.7 US gal (14 L) to 4.23 US gal (16 L) tank capacity, the gasoline itself weighs about 23 lb (10.4 kg) to 26.3 lb (11.9 kg) when full. On models with a wet/running weight, that fuel mass is already included in the listed ready-to-ride figure.

Using the model’s representative wet/running weight and a 180 lb rider, the combined bike-and-rider mass is about 570.2 lb (258.6 kg) before riding gear, luggage or a passenger.
How much of the Kawasaki KH 400 total weight comes from fuel?
The calculated full-tank fuel mass is about 5.9% to 6.7% of the listed motorcycle weight. Because the available basis is wet/running weight, that fuel is already included in the ready-to-ride figure.
What is the Kawasaki KH 400 engine-size-to-weight ratio?
The available figures work out to 1.03 cc per lb. This is not a performance rating, but it is a useful way to compare engine size against total motorcycle mass.
Where will I notice the Kawasaki KH 400 weight most?
Expect the weight to matter more off the throttle than at speed: garage movement, uneven footing and parking angle are the practical situations to think about.
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.
