The listed tank capacity is 4.09 US gal (15.5 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 25.5 lb (11.5 kg). That is an estimate for fuel mass, not an official Kawasaki curb-weight calculation.
How heavy is the Kawasaki ER-4n with an average-size rider?
A 180 lb rider brings the simple bike-plus-rider total to roughly 618.7 lb (280.6 kg) using the representative wet/running figure. Gear and luggage would add more.

Will the Kawasaki ER-4n feel heavy at low speed?
It is most likely to feel heavy while stopped, backing up or on a slope rather than once settled at normal riding speed. Seat height and center of gravity matter a lot.
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.
