Randyyo is correct, what you are referring to as end weights are not weights. They are plastics bar end plugs that look like weights but weight less then an ounce each.
As far as the grips go they are more comfortable than the factory grips but may not work well if you have small hands. Te diameter of the grips is fairly large and people with small hands (or short fingers) may have issues reaching the brake/clutch levers.
