2027 KZ Sportster X3411X

KZ lists the 2027 Sportster X 3411X at 13,560 lb unloaded (UVW), with a GVWR of 16,000 lb, a cargo carrying capacity of 2,440 lb and a dry hitch weight of 2,520 lb. Its UVW plus its cargo capacity comes to exactly its GVWR.

It is 39' 11" long and 13' 5" high with the air conditioner, with 100 gal fresh, 50 gal grey and 88 gal black tanks. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank uses roughly 830 lb of the cargo capacity before anything else is loaded.

Among the 7 Sportster X floorplans KZ lists for 2027 with a published weight, it is number 6 by unloaded weight, in a range from 7,080 lb (20X) to 14,620 lb (3914X). Every figure in that comparison is KZ’s, for the same model year.

Every number on this page was read on 5 Nov 2026 from KZ’s own floorplan page for the Sportster X 3411X, whose floorplan drawing KZ labels 2027. KZ notes that its UVW reflects a rolling average for the model and that your trailer will vary with optional equipment.
