Bison, buffalo, taurine antelope, and saola are bovines, too. Banteng are the fourth largest extant wild oxen after gaur, longhorns, and white park oxen.
Biggest bovine is the Asiatic Water buffalo of Assam & Bhutan which can grow to about 1200 kg in the wild for a big bull. The Indian gaur may get to similar weights but the average is just a bit smaller. The banteng is definitely smaller than these two wild bovines. I am not sure if the banteng is bigger than the African cape buffalo and the American Bison.
