The items of riding horse harness (bits with psalia, stirrups, buckles, decorations of bridles) are analyzed in the article on the basis of the materials from the Chulkovo (Murom) burial ground site of the 8^th –10^th centuries, located on right bank of the Oka river. It has been established that the use of horse harness items by the Muroma culture population, which had left the Chulkovo burial ground, is in full correspondence with the general traditions of the Finno-Ugric peoples of the Volga river region characteristic of the 8^th –10^th centuries. The shapes of the bits correspond to both the steppe (bits with S-shaped and straight psalia) and the local traditions (bits with two and three moving rings). A tendency to uniformity is observed in the tradition of stirrups production. The main differences of the Muroma burial grounds from the neighboring Mordovian ones consist in the presence of horse burials (not known among the Mordovians), and, on the other hand, in a practically complete lack of horse harness in the funeral set of human burials. It can be assumed that the importance of cavalry with the Muromа was lower than with the Mordovians who were living next to the steppe world.
