A drive assembly for a two-wheeled vehicle, wherein a closed chain is guided around a drive pinion and a sprocket for output. The chain is formed by pins, on each a bush rotatable about the center longitudinal axis of the pin, a roller provided on each bushing, for rotation around the bushing and has play, and the pins being connected to each other at two opposite ends by means of plates. The outer surface of the bushings and the rollers is coated with pure ta-C, having no further chemical elements except for unavoidable trace elements resulting from production in a PVD method. An Ra roughness between 0.03 μm and 0.2 μm and/or an Rz roughness between 0.3 μm and 2 μm is adhered to the surface of the coatings. The surfaces of the pinion and the sprocket in contact with the rollers do not have a coating of diamond-like carbon.
