In combination with a wheeled vehicle of the type having a power output shaft driven by an engine through a power transmission system, a driven rear wheel journaled thereon and having a ring sprocket secured thereto, and an endless chain drivingly engaged with the ring sprocket, an improved drive sprocket comprising:

• a metallic hub portion rigidly securable to the power output shaft for coaxial rotation therewith, said hub portion having a plurality of T-shaped lands and T-shaped grooves formed on the outer periphery thereof coaxial with the axis of rotation;
• and
• a ring portion secured to the outer periphery of said metallic hub, said ring portion being formed of a synthetic resin material having an aperture formed therein with a plurality of T-shaped lands and T-shaped grooves formed on the inner periphery thereof sized and shaped for closed sliding coaxial mutual engagement with the corresponding T-shaped grooves and T-shaped lands of said hub portion, and having teeth formed about the outer periphery thereof drivingly engaging the endless chain.
