  • Damped motorcycle primary drive sprocket system with dampers
    Patent number: 10927939
    Abstract: A damped primary drive sprocket system is provided that may be directly driven by a motorcycle engine and may be arranged in a primary drive connecting the motorcycle engine to a motorcycle transmission. The damped primary drive sprocket system may include damper segments such as discrete isolator bushings arranged in leading and trailing slot chambers, on opposite sides of a lug within a slot of a coupling system that connects a hub to a sprocket within the damped primary drive sprocket system. The slot chambers may be circular in cross-sectional perimeter shape so and the isolator bushings may be cylindrical and fit snugly in the slot chambers in a manner that damps slight rotational clocking movements of the hub and sprocket with respect to each other during firing pulses of the motorcycle engine.
