REAR HUB BUSHING TMX / CG / RUSI STEEL BUSHING RUBBER BUSHING HUB BUSHING MOTORCYCLE PARTS MODEL

REAR HUB BUSHING TMX / CG / RUSIA rear hub bushing in a motorcycle, often referred to in the context of the rear wheel as a cush drive rubber or damper rubber, is a crucial drivetrain and suspension component designed to sit between the rear sprocket hub and the wheel hub. Its primary purpose is to absorb shock and reduce vibration, ensuring a smoother ride and protecting expensive components from damage caused by rapid torque changes.Purpose of Rear Hub BushingsShock Absorption & Cushioning: The bushing cushions the force of the engine trying to turn the rear wheel, absorbing the sudden jolts and "jerkiness" during acceleration, deceleration, and gear shifts.Vibration Damping: It acts as a dampener to prevent engine vibrations from being transmitted directly to the frame and rider, reducing fatigue.Drivetrain Protection: By absorbing torque pulses, it prevents "back-torque" or "torque shock" from damaging the chain, sprockets, and gearbox.Alignment & Stability: It keeps the rear sprocket and wheel hub properly aligned, which prevents "squirrely" behavior (unstable handling) at high speeds.Functions of Rear Hub BushingsFriction Reduction: It reduces metal-to-metal contact between the sprocket flange and the wheel hub, minimizing wear and heat buildup.Torsional Flexibility: The rubber allows slight, controlled movement ("lash") to smooth out power delivery, enhancing traction and preventing wheel hop.Noise Reduction: It acts as an acoustic barrier, reducing the clatter of the drivetrain.
