The Genuine Buddy 125 driven pulley diagram shows the complete rear CVT transmission assembly, including the clutch assembly, clutch bell, drive plate, pressure plate, contra spring, movable drive face, fixed drive face, ramp plate, variator interface components, torque spring system, and related bearings and fasteners. This diagram is used to identify OEM replacement parts for drivetrain service, clutch repairs, belt drive maintenance, and CVT performance tuning. The driven pulley controls how power is transferred from the engine to the rear wheel by managing belt tension and clutch engagement. Common repairs include replacing worn clutch shoes that cause slipping or poor acceleration, servicing a weak contra spring that affects throttle response and top speed, replacing a glazed clutch bell that causes shuddering, and rebuilding the CVT assembly to restore smooth engagement and consistent power delivery.
