Yamaha Motor Co., Ltd. 5ST-E6611-01-00 Clutch Housing

The Yamaha 5ST-E6611-01-00 Clutch Housing is a hardened steel outer clutch bell that houses the clutch assembly and transfers rotational force to the drivetrain in centrifugal clutch systems. It is commonly used in Yamaha scooters such as the Vino and other small-displacement models, where it engages with the clutch shoes during acceleration to enable smooth takeoffs. Weighing about 0.9 kg and designed as a direct OEM replacement, it is manufactured for Yamaha scooter applications in both OEM and aftermarket options and features a hardened steel drum designed for heat resistance in friction contact.
