This is the genuine Yamaha factory-original seat damper (3L8-24724-M0) specifically designed for the Yamaha QT50 "Yamahopper." This rubber suction-cup style damper acts as a cushion between the seat base and the frame, preventing vibration, rattling, and paint damage to the rear bodywork. If you are restoring a QT50, using genuine OEM rubber components is essential to ensure the seat sits at the correct height and remains secure during operation.
4. Vehicle Compatibility
| Make | Model Range | Application |
| Yamaha | QT50 Yamahopper (All Years) | Seat Mounting |
| Yamaha | Various 1980s Moped/Scooter Models | Seat Cushioning |
Note: While primarily identified with the QT50 series, this part is used as a universal seat bumper on various small-displacement Yamaha mopeds and scooters of that era. Always confirm your seat base hole diameter.
5. Fitment Details
This is a direct OEM replacement. To install, clean the mounting hole on the seat base to ensure it is free of dirt and old rubber debris. Because these parts are small and designed for a friction fit, a drop of water or a mild silicone spray can make installation significantly easier. Once inserted, the "suction cup" design provides a secure seat-to-frame interface. Given that these rubbers are often missing or dry-rotted on survivor mopeds, replacing them provides an immediate improvement in seat stability and overall machine presentation.
