Fitment FAQ
Will this part fit my specific model and year?
This ignition switch is listed for selected GY6 49cc/50cc Chinese 4-stroke scooters and mopeds, including Jonway 50QT-21.
Fitment requires a compatible 4-pin connector, pin layout, lock-body design, mounting configuration, and electrical function.
Do I need to match the OEM part number?
No OEM part number is provided for this aftermarket ignition switch.
Instead, compare:
4-pin connector
Connector shape
Pin layout
Wiring configuration
Lock-body shape
Mounting points
Key-switch positions
Original switch appearance
A matching 4-pin connector alone does not guarantee electrical compatibility.
What models or situations does this part not fit?
The original product information specifically excludes:
QT50-21 Scooter
Riya 2017 Scooter
Also, do not assume compatibility with:
Every GY6 50cc scooter
Every Chinese 49cc/50cc moped
2-stroke scooter applications
Switches using a different connector
4-pin switches with a different pinout
Lock assemblies with different mounting points or body dimensions
What should I check before ordering?
Confirm:
GY6 49cc/50cc 4-stroke application
Exact scooter make and model
4-pin connector
Connector shape
Pin positions
Wiring configuration
Lock-body design
Mounting points
Key-switch positions
Original ignition-switch appearance
For Jonway applications, verify the model is specifically 50QT-21, not QT50-21.
