Fitment FAQ
Will this part fit my specific model and year?
This replacement part is intended for GY6 139QMB 50cc–200cc Scooter ATV. Key physical/spec details from the product data include Mounting Hole Distance (Length): 58mm / 2.28", Mounting Hole Distance (Width): 31mm / 1.22", 50cc. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. If your original part has a stamped OEM or manufacturer number, match that number first before ordering. For this replacement part, also compare the OEM number, dimensions, connector or mounting style, engine/model year, and product photos. This is especially important for GY6 GY6 models because similar model names can use different parts by year or trim.
What models or situations does this part not fit?
Do not order this replacement part for machines outside the listed compatibility, or for units with different OEM numbers, dimensions, mounting points, connectors, or year-specific configurations. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the OEM number, dimensions, connector or mounting style, engine/model year, and product photos. Recheck listed specs such as Mounting Hole Distance (Length): 58mm / 2.28", Mounting Hole Distance (Width): 31mm / 1.22", 50cc. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
For the price, I'm definitely not going to complain. Especially on a used scooter. We live in an odd little city where I swear there's more scooters than cars. Anyway, this is a fairly simple switch so not a whole lot to say. I'm just glad it works! Regarding price, this is the first time I've replaced a scooter ignition. I have on cars, trucks, etc... and even dirtbikes and atvs all for a good bit more money so I'd say this felt fair. It fits mostly well but there's just a little looseness. My scooter is some really rigged together thing though. I wouldn't think too much of it.
