Kymco 12-16 inch 50cc 4-stroke lock key variator/starting sprocket

To dismantle the variator of your scooter, use a variator lock key.

Dismantling the variator with a locking key

A varioblocking key is easy to install. Once the kickstart lid has been dismantled, you will see the variator. By installing the lock key, the vario is blocked and the crankshaft nut can be loosened! Once this nut is loose, the variator can be dismantled. A variator lock key is a simple, safe and indispensable tool for blocking and then dismantling the variator when no compressor/air tools are present. This key fits any Kymco 50cc 4-stroke scooter with a 12.14 or 16-inch rear wheel. You can find the size of the rear wheel on the side (cheek) of the rear tire. This lock key is only suitable for Kymco and is therefore not suitable for other scooters with a GY6 engine (like most Chinese scooters). If in doubt, please contact customer service via chat or contact form. We are happy to advise you on the type of engine block of your scooter and the corresponding lock key.
