The variator on those can be stubborn to hold still. Before you buy anything. Do you have a photo of what you're working with. Sometimes the OEM tool shows up cheap on the used sites and saves you from guessing on fitment. If you're set on an aftermarket locking tool just make sure you verify the bolt diameter and the exact variator cup design on yours first. Plenty of people end up with something that's close but not quite right for a 50cc Kymco.
