Black/Yellow LK-120 I got my license and bought a motorcycle after being encouraged by a friend, but it didn't suit me and I sold it after a month. This is the lock I was using at the time. Therefore, the usage period was short and the condition is good, I think it's clean. I think the battery is depleted, so replacement is recommended. (It worked fine during the operation check before listing). It's a type that switches the alarm on and off by changing the front and back of the U-shaped part. There is a screw on the bottom that can be removed to replace the battery. Please purchase only if you understand that this is a used item.
