Are you talking about the TS-mark? You get it when your bike is registered and inspected. If your bike is registered and inspected the inspection fee covers the TS-Mark, you don't need anything else.
I don't know who sold you that crap but it sounds like you got scammed.
You mean to cover the inspection fee? The inspection sticker doesn't have an annual fee.
You don't need anything else other than the inspection sticker.
