Buy a new motorcycle with a long service life – risks?

Hello together, I might buy a Husqvarna Svartpilen 125. Since the parts are shopkeepers, it could be that the machines are already 1 year at the dealer on the sales floor. Could there be problems there? I have read that there can be rust in the tank and unround tires for example. Is it even normal that new motorcycles are standing outside and pushed in again every night? For example, a screw had already started blue on one model. I also used to use a screw. After 12 months of service, cars can no longer be sold as new cars. Does this also apply to motorcycles? Thank you in advance!
