I don't think it is do-able.

First, you put yourself in a undesirable position by selling something that you imported on the understanding that it was a temporary import of a tourist vehicle.

Second, the buyer would have difficulty getting the motorcycle to pass a technical inspection because the lighting and emissions regulations in Europe are not the same as those in Canada, and a search of the VIN of the vehicle by the licensing authority would reveal that the bike was not manufactured for use in Europe.

I speak from experience here - I frequently flew my Canadian-plated motorcycle back and forth to Europe, and in the early 2000s, I made inquiries about re-plating it in Europe, or selling it in Europe, this because I was working in Europe for several years. All the answers came back "no" or "not possible".

I once loaned my moto to a European resident friend for a weekend - he was stopped by police, and wound up having to pay a €2,000 fine related to customs & import violations. The rationale behind the fine was that I (the Canadian tourist) had temporarily imported the motorcycle tax-free for touristic purposes, therefore my friend (the European resident) was possessing and using something in contravention of the laws governing temporary import of motor vehicles for touristic purposes.
