As grey as Scar Fell in the rain.
I read the all EU laws that I could find on the net last year. It was all about selling in the EU, i.e. not legal for sale with in the UK (unless commercial or racing as discussed).
So nothing wrong with selling outside the EU.
I emailed (so I had it in writing) customs at the port where said motor would arrive at. The response was; phone us and pay the duty and the motor would be released for collection by my courier.
So as long as the duties were paid customs had no problem with the "import". As said, the EU law only applies to the sale, nothing about import or use in the EU that I could find.
