I know this is an older thread but my answer may help someone.
When I ordered mine I didn’t want the Grey or Black that the dealer had there and told him I only wanted Blue. He checked stock online with Yamaha and I was told it would take roughly 2-3 weeks for it to arrive in the UK from Europe once ordered. In reality it was there in less than 2 weeks. The colour availability thing though, he recked that Yamaha only had a small number of blue ones left and owning to the fact we were only 3 months from the end of the year and the 2019 colours being released it could have been different.
