My not-so-humble opinion? Nobody knows squat! Not dealers and not anybody working for Yamaha even. Yamaha, like other Japanese OEMs is very secretive with their future plans and products. And the VERY few people who may know something want to keep their great job and keep their mouth shut! So don't believe anything a dealer or even a Yamaha sales rep will tell you. It is just their guess! The VERY smart feller I know not too long ago told me that Japan doesn't tell Yamaha USA shit about future FJR plans. Yamaha USA doesn't know if it coming or not until the shortly before it is publicly announced in late fall every year. He did say that he is confident there will be no FJR replacement after it is discontinued here as Yamaha seems to be putting effort and $$$ into the lightweight sport-tourer class, a-la the Tracer 9 GT.
My own personal SWAG? The last year that the FJR is available here we will see the Black/Gold edition that they have offered in the only markets they have discontinued sales - Europe and Japan. As for when that happens. My guess is 2023 or 2024. That opinion is worth exactly what you paid for it.
As for the originally referenced article? It was terrible. Short on facts and long on guesses. Irresponsible journalism.
