THey were only sold in the US in 82 and 83. The 83 had a larger fairing, air assist forks, improved carbs, dual f discs, and a few other tweaks. My last one (the red one pictured above) was an 82 but with lots of mods from an 83, clipons, gusseted frame and a final drive gear from a Euro bie with taller ratio.
It was a 70 deg counterbalanced V, DOHC, 8V, shaft drive, way ahead of it's time and if not for a shitty stator design (fried them like eggs) it would have sold better (that, and it was way overpriced, a common gaff of Yamaha with new model intros).
The motor was designed by the same dude as the Vmax/Venture V-four, and is basically half of a V-max.
It could really be made to scream, was comfortable and had good range. It was Yamaha's first street bike with a monoshock rearend.
