I have an '87 FZR1000 I bought from a friend, barely 1 yr old. I prefer the riding position to the YZF1000's. I don't ride it much. I bought my VMax to have as an alternative to the FZR1000, 29 years ago. The difference is like my since-sold '80 Z-28 back in the 1980's, compared to my S2000 AP-1. The handling is on another level, though the FZR1000 is older than the VMax. Sportbike vs. cruiser. The comfort at speed is reassuring, where the VMax is, "hold-onto this, be brave." Of course the VMax was designed in the early/mid- 1980's, while the FZR used tech from the Yamaha international roadracing team's efforts, like the wide-beam, aluminum perimeter frame, and the Marvic-copy aluminum cast wheels using tubeless radials (Marvic uses magnesium). Then there is the 5-valve cylinder head, Genesis design. The FZR1000 made more RWHP than the Gen. 1 VMax, and it was well-under the street weight of a VMax, by about 120 lbs. with great aerodynamics and better suspension.
I think Sean had a FZR600 with an FZR1000 engine in it, for awhile.
