Not really vintage but . . .
Is that yours Don...?
That was my GSX-R750 track bike. Showa (titanium nitride coated) superbike forks and monoblock calipers, complete race exhaust, Ohlins shock, PC, Brembo MC, racing tires, and custom mapped by a brilliant tech named Nigel who worked on the AMA Corona Suzuki team. It was really dialed in -- at least for me! I sold it when we moved to a house with a much smaller garage. 
It handled even better than my RC51.
Very nice mate, that would have been hard to part with. You know, almost any street bike thats been set up by someone that knows what they are doing will blow most stock suspensioned bikes away. I had an Old 1988 Kawasaki GPX750 {Ninja in the states} race bike that was set up very well, it was without doubt the best handling road bike i've owned and blew most of the modern bikes at the time away, this was in the late 1980's. A couple of my racer friends rode it on the street and couldn't believe how well it handled, it was so neutral, even with the 16 inch front wheel, I never changed the settings from the track when i put it on the street, I used to ride a bit harder then...
That bike was set up, believe it or not, by a HRC mechanic Gregs boss {previous owner} had work in his shop on an exchange program from Japan, he did things to that engine that most experts at the time said "wouldn't work" especially the amount of weight removed from the crank, the engine was an absolute gem, it was a real buzz riding that bike on the street....
