Between the 750' and 1000's built between 1980 and 1985, the fastest bike was a 750. The only thing faster stock was a GPZ1100.

And that 750 was the 84-85 GPz750 Turbo :)

I think Lorcan ran 170-175 mph on a stock GPz750 Turbo, and after he modified it a little he went 211 mph :)





Is that "useful info"?

Yep. I still remember reading in one of the bike magazines back around 1983 (?) that the GPZ 1100 was the first completely stock bike to rip a quarter mile under 11 seconds. It clocked a 10.88. May not seem so great today, but it was the first production bike to do it.

Where's the beef?

Talk of performance figures brings us back to good old MIRA and the Great Debate (perhaps that should be Mass debate) concerning precisely how fast the GPz1100 is. The story starts with the American magazine Cycle who, after one day's testing produced quarter-mile times in the low 11-second bracket and their dyno testing subsequently gave an astonishing 104.4bhp at the rear wheel, nearly 10bhp up on anything else they'd dyno'd, returned to the strip with a professional drag racer.

This superlight jockey fiddled with suspension and tyre pressures before climbing onto the saddle and blasting the GPz to an earth-shattering time of 10.88 seconds. Cycle's own drag artist couldn't match that but recorded a 10.912 sec/124.65mph pass to crack the 11-second barrier for the first time in the magazine's history.
