I owned a ZX11 and man was it fun in a straight line if you didn’t have to stop soon.
I used to tell people if you got on the throttle, you’d better have someplace to go because you will get there faster than you can think.
Every season, it would take a month to get used to the power.
After years of dealing with it, I determined a ZX6 would have been a better purchase.
I’d probably get a GT350 or Boss 302 before I’d get one of these monsters.
Back when we had the 1/8 strip here, the 600s would often beat the open class bikes in the novice classes (all there was, really).
