    Yes. I like Kevin Cameron's theory-
    "If you want a faster bike, become a better rider."

    258 indicated does not mean actual.  My speedo reads high, like most.

    4-5% for my Z900 (checked with GPS) with Metzeler M7RR (tyre circumference could alter the result to a certain extent)

    I just noticed the 242 kmh GPS reading in corner of the screen.  Much more realistic.  Top speed is very ambiguous at best.  That's why 2 way runs within the hour are standard at Bonneville.  Wind and slope play a large role.  I love the gearing discussions where guys speculate that a very small rear sprocket will push them past 300 kmh :158:
    As to ECU limit, I suppose that if the gearing allows getting to the redline, the ECU would actually be limiting top speed.  As far a I know the standard Z900 is not speed restricted electronically.

        I had a clear stretch of highway a few days ago and was 20-120 in a flash, then it was climbing slower and it got a tad bumpy so I backed off. Iím really going to experiment in the spring. I am getting my ecu flashed, and Iím getting some new tires. That should change things a bit.
