    I thought it would be good to keep track of these. If you find a credible one please post it and I will update this first post. If the engine is on the limiter then the bike might be able to pull taller gearing and therefore a higher top speed.

    Honda:
    2019 CBR250RR - 181 kph - not on limiter

    Suzuki:
    2017 Suzuki GSXR250R 139 kph - 129kph on GPS - could be on limiter

    Kawasaki:

    Yamaha:
    FZR250 3LN3 190 kph - not on limiter

    Should it be on limiter for top-speed? Or at power-peak?

    I can see using redline for highest torque for acceleration. Top-speed is determined by max-power. Tip from some guys I know with speed-records at Bonneville.

    The original post didnt specify that it had to be on the limiter... just that if it was then potentially more speed could be had with a change in gearing.
    Top speed is related to RPM... if it cant hit the limiter (max safe RPM) in top gear then it doesnt have sufficient power to get there and where the RPM are constant and speed is constant that will be TOP SPEED... there are a whole lot of other factors that need to be taken into account such as drag, altitude, gradient, weight of the rider, relative humidity (related to drag), tyres (size, construction and rubber compound) and the list goes on....
    Top speed will be where the speed doesnt keep climbing... regardless of being on the limiter or not, as shown on the video's above.
