125mph over a standing 1/4 is how it goes in the taller gears , it has also seen 240kmph+ by the end of EC main straight,
ride clutch, it should be a progression not just a step, stepping will break drive line at 7000rpm, the key is to load the drive line then progressively lift foot off clutch pedal and hold on.
