Kymco Xciting S 400 - 0-100 km/h - test 3 (no top case or additional helmet) 

2019 EURO 4 model - Polini variator (with the contra spring provided installed)
I know that 100 km/h on the speedometer doesn't equal to 100 km/h GPS, but unfortunately my phone records GPS position only at 1 Hz (i.e. every second, which is very poor to accurately assess an acceleration).
Also, as the center speedometer sometimes randomly lags, I am using the left speedometer for time measurement.
