Tuning ABS sensor wheel (+10 km/h/) for Vespa GTS 300 HPE

ABS/ASR sensor wheel (Speedwheel) for Vespa GTS HPE 300 (from year of construction 2019).

The Vespa models built after 2019 have a much more powerful engine, but due to the speed limiter that starts very early, they do not reach a higher top speed. A top speed of 10 km/h faster is achieved without intervention in the motor control. The sensor wheel inductively indicates the rear wheel speed to the receiver of the control electronics.

Calibration of the speedometer

The rapidly leading speedometer display is recalibrated, which means that the vehicle reaches a top speed that is 10 km/h higher. The legally required speedometer advance of 7% is hereby obsolete, so this is a NOT APPROVED TUNING PART. After installation, the ABS and ASR must be new be calibrated, this is easily possible with a few simple steps.

Installation

For the assembly, the exhaust and the swingarm on the right side of the vehicle must be dismantled. The sensor wheel is mounted on the rim and is secured with 5x M6 screws. You simply exchange your sensor wheel for the speed wheel. After that, the ASR and the ABS must be recalibrated.
