Here's a look at the Aprilia and Vespa Scooters at the Auto Expo 2018. The Vespa Elettrica runs on a power unit capable of delivering 2kW of continuous power, with peak power at 4kW. While the SR 125 is expected to use the Vespa 125' engine where it offers 10.06PS, though it could be in a higher state of tune given the sportier positioning of the Aprilia.
