You are confused. What I mean by a 50 amp station is it outputs a maximum of 50 amps. Now, as they rate EV stations they use a BASELINE voltage at the EV maximum, which is 500 volts. I don't know if any vehicles actually operate at 500 volts, but that's how they measure it. 50 amps x 500 volts = 25kW. That's why it's called a 25kW station.
The EVgos you mention that claim to be 50kW stations are merely 100 amps. Because 100A x 500V = 50000W. The important bit is that vehicles operate at different voltages. The amp number is set in stone, but the voltages fluctuate. You notice when you charge your Energica you can set the requested Amps? With yours I'm assuming it's an 80 Amp request. Energicas operate between ~280-340 VDC. This means at near empty, the bike will request around 80 x 280 = 22.4kW. They'll actually request more amps than that sometimes because they're awesome.
As it nears full, the voltage has been rising the whole time. 80 Amps x 320 Volts = 25.6kW.
A LiveWire operates somewhere in the mid-high 200 VDC range. Therefore a 50 amp station, as found at H-D dealerships, is going to deliver somewhere around (50A x 260V =) 13kW for a LiveWire and (50A x 300V =) 15kW for an Energica. If a Zero was able to accept CCS charging, at the same 50 Amp station it would get (50A x 102V =) 5.1kW. yaaaay.
