Brian Rice made a simulator with everything you would ever need to estimate the range and charging trade-offs with a variety of electric motorcycles, including the Experia: https://observablehq.com/@briantrice/electric-motorcycle-travel
I'm not an idiot...but I'm not smart enough to use that for anything.
I have enough miles on my Experia to just "know" how much I need to slow down to get where I'm going. I'll even say its different bike to bike and rider to rider, even among Experias. I've ridden with another Experia owner. We charged at different rates on identical chargers at the same time after the same ride together. We had significantly different SOC (10 or 15 percent difference)even though we rode the same roads, routes, and conditions (Because we were riding together) when we got to chargers.
If you're going to tell me that the differences can be attributed to the lane position or the drag efficiency of our helmets, then your simulators are useless.
It's like trying to use ABRP to get to a place. It never works for me and it is never faster than just winging it like I always do. Probably works better for cars, but for electric motos ABRP is not worth it for me.
Of course your mileage may vary.
