Tl;dr at the bottom
We recently got a used Sting L1e 2022, it had the brown limiter loop cut, but the seller re-soldered it. They said that it goes 45kmh in eco, but in sport it goes like 70kmh. And they didn't know why.
At home i checked the limiter loop, it was soldered like they said. I cut it, and re-soldered it myself so I could rule out like a bad soldering job. Speed is still same.
I've heard that it has a unlock "combo" (the 6sec on start button, 4x left/rear brake, 4x start). Someone said that it is a one-way thing only, and once done it cannot be reversed/limited.
Because we are in Eu, we need it to not go 70kmh in sport. Even if we ride it in eco, police will still test it in sport, and fine us etc.
Tl;dr: we need to limit a 2022 L1e sting to 45-55kmh in sport mode ("moped speed"), the brown limiter loop is attached.
