Haven't had the opportunity to test it. Had to reduce it to 50km/h for the showing at the local authorities. I think the top speed was reduced to 56% when I showed it, and then it did 46km/h on a calibrated bench. So, maybe max is close to 90km/h? 80? Not gonna try, I want it to stay road legal, so I've adjusted it to reach about 55km/h no matter what I throw at it, and maybe 60 under ideal conditions.
