I don't know if anyone really knows the top speed of a stock derestricted bike. People who remove the limiter are also likely to retune the bike, which adds around another 30hp to the wheel.
There have been other threads where people reported their top speeds, though was everyone honest? How accurate is the speedo? Did they use GPS?
The size of the rider, rider position, windscreen presence, will all affect top speed.
The answer is going to be between 235 and 300. I'm guessing much closer to 250 than 300.
