People are too much concerned about topspeed but after 5 years in pure bike tourism i can assure you guys there's no such thing as topspeed.
All that matters is stability at high rpm's and power.
60km/h is more than a high speed when cruising in rough track. And 120km/h is not enough when you are cruising on a highway.
So even if the bike is hitting 140km/h it's useless. The main question is for how long the bike is going to maintain that speed?
