It doesn’t throw around as nicely as a 550xp or an MS261. And doesn’t cost like one either. And doesn’t have the undesirable (IMO) electronics.
I agree, I think the 5105 is the best value in the 50cc class. That’s why I bought mine.
I compare it’s handling to my old Jonny 590’s. In that it falls short, and I think most would agree somewhere through the first tank.
