Right, the fronts take a real clamping, but that is a good thing, at least IMHO. I'd rahter know this ahead of time and not have the bike do an unintended brakie. I have though been on it hard enough from 60 MPH where you have to be sparing with the rear clamps.
To me the bike feels well ballanced. I have yet to push it where the frame flex comes into play. So far it is more than nimble enough.............
