Try any old Moto Guzzi... KTM clutch/transmission is silk smooth after that
My guzzi is like shifting a tractor. It makes for some interesting practices while ripping ass up a canyon road.
As for the 640 just be nice to it. I have seen guys try to mash gears on bikes and it is just wrong. If you are needing to stomp it you are doing something wrong. With a little time it should break in nicely.
