Thank you for your note OY3/10.2.30.
You will observe that our recent memo re.
radiator "jellying" deals with the point you raise.

The frame is so weak torsionally that if you
could disregard all thought of riding comfort we should not
be able to use appreciably more damping than we do at present,
because if we did the shock absorbers would cease to function,
and the frame distort as a whole.

We have actually tried out shock absorbers
connected in the manner you suggest in the very early days
of "shimmy", when the lack of rigidity of the frame was
brought to light. It is of course the old principle of
a stabiliser and if we succeed in making our frames
sufficiently rigid in front, we may succeed in getting
some advantage out of the arrangement.
