| contd :- -2- We are making tests to determine the amount of free movement that we require to enable us to get the best riding results for ordinary slow speed main road touring. These consist of finding the average spring deflection under such conditions by means of the Chronograph. Hs{Lord Ernest Hives - Chair}/W.A. Robotham. | ||
