Welcome Andy, you will find that all Morgans with the sliding pillar engineering give a 1930's ride as its 1930's or earlier technology!
As many here say, you can improve matters by refining the setup, tyres, dampers, panard rods, ptfe or roller bearings added to the front spring reduces windup, progressive springs, brake reaction bars....etc etc
All can improve ride, Cain at Wolf Performance can add any refinements for you hes in Royston...or like many of us older hands, have a go at refinements yourself!
Its all part of the fun in owning a Morgan!
