I was doing 150+ yesterday on long sweeping bends, the balance and stability with it's new adjustable 22mm rear bar is out of this world, not even a merest hint of rear wheel steer unlike the std sloppy crap with "bouncy bush" and "wobbly bar".
Depending on what you want custom bars out of correct ENT16 steel can be done no problem at all, front or rear, even to use with comnpression struts no problem.
