Guys I am no longer a bike expert my last 2 were cardan drive for exactly this reason.

I wouldn't expect a long life from such a system coupled to a huge engine and a poor cush drive. Maybe HD forums could comment.

I think I remeber bike chains lasting around the 10 -15 k mark with low power bikes like CB360 or Triumph T140Vs
