You know on that type of fork @Iron is there any damping or fluid etc. or is it just firm springs to provide some sort of give? I've never got involved with that design but I do like the look of them.
@Eldon - yep there's no oil, just springs (hence called springers). If you look at the bottom of the forks there's three bolts on a lever arm that allow movement. The front one is fixed to the spindle (axle) then the second is on the front legs of the forks and the third one is on the back legs of the forks. As the wheel moves it moves the arm that then moves the front legs of the forks to compress the springs. They work really well and look pretty neat. No maintenance other than keeping shiny and oiling every so often at the sprindles.
