Thanks for the replies. I would have thought that there would have been more suspension travel on these but it doesn't sound like it. Now I know that it is not to worry about.
I checked my x1100c and did not see any type of stopper, it seems like the only thing limiting travel is the length of the shock absorber. Next time I have it in what we call "the overload mode" I will measure the travel in the rear.
Usually on coilover type setups like the IRS units, the bumpstop is located on the shock itself. On these machines it would be under the upper bellows on the shock and cannot be seen. Some other units still have the rubber bumpstop on the frame or control arm but also have it on the shock.
Without the bumpstop on coilovers, the spring would bind at full compression and could possibly cause damage to the spring or shock itself.
