Hi Trippy
They are great I ride round that way a lot it is very dry up there at the moment so if you are going to go on a gs now is the time to do it
It gets a lot harder in the winter when we have had some rain I ride an old XT500 up there most of the time but have ridden most of them on my GS with no trouble (in the dry )
I’m a bit pushed for time at the moment but if you would like some more info let me know and I can give you the SP on most of the tracks in that area
