We went up October 2017. Thanks to the 4wd guys who had cut down a lot of the tree branches from the snow fall this winter.
2 x Dr 650, 1 x KL650 and 1 X Triumph Tiger XC.
All made it to the hut bar Tiger. He (I) stopped about 1/4 of the way down at the first steep gut. Good call too from the sounds of things.
Good tyres helped but defiantly as far as you can push a heavy adv bike.
