Thank you everyone. We just came across the road from Isiolo to Moyale.
It had been raining pretty much every day in Nairobi and it rain on us when we arrived in Isiolo. We heard that the road was in very bad conditions so we decided to rent a 4x4 Land Cruiser and put the bike on it.
By the time we loaded the bikes and hit the road was noon. We rode for 18 hours straight (mostly at night). The driver had never driven a 4x4, was high on chat and the road was in very bad conditions. We passed several trucks that had been stuck for days and we had our share of digging and pushing.
Here is picture of the beginning of the road:
We rented the truck from a guy in Isiolo named Mohamed (+254 721 708968) and his son Wako. We do not recommend them as it was a BIG hassle to deal with them. We paid 550 USD for two bikes. There is also a guy in town that help us find the pick-up truck his name is Kala (+254 718 218 010).
The road is doable if it hasn't rain in at least 4 days but otherwise plan for several days pushing the bike through the mud.
