Me and a friend were in Copper Canyon First week of January. We had planned on riding from Creel to Urique and then on to Batopilas. It would have been a great route other than when we got to the river crossing 10km south of Urique, the river was to high to cross. We had to turn back to Creel. It rained on the way back to Creel and the roads were pretty muddy and slick at times. We were both on 250's so we got around really good. a locl tour guide at Creel said the road from Creel to Batopilas is still under construction and impossible to pass through at times. You might ask around at Creel before you leave and hopefully someone will have updated info.
Typical road into Urique:
