So I am in the first week of my 3 week adventure to Alaska on my new 1290 SA. On Wednesday afternoon I decided to take the Dalton up to Deadhorse. So I left Fairbanks around 3:00. I arrived at Coldfoot about 8:00 and everything was going well, other than a little rain here and there. About the last 36 or so miles before Deadhorse they were working on the road. I only had about 25 miles to go and was trying to finish around midnight. Well at 12:10 AM I hit a fairly large rut in some soft ground. The bike immediately pitched to the right and I hit the ground hard at 50 mph. When everything stopped moving I was under the 1290. I managed to kick it off and stand up. Followed by an immediate fall to the right as my knee gave out. I sat on the bike for a couple minutes and watched to trucks drive around me barely slowing down. Luckily the next two drivers stopped and helped me stand the bike up and move it to the side of the road and then they left. I re-attached the right pannier that had been ripped off and the other parts that I could find. I could hardly stand but managed to get on the bike and continue on to Deadhorse because I had to get gas to make it back to Coldfoot. I assumed I was going in the right direction but I guess I got spun around in the crash. I ended up going 25 miles in the wrong direction before realizing what I was doing. I made it to Deadhorse around 2:30 AM and then turned back. It took me until 5:30 PM to make it back to Fairbanks riding at a much slower pace. Quite a long night. Went to Urgent Care Friday morning, they suggested an MRI and an orthopedist. Orthopedist diagnosed the problem as a torn PCL, torn meniscus, ACL twisted out of position etc. Told me there is no way you could ride the motorcycle back to Iowa. So I am going to store the bike here and hopefully I will be well enough to pick it up before the snow starts.
