I was in this section of Italy TET about 3 weeks ago. I also ride a Honda Africa Twin with TKC70s. Similar tyres I guess, you may even have more offroad bias than me. (BTW how do you find these tyres on the road?)
I Started in Arona and got to the Alpe Soglia mountain climb (Corio)
I was also traveling alone with about 20kg luggage which included camping gear.
First it was a blast. I loved it. Some sections were quite challenging, but I never felt that I was taking huge risks and I always thought that in the case of being stuck, I would find some locals that could help me out.
There are some points I missed because of of warnings in the GPX files and when I got to them I thought it be better to go around. (I cannot find and example now on google maps for some strange reason)
I made a 8min vid of the ride but Youtube did not like it so it lives on a enduro chat group in Telegram. Here you will see how some sections of the trail look like. You are welcome to join it. (https://t.me/joinchat/H9nNCxUcgqBhvFVoPRdyDQ
) my handle is Mastercore. You should find my video in there somehwere.
btw: I had planned to do the whole western section of the Italy TET but ended up turning back at Soglia because of an injury to my left wrist. Also I went the week before we had the heat wave in Europe, so lucky I was not on the trail through 40dec heat!!
