Good luck with your trip.
Had a RTW biker drop in here a couple of years ago. He had ridden east from England and got to Kashgar, where the Chinese would not allow him to pass south through Tibet to Nepal. So he ended up going north to Mongolia for a ride around, then flew with his bike from Ulan Bator to BKK. We met him later in Laos. So, need to get all permits required for crossing China and would need a local agent to organise. Possible but not easy.
We had a great ride across Tibet a few years ago with the Himalayan Roadrunners;

They have been running bike tours from Kathmandu to Lhasa and back for the last 20 years, but it's never a guaranteed trip. In fact last years trip was diverted to within Nepal, due to severe landslides on the pass up to the Tibet border from KTM.
Tibet is a surreal place to ride, but hard work. Altitude, poor food and accommodation plus changeable weather. Stock up on Diamox for altitude sickness prevention and Cipro for stomach viruses.
We were riding tough old Enfields, so no problems with poor fuel, rough terrain or altitude, but need to check a modern bike is up to it.
Good luck
