Switched to an R 1200 last year after 30 years on Goldwings. It was time for a change, and the BMW checked all of the boxes. Decided to take on the service work as appointments with local dealers were only available after a waiting list of a couple months. Suspect that having not bought the bike from a BMW dealer that it may have had something to do with it.
Retired now, and the time is available to learn. It has been a challenge that I have, and continue to enjoy. Decades ago I worked on my bikes because I needed to. Now, because I want to.
All the best
