I am a psychologist by trade and I know that people can develop hallucinations in later life, but I recently acquired an 09 R1200RT and to date I have not felt the need to replace either the seat or the windshield. In over 20 BMW motorcycles, I have either replaced the windshield or the seat of necessity with no exceptions. I am now almost 66 years old and my back is not getting better than it was 20 years ago. The seat and the windshield seem to work just fine and the ergos are perfect. Any ideas? Similar experiences?
