Best of luck to you, getting old is not for sissies. I hope that there is someone in your Family
that you can pass on your Bike to, who will love & take care of your Bike for you.
I'm relatively new around here, but hate to see anyone "leave the family" as I like to think we bikers are. Good luck to you sir; keep a positive attitude & remember none of us visit this forum while actually riding - you can still come around & I hop you do!
This thread is difficult for me to read and post on as I am 74. Life is a series of challenges and never a bed of roses. Stay positive and face it head on.
I will face the time when I will need to make the same decision. I can only hope that I do it as well as you have shown.
