Sorry to hear of your aches and aggravations.
I'll be 69 in a few days and have arthritis in my hands, feet, shoulders, and some new places this year, as well as D.I.S.H... I'll save you time in wondering what that is...
Diffuse idiopathic skeletal hyperostosis (DISH, also known as Forestier's disease, senile ankylosing spondylosis, and ankylosing hyperostosis) is a non-inflammatory spondyloarthropathy of the spine. It is characterized by spiny ankylosis and enthesopathy (ossification of the ligaments and entheses). It most commonly affects the thoracic and thoraco-lumbar spine, but involvement is variable and can include the entire spine.[SUP][1][/SUP] The disc spaces, facet and sacroiliac joints remain unaffected. Diagnosis requires confluent ossification of at least 4 contiguous vertebral bodies.[SUP][1][/SUP] Classically, advanced disease may have "melted candle wax" appearance along the spine on radiographic studies.[SUP][2]

I usually tell people that I'm getting a rigid frame, can't easily do simple things like bending over to pick up things, put on my shoes, etc. Not complaining, just trying help you relate.
You can ride more comfortably, but it may take some trial and error, and money, to find out how. I ride a 2012 RT... I replaced the following with all Can-Am parts: seat - gave me another few inches of wiggle room; handlebars - adjustable handlebars, gives me some options for arm position; front footpegs - front floorboards - gives me room to move my feet to different positions. And a non-Can-Am strap-on air cushion.
All contribute to my overall degree of comfort, but none are
the solution. I still start squirming on the seat/floorboards after an hour+ into a ride, but did manage a two hour ride earlier this summer. But I was squirming a lot by the end of the ride. Far cry from the days of riding straight through to Daytona on two wheels.
But, I'm still riding. Year round. And I will continue until when... Some ride is better than no ride.
Talk to other riders for ideas, see what worked for them... that might work for you. Dress for comfort as well as function.
Be prepared to spend time, and some money, to find out works for you. I'm kind of stubborn and don't take any aspirin, etc... but as a co-rider, a few aspirin may help your discomfort tolerance ;>)
Ride safe and enjoy.[/QUO
Thanks for the info. I am a passenger on the RT. I had never been on a motorcycle before. We will have ours for 3 months in a couple of days. These are all ongoing problems, but now I have to apply my doctor's suggestions to the use of the bike.
