I exercise regularly and am in good shape, I think, but a backrest is a must for me on any long ride (>200 miles per day). I tend to slump when riding and the backrest forces me into a better posture. Also helpful are compliant shocks, and when I moved from the 12" SG shocks to Progressives, then eventually to Ohlins, I found that I could ride longer without back issues.

In 1997 I took my first long trip on my new (for me) RK with stock seat. Back then HD had no backrest options, at least for the RK, and in no uncertain terms the ride left me with the realization that at least a backrest was in my future. There was one aftermarket backrest on the market but its design wasn't very elegant, so I ended up buying a Corbin with a backrest. That was the ticket and I never had problems thereafter. My present SG has had a Mustang installed with detachable backrest since new and it is the equal of the Corbin in terms of comfort but much cheaper.

 

The backrest was some of the best money I have spent on the bike. I've got a knackered back because of flying on a ejection seat and the back rest has sorted it all out.

 

You have too much money in your wallet which you carry in your back pocket, even when you are sleeping! If that is not the case then get the back rest. I would rather ride bare foot as opposed to not having the backrest...

I hope this helps your back and you can continue taking the long rides

 

you deserve a little break.
Congrats on completing the ride.

 

Adjustable backrest

 

I agree with the stretching and exercise. I have a back rest on order. Good luck with your plan. Its not fun riding in pain all the way home.

 

I've had back problems, but mine seem to go away when I ride. The exercise and weight tips have worked for me. I just took a 2600 mile trip on my '09 FLHTCU with the stock seat and had no back issues, which actually surprised me. I found the small of my back was supported by the rear portion of the rider section of the seat. I've had Corbin backrests on two sport touring bikes and on my former Victory touring bike and found them irritating, but then again they probably weren't anywhere near as plush as the backrests others are using on this thread.

 

Backrest works for me as well.

 

I have a back problem also MY Wife
is always on it over something, and
when she has been on it long enough
I'll fire up the wheels and go for a ride

 

Backrest or less vigorus woman.
