Chunky needs a new whip...

Usually known as kidney belts. I have had them for years.
Stops your back muscles getting chilled/aching
The modern elastic and Velcro kidney belt used today was born in the late 1910s and 1920s. It was invented specifically for early motorcyclists to protect their lower backs and internal organs from the intense vibrations and jarring impacts of riding un-suspended bikes on rugged dirt roads.

I'm going to order one to see how I get on with it! A lot cheaper than a new bike/new suspension

I have this one. With a removable warm insert.
Some have thin, spring metal supports at the back.

Yeah, I've already got the high seat.

I'm inexperienced, but I've done nearly three years so far, so I'm not *that* inexperienced. The rest of me is okay; I don't get a numb bum, arm fatigue or leg fatigue (which I did on a smaller bike); I'm pretty strong, so I don't have any other bike fitness issues, it's just my back, which I struggle with off the bike as well to be fair. Maybe the V85 is comfortable enough for somebody with a healthy back, but it doesn't work for me. I'm exploring my options. Thanks for the thoughts, though.

Sounds posture related to me.
