Bill, you need to look at Regina's seat.
Wait, let me rephrase. Bill, you need to look at the modified seat on Regina's HDM.
I used a narrow battery.
I moved the CPU into the freed space in the battery compartment.
I used the stock pan and cut away the nuisance CPU relief ridge.
I had Mayer http://billmayer-saddles.com/
make a custom, lower saddle and match the stock cover design.
I'd post a pic, but she's off riding on the north coast with Jamileh somewhere. Expect her back on the weekend. She now does 600 miles in a day without complaining.
Found this one. Frost and all.
I have a Maund seat on my EV and it does alter the appearance.
