There's a brown LIKE seat for sale on eBay at this time. Has a small hole in it.
If you need one to attempt a modification for improved sitting on our scooter.......
I'm going to have a heavier grade seat cover, and re-shaped and added padding, and if there are stitches which might leak I'll slip a rain cover on it. Talking with cycle shops at present to locate the maker of my new seat. I'm going to get my spare seat re-done this summer by a pro - apparently this is a common thing for motorcycle riders..... then, Bob's Your Uncle~!
Happiness!
