I know there are places that make a clear, stick-on, "pad" like what a lot of people us on fenders. But I think what you're looking for is a retro-looking knee pad like Triumph and others had. That would be cool! I haven't seen any but will be watching for some too..... Jim

It's not on RT, but it is tank knee grip. My left leg amputated and I use my knees a lot to hold on in tight turns. I put these knee grips on my F3-S. I can't remember exactly what they belong on. I think it was some kind of older Honda. Found them on Amazon.com.
If knee pads don't find anything, try other words, like tank protector, knee grip pads, or something else.
They came with peel and stick, had the good glue already on them. Be sure they are in the right place. When you stick them, they are stuck. They are hard rubber with maybe 1/4 inch deep honeycomb type place for your knees to press against. Been on there about 3 years now.
If they are peel and stick, rubber pads, they should be flexible enough to conform to the curved surfces on the side of the tank.
Several pages of tank pads for various scooters listed here. If it has the demensions in the product information, you can figure out if they will fit. The picture will give you some idea how they conform to the space on the side of the tank.
You can cut the edges on some of them. If they have some logo, you might be able to remove that with a side grinder or a Dremel tool and smooth it back out, or maybe even JB Weld your own logo over it. 3M also has an epoxy made just for rubber and plastic products that is super strong and water-proof when cured.
Amazon and Ebay has hundreds of them. I have them on my Moto Guzzi and I put a set on my Spyder where my wife's folding passenger pegs causes her pants or boots to contact the black paint. Peel and stick. I cleaned the area with rubbing alcohol and they have been secure for three years. IMG_20221119_103903533_BURST000_COVER_TOP.jpgIMG_20220901_111603739_HDR.jpg
