I've been out enjoying my new-to-me r11s as much as possible. Snowing today

Hopefully will get an Indian summer. Maybe its the material BMW used for the original seat or partially the shape but it seems awfully slippery. More so than my K bike or any other bike Ive ridden. I know, this sounds like a minor, annually-retentive complaint, and I guess it is. But does anyone know of a product one can spray on the seat or the seat of riding pants to lessen the slipperiness? Maybe it's a matter of just getting used to it.
