When I bought some leather furniture a couple of years ago the salesman handed me a couple of bottles of cleaner and protector. Excellent product for the bike. It's great on black plastic and the seats. Non silicone base. I used to use armorall until I read the bikes owners manual and saw that is suggested a non-silicone base cleaner/conditioner. I didn't see silicone in the ingredients in armorall but it listed another ingredient that when I looked it up in Wikipedia I found it was silicone. Theses products clean and condition without changing the matte finish that most Beemer black plastic parts exhibit.
