Same here!When I ride without gloves, not often, the BMW grips leave my hands with black marks also.

No kidding. If I don't have a helmet and gloves, I don't ride. However, most of the time, it's ATGATT for me.I want to seriously suggest that you wear gloves when you ride, you would be amazed at how badly a hand gets damaged at even t a 5 mph fall.
