Probably just the gasket on that large roundish cover on the right side of the engine. If you can't tell for sure where the oil is coming from or have doubts. Wipe/wash the area good then start the bike and let it run till you see a drop hit the floor. Now shut it off and take a handful of baby powder and while holding your had close to the area in question blow the powder toward the area. A compressor and blower works best but the idea is to dust the area with powder. The leak trail becomes very visible when you do this as the powder dust sticks to a thin oil film like it was glue.
