In the United States most motorcycle accidents involving more than one vehicle the motorcycle is not at fault. It’s really common for a car driver to not use a blinker, or not see a motorcycle and cause an accident with a motorcyclist.

Same thing everywhere else. Cars not signalling, suddenly opening doors into traffic, idiots jumping out of bushes etc etc.

The distant second place is road condition - surprise potholes, open manholes, spits of concrete, pools of lubricant and cooling fluid after previous crashes is also nice.

And only then comes something that can be remotely called reckless riding.
