I wouldn't say it's common, but it does happen. A skid in a car due to something like an oil spill in a corner would be a lowside on a bike, and a bit of a slide. With reasonable gear (leather or high-quality textile, with shock-absorbing pads), it's relatively undramatic, but rather annoying.
It's just the nature of 2-wheeled vehicles of all kinds.
