Men who ride Harley's or other cruising type bikes, who wear turtle shell style helmets because they are not driving fast enough to need a full helmet usually. And they ride on a bike that has had custom steering handles installed. The handle bars are usually raised an additional 10 to 12 inches, making the rider appear to be hanging from a monkey bar.
