Turtle Shell On A Monkey Bar

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.

"How bout that turtle shell on a monkey bar, his tiny helmet had huge skulls painted on it and he was barely able to hang onto his monkey bar because it was almost too high..."
