Chatter, rear-end pump, uncontrolled wheelies: We’ve all been there, right? Maybe it’s the fact that when we hold our hand upright—heel down and index finger on top—it somewhat resembles a motorcycle. This way we can show slides, wheelies, and any other handling characteristics to anyone that will listen. Need to be more specific? Hold your hands as though you’re gripping the bar(s) and describe, with loud noises, how the motorcycle was moving underneath you.
